Conference begins. Really, the biggest update we have just over the last half hour from Josh Campbell and others, reporting that human remains, believed to be human remains have been found near the site. Reporter thats right. Thats something that will be asked at the press conference in a few minutes. Were expecting to hear from the mayor who is actually instituting a curfew around the area of the blast site. That started at 4 30 local time this afternoon, will go through sunday afternoon as well. This is to try to keep people away from the Downtown Core where investigators are really working on this. Where we are now, media are gathered, where the press conferences are happening is on Second Avenue but several blocks away from where the explosion happened this morning. You can see flashing lights in the distance where they blocked it off. You can also see theres pretty much nobody on the streets. Thats what a lot of downtown looks like now. Granted, it was already pretty quiet in nashville this Holiday Season because of covid19 and other restrictions and such, of course after this, a lot of the downtown area was cordoned off. Ramps, freeway ramps into the downtown area also sealed off today. So we are expecting as you mentioned to hear from the mayor. Were going to be able to ask questions to the fire chief and police chief about the latest in the investigation. Of course, fbi, other federal authorities, are working on the scene but were told will not be present at the press conference coming up. Were having problems with natashas communications. Were awaiting the press conference as she was telling us, a press briefing on the national explosion. For more in the investigation, lets go to senior justice correspondent evan perez. Evan, what are you hearing . Well, anderson, the fbi and the atf are sending in resources to help investigate whats clearly now a vehicle bomb that happened this morning. As you pointed out earlier with your interview with a witness, you know, the timeline is rather strange. You start hearing these reports of gunshots. We dont know whether theyre actual gunshots but we know that people heard what they thought were gunshots and started reporting this to 911. The focus now for investigators is to try to figure out whether that was part of the target, were they trying to draw First Responders and was that part of the plan here or was it another target, perhaps one of the buildings that were badly damaged. One of the buildings you can see in some of the pictures is an at t Exchange Building which is why some of the telecommunications and natashas signal is having trouble, because theres been damage to the at t infrastructure in downtown nashville. At this point, anderson, we know the atf is bringing in the National Response team, bomb technicians, chemical experts. Theyre going to go through the crime scene analyzing pieces of debris there to see if they can figure out what was used to start off the explosion. One of the things thats happened in recent years, anderson, is that the fbi, federal Law Enforcement made it clear to people who sell these types of precursors, chemicals that could be used to make explosives, that they should notify Law Enforcement when somebody is buying large quantities of it. Thats one of the things happening now, the fbi, atf are trying to reach out to the suppliers to see whether anyone bought large amounts of things that could be used to set off Something Like this. As you can see, it is a pretty devastating blast. We were talking to a bomb expert a short time ago that was saying the type of explosive will lead the investigation Different Directions depending what it is, commercial grade, military grade, improvised or homemade type of explosive. Right. Obviously the fact that, anderson, that somebody set this thing up, it appears either remotely or perhaps it was a timed device, those are the things that right now investigators are trying to figure out because obviously somebody was setting off, set this thing off at a time of morning, 6 00, 6 30 in the morning Christmas Morning in an area of downtown thats not exactly the area where the bars are necessarily, a couple blocks away. Perhaps they were trying to avoid casualties. The fact you were hearing messages, one of the messages we heard in some recordings that we have seen on social media says if you can hear this message, evacuate now. Thats why frankly there wasnt more casualties but obviously were trying to see, investigators are trying to see whether the possible human remains that have been found are associated with this incident, whether the person who set this up was still in the rv or whether some innocent bystander was harmed by this. Again, thats part of the investigation at this point. And as we await the Police Briefing which we anticipate happening any moment, it is strange, evan, you talk about the timeline, we talked to Betsy Williams who lived in a building that she when she woke up hearing what she thought were shots looked out, saw the rv, heard the message, eventually evacuated. She said the count down that occurred, 15 minutes until the bomb blast goes off, it was counting down each minute, then they had evacuated, but it didnt explode after the 15 minutes were up. She estimated it probably went on another 15 or so minutes. And then exploded. Hard to understand whether thats just intentional, accidental, it is not known. Right. Exactly. Thats part of the mystery here. Again, if you were trying to draw Law Enforcement in, some of the First Responders, and if this was a bomb aimed at them, why is there this warning that cleared the area out. Police were able to draw people away. There was a witness that reported someone was walking a dog down the street in that area and the police were able to push that person