Southwest of austin. There was an explosion here on a Conveyor Belt. A medium sized package. We have heard reports that it was sent by somebody in austin, to somebody in austin, the atf has not yet confirmed that to us. Then shortly after 6 00 a. M. This morning, a call went into austin pd of a suspicious package at another fedex sorting facility up near the austin airport. No word on whether that turned out to be a device or just a suspicious package. But as you mentioned, there has been a spree of bombings in austin since march 2nd. Three parcels were left on peoples doorsteps, detonated, killing two people, injuring one woman, and then sunday night there was a trip wire that triggered another device injuring two men. So this is an ever changing investigation. Initially the police, the authorities, the 500 federal agents down here, were looking for somebody hand delivering packages to homes. Then mo changed. There was the trip wire. And now these packages apparently sent through fedex. Nick watt, thank you so much. I want to bring in cnn Law Enforcement analyst and former u. S. Marshal art roderick and in new york, cnn Law Enforcement analyst and former supervisory special agent at the fbi, James Galliano. This is now the third different tactic that we have seen. This is a bomb that was shipped, it was on a Conveyor Belt. It was filled with shrapnel. What does that tell you about the suspect here . Sure, we know the bomb e expanded his portfolio. Started out with delivering packages. Did it by himself, with an accomplice, werent shipped anywhere. The next device, the fourth one i believe had a trip wire, which was the switch that ignited it, a target of opportunity so we know he wasnt targeting anyone in particular. And now this last one that exploded just after midnight, appears to have been shipped to that facility or it was hand delivered to that facility. These are three separate delivery systems. Now, when it comes to bombs, every bomber has his own signature. And the device is basically made up of four components, a power source, which can be a battery, you have an initiator which can be a blasting cap, you have the actual explosives and then the shrapnel that could be part of it. And then you have the switch. The issue here is with bombs, which makes it so frightening, is the lethality of them. Most people that come in contact with a bomb, most casualties come out of the overpressure that comes out of it. Then if there is shrapnel introduced like were hearing this one may have had nails or nuts and bolts in it, that can create a problem. And the last thing is the thermal effect. This has authorities on just perplexed from the sense of it looks like the frequency and raed bity of the attacks different from the unabomber back in the late 70s and early 90s who essentially mailed 16 packages within a 17year span. We now could possibly have six connected devices and packages within a twoweek period. It is so many. Because i think people are think back to the unabomber. This is six packages in this short span with different types of tactics. Does that tell you anything about how advanced the planning may have been or some sort of experience that this suspect may have . Thats exactly what it tells me. But there is also three things complicating this whole investigation. Number one is, you know, the method of operation has changed. Which definitely makes it a lot more difficult. There is no number two, no connection between the perpetrator and the victims. Thats also very difficult. That we know of or sounds like definitely theres not. At this point, you know, we sort of have it started off where it could have been targeted and then we have this random trip wire explosive that was set up a couple of days ago. So this makes it a lot more difficult for any crime to be solved when there is no connection between the perpetrator and the victim. They must assume, authorities, that there is a connection between thats the first thing theyre going to consider, right . Or theyre going to try to hypothesis check that, are there connections between the different kinds of bombings. What would your expectation be . Thats the big part here, connect these last two explosives at the fedex facilities with the other four explosives and this is the other issue, the third issue that complicates this investigation would be a copycat issue, somebody else doing this now, trying to glom to this press occurring with the series of bombings going on around the austin neighborhoods. Why have the authorities not labeled the bombings as terrorism. This is domestic, but it seems clear that this is terrorism. This new type, where theyre not being delivered but could just be targets of opportunity that theyre victim activated. You step on a trip wire, and it sets it off, or just gets it explodes or detonates while at a facility, just being handled. Authorities are very careful about that for a couple of reasons. First is, terrorism has a very distinct definition. It is violence or intimidation in the pursuit of political or social goals. We have to get into the mind set of the bomber here. Thats very difficult to do at this early stage. Why is that . Well, crime scenes are difficult to process. Post blast analysis involves harvesting evidence that oftentimes is destroyed in the blast. The other consideration here is being careful we dont want to get out ahead of our skis, but initially i believe the first three packages that were delivered were on the east side of austin. They were delivered to homes of people of color or latinos. The issues that they had we immediately us isuspected a potential hate crime. Then when it moved to the west side, into a different neighborhood, and it was basically victim activated, that changed. Were going to see the behavioral analysis, the folks that put together psychological profiles go through this with a fine toothed comb and i expect that the