away, tell them to get away from the scene. There was plenty of warning for people to get away from it. Then as you pointed out, the countdown is happening and it doesnt go off. People were starting to come back in to perhaps get a closer look. We heard from police earlier that at least one officer had some hearing damage but pretty much the miraculous thing today nobody was, at least from what we could tell, there are no confirmed fatalities at this point. That clearly could have been worse. Again, reports of human remains. Dont know the details of that. We expect to hear more in the Police Briefing any moment. Want to bring in andrew mccabe, former Deputy Director at the fbi. What kind of forensics will atf and fbi be looking at, and now the human remains, wonder what you make of that. All great questions. Human remains question first. That kind of elevates the sp specter that there may have been someone in the vehicle when the device went off, thats the question everybody wants to answer. With an x employe with an with an explosive device of this size, i dont want to get too graphic, it is unlikely you would find some trace evidence of human remains, but youre not going to find a lot of big things. Heres the mayor. The chief and i had a walking tour of the devastation on Second Avenue. As of, you know, right now, it does, initial evidence does show the Early Morning explosion was a deliberate bomb being set off in our community and the blast caused injuries and catastrophic damage to this very historic part of nashville. Now, at the end of the day, i think all of us, i certainly have gone from relief there were not more casualties, and thats an amazing thing there were not, particularly when people begin to see the devastation on Second Avenue, to relief there were not more casualties to now anger and determination and resolve, resolve to rebuild and not to be deterred and to bring whoever was responsible for this to justice. Now, i have spoken with governor lee who is working with us to have a declaration of a civil emergency, both with the state and then to work with fema to bring all possible resources to rebuild Second Avenue, to go forward, not be deterred by that. I am grateful to state and federal partners to help this important part of nashville rebuild and come back. There are 41 at least separate businesses that are materially damaged by this blast. There will be others as we see the full extent of this. But already, you can tell that it is going to need special help, special resources, and i am grateful to the state partnering with us to commit to rebuilding second. I want to stand with our downtown residents and our Business Owners for whom there was a terrible day, but we are, like nashville faced other challenges particularly this year, we can rebuild and get back to normal. As announced earlier, metro is also establishing a curfew in the explosion impact area from 4 30 today until 4 30 p. M. This sunday. Effected businesses, i would urge them to contact crystal lab at the central precinct to manage coming back to your facilities safely. In the meantime, the curfew area will provide safety and security for businesses in this area and i will go ahead and warn nashville, it will be sometime before Second Avenue is back to normal. It is not going to be the three days of the curfew for Second Avenue. The curfew goes from 4th to the river, James Robertson down to broadway. The police will take special care with that the next few days, and partners at the fbi have a large currency to investigate and need to be able to do that work effectively and well. Now, this mornings attack on our community was intended to create chaos and fear. In this season of peace and hope. But nashville has shown time and time again the spirit of our city cannot be broken. But were not going to rest until those responsible for this outrageous and cowardly attack are brought to justice and the full force of the metro police and partners at the fbi and atf are working together to make sure we will get back to being the safe city that we are. Now, three people have been hospitalized as a result of the explosion and are in stable condition. My prayers are with them and their loved ones tonight. I was able to visit with a fouryearold girl this morning who was had no injury, was saved, but lets just spend a moment in celebration of the six uniformed Metro Police Officers from our central precinct who were at the scene at the time of the blast. These incredible heroes who ran to danger with uncertain outcomes ahead of them were responsible for so many injuries being saved. I have spoken with chief drake. I can report that the officers who were injured by this are recovering well. I would like chief drake to come and spend a little bit evaluating the officers who took swift action, directed people away from danger to save lives, even at the time that their own lives would have been in peril. They are heroes. And i am grateful to them and all of nashvilles First Responders. This is a year we understand what First Responders mean to our community, time and time again, and unfortunately on christmas day, you have another example of that. Now, several downtown residents whose homes were destroyed by the blast, i am inspired by their resilience. And we have to draw inspiration from them as our city to be resilient once again and to get the resources to rebuild and i am grateful to the red cross who opened an aid shelter for those that have been displaced. With that, let me turn this over to the chief and answer questions. I think the message of the day is we are going from relief now to resolve to catch those folks and to rebuild our city, one more challenge in nashville 2020, but we will get through it, were grateful to our First Responders. And you see once again these officers running into danger to help save lives and injury. It is inspiring. And again, the gratitude of our Community Goes to the chiefs force. With that, i would like to turn it to chief drake to come in more specifically about the heroism, great heroism of our department. Thank you. Thank you, mayor cooper. As mayor cooper stated, these officers acts of heroism is tremendous. This morning they received calls for shots fired. Had no idea what they were responding to. Once they arrived in the area, they heard an rv giving out a message, basically saying it was going to detonate within a certain time frame, and countdown would go on. Then it would play music, countdown would start again. Officers immediately began knocking on doors and evacuating residents here, not knowing if the bomb was going to detonate immediately or go off in the time stated. These officers didnt care about themselves, didnt think about that. They cared about citizens of nashville and went in. We would be talking not about the debris that we have here but also maybe potential people. So with that said, the officers saved lives today and their heroism will be noted. Sir, do you believe that either the lyft headquarters or at T Data Center might have been targets of this explosion . We dont know. The investigation is continuing. We dont know the motive at this time. We are following up on all available leads. Is there any time why this happened Christmas Morning, anything that leads you to believe this day was chosen in particular to happen . Dont have anything at this time. We are following up on every lead we can. Why Christmas Morning, we have no idea. Total surprise. When i was briefed this morning, i thought maybe it would be a propane explosion from an rv and turned out to be an intentional act. But were going to follow up on every lead. We are following up on tips that come in now. Well continue the investigative efforts. Have you found human remains in debris . We found tissue we believe could be remains and well just have that examined and then be able to let you know from that point. Im sorry. I cant hear you. Can you speak ags to where it was found and whether it was from inside the rv . The rv was detonated, if there was someone inside, we have no idea. It was a large explosion. The investigation is continuing. Theres matter all over the area. Well continue to examine that to see if it is human remains. Right now, theres no known fatalities that we know of. Just the tissues is what you believe is human tissue in the remains . We believe, could be. But to be certain, we have to examine it, once we know for sure, well let everyone know. Were investigating it. Have you received any information of threat leading up to the city in the coming days, anything to lead you to believe this was something that was coming . We have not received any threats whatsoever. Total surprise. As i said, when we got the call this morning, when i got the call this morning, i thought it would be a camper, someone trying to keep warm, gas leak and explosion. As i got more updates, i found out it was intentional. We had no prewarnings at all. What do you make of the timing of this being there are no people on the street at 6 00 in the morning and that it happened with the announcement playing in advance. Yeah. I dont want to speculate. You would think that this person didnt want to harm people, that maybe just wanted to destroy, but were not sure until we get further into the investigation. Chief, you talk about the 911 impact by this. Several cities had 911 system knocked out because of that. Do you think that was the relation, the intention to knock out 911 service . Were not sure now. We are following up. We are aware some services went down, had at t go down a little while, but thats back up now. To say anything more would be speculation. Im going to ask for that to be the question for the chief, ask him to come and give an update. Good evening. Theres a lot of Unanswered Questions that we cant answer now. Some of the things we want to talk about, talk about Public Safety and fire and police, office of emergency management. The things we do operate off the lip method, live safety incidents, proper conservation. Currently now we know we have done a sweep of all of the buildings to make sure we cleared that theres no personnel that are in the buildings, when we have done all of the hazmat sweeps and things you would imagine, if theres a dirty bomb or something of this nature. Now we have search and rescue teams in. That way we can shore up buildings. We have Structural Engineers there to make sure that the buildings are sound enough to be able to enter in and out of them. Again, it is a lot of moving parts and i know theres a lot of questions again that were trying to answer but at this point theres so many moving parts. Again, we just want to take our hats off to all of the First Responders and all especially with the infrastructure in the situation it is, all of the partners we have in local, federal working together to make sure as the man said we are a resilient city and will keep moving. Thank you. Do you have any idea how many people were evacuated . Great question. We are working on that. The way units are designed, we are trying to get an accurate head count. The red cross is partnering with us and we have mta buses set up throughout the city, so if theres anybody displaced, well take them to the East Park Community Center and from there make sure they have a place to stay for tonight or for as long as needed. In the hundreds . I want to say many people, im sorry. I wont put a number to it. We know there are people that are displaced. Chief, can you speak to Structural Integrity of buildings downtown, given the explosion, is that part of the reason theres a curfew the next few days in case anything absolutely. Office of emergency management, we tried to look at the overall view of the city, making sure everything is safe and working together. We know we had one Building Collapse due to the explosion and due to age of the other buildings, then we had water was then displayed throughout the buildings, with the cold weather, we think the Water Department is making sure they have the water shut off, but still the integrity of the buildings are in question. We are trying to make sure we have everybody in place and safety for all personnel. Chief, what building was that collapsed . I dont have the address. Do you know the business inside, residential . It was a building that actually housed, across from the explosion, above, was residential above. I cant give you, im sorry. Thank you. Last question for this evening. I want to thank you for coming out. We will be in touch with you. Bring in andrew mccabe, former Deputy Director of the fbi. We heard the police chief confirm they believe human tissue was found near the blast site, wouldnt say exactly. They said tissue that could be remains, though at this point theyre saying no known fatalities. Andrew, we didnt hear from the fbi at this briefing. Did anything stand out to you from what you heard from the mayor or the police chief . Well, just what you mentioned about the recovery of some presumed human tissue. You dont know where that was picked up. Hard to say whether they can connect that to the rv or not. Thats certainly a possibility. The other thing i heard that was interesting was the chief was talking about what his officers heard when they got on the scene. They heard the announcement coming from the rv, then described it as a countdown, and then music played. And then the countdown started again. Thats a bizarre sequence of announcements coming from the device minutes before it d detonates. The fbi and partners will be looking at each little detail to try to attach some significance to the words that were used, the frequency that they may have been repeated, if there was music playing, what was that music, how can we identify that. They will take a forensic microscope figuratively speaking to every single fact and detail that can identify about this incident. And it will go on for months. The recording which is a female voice, talked to Betsy Williams, a resident that did evacuate, she described it as a Computer Generated female voice. Unclear whether theres any way to trace Something Like that, sort of what programs are used and may be a specific kind of Computer Generated voice, but she also said that there was the shots fired that could have been on the tape or actual shots fired, seems more likely they were on this tape. Then the announcement from the recorded voice for Betsy Williams, saying evacuate now, theres a bomb, a bomb in this vehicle and will explode. And countdown started saying 15 minutes. And then she had driven away at that point and was parked away, waiting for a blast that didnt occur. She estimated might have been as much as 15 minutes, after the 15 minute countdown had ended, then the blast did occur. I dont know if that was intentional or malfunction or why there would be that discrepancy, but it is interesting whether that was intentional or not. Yeah. Really hard to say at this point, right, if there was someone inside the vehicle who detonated this manually, that opens up a whole flood of possibilities, maybe they were having trouble with the equipment, maybe took longer to get things started than they initially planned. If it was set on a timer, you have an automatic device, theres all sorts of opportunities for mistake and error in that as well. The thing that i cokeep coming back to, this block between church and commerce thats of course Second Avenue north is covered with video surveillance. There are so many cameras, even that you can see looking at photos on the internet. They know when the van arrived, they know when it parked on the side of the road. They should have a pretty good idea of the foot traffic in and around the rv, if there was any, or even if anyone is seen getting in or out of the vehicle. My guess is that the investigators obviously know a lot more than we do right now and the fact that were not hearing about that doesnt mean they dont know it, it just may mean theyre running down leads that are better covered covertly and without a lot of attention. They would also need any situation like this, given there was at t had a building on the street, according to one of the reporters on the scene, they asked about lyft, i assume they had an office on the street as well, then there were smaller businesses. Part of the investigation would i assume be contacting all of the businesses, finding out if they had any specific threats against them, any kind of crank letters, any security threats over the last several months or so. Absolutely. And particularly at t. I say that only because it appears that the rv was parked right in front of that very large kind of red brick building which we know belongs to at t. The fbi folks are very familiar with their security counterparts at at t, another Large Telecommunications company. Thats a well established connection. I am confident that they had many conversations today, some of those are among the lines of can you identify for us every employee that works at that facility and any employees that you may have had problems with Security Issues, with other people that maybe arent employed but came to your attention as Security Issues in and around that facility. There are many, many leads that are being tracked downrig right this moment on each of those lines of investigation. At t is the Parent Company of cnn. Back with the eyewitness of the explosion next.

Imagine hanging out with your daughter when chaos breaks out after a huge explosion is in the distance. Get it an eyewitness, david malloy joins me. Thanks for being with us. Sorry it is under these circumstances. You were walking your dog when you saw Police Activity and then heard the recording coming from the rv. What did you see and hear . Okay. Well, i stepped outside and our building is next door to the 21 c hotel, the manager was running around saying he had to evacuate the building, was told to evacuate. I was frazzled, every corner had police cars at it, stopping any kind of traffic. I turned around. Do you know what time . This would have been a couple minutes before the explosion. I think the explosion, my security cameras i think showed it at 6 29, right there. This is a couple minutes before that. I turned around, an officer is walking toward me. I said why do we have to evacuate . Whae whats going on . Right then the bomb went off. His back was to the explosion, i was looking at what was behind him. And were about a half block away from where the explosion was. Anyway i am seeing video, i believe thats you with your dog, is that right . Yeah. Yeah. Thats the black german shepherd. We walk over one street over to a grassy area. Thats where i was headed. And then when he stopped me. After the explosion, all i saw was this huge fireball from my side of the street, the same side that the at t building is move across the street and then up in the sky. I didnt feel any concussion from the explosion. And it was really loud but it hurt my ears. The dog didnt yelp, wasnt anything like that. I wasnt aware what kind of damage this had caused. Immediately he had to escort me back to the building, started to yell for my wife, she was in bed asleep. Blew out our building is an old building, historical era, 1875, it blew out the back windows on our two floors. Blew debris over the bed where my wife was sleeping. You can see the video now inside. Did you hear the voice coming from the rv, the recorded message . I did. I did hear the recording. It wasnt really loud. Honestly, i thought the recording was coming from the police car. It was very official. I didnt notice any accent about it or anything. It was like a professional voice thing. One witness i talked to said it sounded like an automated female voice. To me it sounded male. Sounded like something automated . Sounded professional, yeah. It sounded professional. Really, yeah, it did. Had there ever been any incident in this area . Outside that at t building . Had there ever been protests or anything like that . No, that building, they stay real quiet with that building, theres no windows or anything like that. They try not to draw attention to it. We are two blocks up from lower broadway, and we always wanted to clean up our little area, make it more presentable to tourists but that building was basically untouchable. They didnt want any artwork or anything to draw attention to it or whatever. Are you in your home now . Yes. We are taped off across both sides of the street. Basically we are kind of in a secluded were supposed to stay inside. We are under curfew until sunday at 4 30 in the afternoon. I stepped outside a couple hours ago to ask the fbi permission to walk the dog. Thats kind of where were at. They really dont want us to leave the building, take vehicles or anything. Im glad you and your wife are doing okay. I appreciate you taking time to talk to us. Thank you. Thank you very much. More to come as breaking News Coverage continues. Stay with cnn.

Joining me, cnn Law Enforcement analyst and peter licata for the fbi in new york city. Peter, lets start with you. In terms of we heard from the police chief in nashville as well as the mayor, not a lot of new details. The police chief saying they found tissue that could be human remains near the blast site. No known fatalities. In terms of when you and i last spoke, you talked about different types of explosives, commercial, military, improvised, homemade, and depending what they find, that would lead the investigation in different possible directions. Yes, thats correct. So, you know, obviously if it is commercial or military type explosives, theyre going to start canvassing places that manufacture and store commercial explosives, that would be used in commercial blasting. If it is determined it is improvised or homemade which is the most likely scenario, youll find the majority of bombings that happened in the United States going back to the 90s have been improvised or homemade explosives because theyre regulated in the u. S. That being said, then we go down a different path and a wide path to go down. Theyll be canvassing retailers that sell precursor chemicals, subpoenas for ebay, craigslist, places where other bombers purchased explosives, precursors off the internet. It will take them very deliberate, deep investigative path to determine that. Chief ramsey, this recording really stands out to you. You and i talked a couple hours ago. To have a recording, to have somebody call in, say theres a bomb in place at such and such which has occurred in the past, have you heard of other incidences theres been a bomb that had a recording that went along with it . You know, i havent. Of course, im not a bomb expert but i did listen to one earlier on cnn who mentioned thats the first time they were aware of an actual recording in the vehicle that contained the explosive. Thats unusual. I was listening to chief drake and i agree, the officers did an incredible job. One thing i hoped he would mention is whether the officers were wearing body cameras or not. If they were wearing body cameras, they would have picked up the actual recording on the devices. I know nashville is just getting body cameras, beginning to roll them out. I dont think all of the officers have been outfitted yet. That would be interesting and certainly would be Critical Evidence if they were in fact wearing body cameras. Theres a tape on social media, were not playing it because we havent independently confirmed the authenticity, dont want to put out anything we dont know is real, but the idea of recording with the device, is that something you experienced before . Not me personally but it has happened as of recent and then you have to go back to the 2012 aurora theater shooting that took place by james holmes, a perpetrator that one of the things he did in his apartment that he was targeting First Responders, he knew very well that First Responders would determine that he was in fact the perpetrator. He left a recording inside his Apartment Building in his apartment that had a loop tape on that was set to go off at a specific time that actually had gunshot firing. Therefore First Responders were coming up to his door thinking there would be gunshots going in and they would go ahead and have to kick the door in which would set off a series of victim activated devices to First Responders, it has happened before. Thats interesting. Thats one of the things about the alleged gunshots that were heard by eyewitnesses that called 911 which is what brought police to the scene. It is not clear there actually were shots, it very well could have been part of the recording. It could have been part of that recording, it could have been small pirate tech nick devices being thrown. A lot of times, depending on the street and echoing, canyon type style, firecrackers, pyrotechnics especially at 6 00 in the morning can sound like gunshots as well. Peter, is there any sense, clearly someone drove the vehicle, the surveillance camera footage picture that was released was taken at 1 22 00 a. M. Clearly someone drove it to the location where it eventually exploded about five hours later. Is there any way to tell whether something is detonated remotely or detonated on scene or is that just await the investigation and, i mean, you can only know that by looking at what debris is left from the device . Thats going to be clear in two factors. Thats going to be the internal investigation that we talked about. Its going to be the parts of it, the componentry of the bomb that Crime Scene Team members find will determine whether or not it was initiated command or remotely or initiated via time. Those items, those components dont just vaporize, theyre there. They will be found. It may take a few days but they will be found. It will also go to the fact that even if theyre not necessarily found quickly enough in the crime scene, if Law Enforcement determines the subject, viable subject through deep dives into social media, through cell phone coverage, through normal investigations, as search warrants are generated, parts of that device are generally going to be found wherever the device was built, house, apartment, shed, anywhere. Those things are going to be found and compared to what they find crime scene versus where the device was constructed. Appreciate both of your expertise. Thank you so much.

Has the president said anything on this incident . Reporter anderson, we havent heard from the president directly on this explosion that took place in nashville. We got a statement from the white house confirming the president was briefed on the incident. This is a statement from the Deputy White House press secretary. President trump has been briefed on the explosion in nashville, tennessee and will continue to receive regular updates. The president is grateful for the incredible First Responders and is praying for those injured. We were hoping to see the president on camera this evening. He was scheduled to have a phone call teleconference with the troops as he typically does on christmas day. Usually he allows cameras, but today hes not allowing the news media in and the white house gave us a lid, meaning were not expecting to see or hear from the president today. What do we know about the president signing or not signing the Coronavirus Relief bill. Reporter we know that piece of legislation was flown down from washington yesterday and it is now at maralago. The question remains as to whether the president will actually move forward and sign that legislation. What is remarkable, anderson is the president since making that threat no veto this legislation hasnt been on the phone with members of congressional leadership or meeting with advisers to try to find a way to get the stimulus checks to americans. Instead the president has been golfing and tweeting anger ri at Senate Republicans as well as continuing to complain about this 600 checks versus the 2000 amount he would have liked to seen. But as far as doing anything to get that done, missing in action. Is it clear how long he was golfing for today . We know he was at his golf club for about five hours this morning. We know he was golfing. Cant confirm the exact amount of time on the greens but he spent a large chunk of his day there as he did yesterday as well. All right. Jeremy diamond, appreciate it. I want to bring in Josh Campbell to talk about the investigation ongoing in nashville. Josh, we heard from the chief of police there saying they did find tissue that could be human remains, but as of yet, there are no known fatalities from the blast. Yeah. Thats right. We dont know based on our own reporting we were hearing from sources the same. They found possible human remains that were taken to the medical Examiners Office for analysis. We dont know how close to the vehicle that these tissue parts were found. Whether they were inside. Again, this thing was obliterated as the explosion went off nature is what officials are trying to determine as they do the testing. Again, we dont know if this was the perpetrator or possibly an innocent victim in the location. Its harder to think it would be an innocent victim just because of the work of Police Officers down there and trying to get everybody away from that scene as a recap for folks, Police Showed up to a call of sounds of gunfire. They heard a recorded announcement coming out of this rv saying a bomb would detonate in 15 minutes and they moved quickly to try to move people out of that area to warn them. The police chief there saying officers saved lives today. Now, we also know that this Investigation Continues despite the fact that they have this possible tissue theyre trying to identify the person. Theyre trying to identify all the possible cc tv footage they could find and other digital evidence. One thing we heard confirming our earlier reporting is there were no known threats ahead of the incident. We heard from our sources there was nothing that authorities had heard about a possible attack or any types of threats on or before christmas. Were also told from Law Enforcement sources there was no chatter indicating any type of impending attack. This caught authorities completely by surprise. They are saying, the police chief is saying. Its just a typical investigative work theyre having to do and scouring the area to try to piece together who the perpetrator was.