information we get out of this upcoming presser will be critical to helping steer us toward a motive. Yeah, we are awaiting that press conference, i should say, we expect it is going to start any moment, well be taking that live as soon as it does begin. This was shipped through fedex. So that could provide some clues or maybe it would not. Everything just off the top of my head, im thinking if you have to walk into a facility, would there be cameras, what type of payment was used, all of these things. What would you be looking for . Hopefully there is some forensics on that particular package, dna or fingerprints. But i think thats the key to actually solving this case. Three things that will solve this case, going to be the painstaking review of all of the video in these particular areas, whether it is at the fedex facility, where this was shot from, or from household security cameras or business cameras around the area. Or someone even remembering the person, right, who mails i think of i think of, for instance, Oklahoma City bombing and it was someone actually remembering what someone looked like as they made purchases that helped them track down Timothy Mcveigh and his the other interesting thing here is this individual is watching all these pressers, press conferences, watching the news and changing his method of operation. I want to go to brian todd. Brian todd, tell us what youre hearing as we await this press conference. Right, were hearing the latest on the casualties is three people injured, all of them students here at Great Mills High School in great mills, maryland, about an hour and 45 minutes south of washington, d. C. According to st. Marys county sheriff, tim cameron, the shooter entered the school early this morning, confronted another student, a female, shot her, shot another student, and then a School Resource officer and engaged the shooter and ended the threat. The threat was contained very quickly, were told, by the sheriff, we are expecting a briefing later on to find out more information about the nature of the shooting, the weapon used, and any possible relationship between the shooter and the victims. Thats what we dont know at this hour. But a big part of what happened today, brianna, is that School Resource officer, according to the sheriff, kwuk lquickly engae shooter and ended the threat here. Behind us, a constant flurry of police activity, but also school buses have been escorting students out of here, to nearby leonard town high school. Just north of here on great mills road. They have been the Sheriff Deputies and others escorting bus loads of students where there say staging area where they will meet their parents. Brian todd, im so sorry to interrupt you, we have to go to texas where a press conference has begun on the package bombings that we have seen there. The safety of the employees and the public has been, is and remains our principle focus. Pertinent to the focus on Public Safety, the city of schertz is engaged and is working in cooperation with the fbi and the atf. Here with me this morning are my chief of Police Michael hansen, assistant special agent in charge james smith from the fbi, and assistant special agent in charge, frank ortega from the bureau of alcohol, tobacco, firearms and explosives. At this time, i would like to recognize our chief of Police Michael hansen who will provide you with some additional information. Chief . Thank you. Good morning. At approximately 12 25 this morning, an explosion was called in to the Police Department. It occurred at the facility at 9935 duer lane. Members of the schertz police, fire and ems responded and determined that in fact an explosion had occurred. Shortly thereafter, members of the San Antonio Police department bomb unit, the bureau of alcohol, tobacco, firearms and explosives, and the fbi arrived as well. A package had been traveling along the automated conveyor when it had exploded. One employee that was standing near the explosion later complained of wringing in the ears, she was treated and released. We were very fortunate that there were no injuries. It is very early in the investigation, obviously. But were confident that neither this facility, nor any location in the schertz area, was a target. With that said, need to reiterate the message that we heard so often recently that if you have a package that was not expected, if you are suspicious of the return address, if you come across any suspicious object, do not touch it, do not move it, but contact 911. We should take this opportunity to thank the assistance provided by the fbi, the batf, Texas Department of Public Safety, the San Antonio Police department, the Bexar County Sheriffs Office and the resources that have been provided by the southwest, texas, regional Advisory Counsel and the bcfs emergency management. Ill open it for questions. [ inaudible question ] cant go into the details of the package. Still under investigation. We just arrived pretty much and were entering the building as we speak. Supposedly from austin. Was it labeled . Cant say where the package was destined for. Were still under investigation. Could this be the work of a copycat, because it was sent directly to thats what were working on right now. Were trying to understand what actually happened. Were trying to search through the evidence and let the evidence take us to where we need to go. [ inaudible question ] were still looking into it. Were still early on. It happened late last night. And we arrived early in the morning. So were still working on it. Do you suspect this is connected to the serial bomber in austin . We do not know at this point right now. Im sorry . Can you confirm the package had nails and shrapnel . I cant confirm that right now. How do you know this wasnt meant for somebody right here . We cant compare them. We just entered the building recently. We have to make sure the building is safe before we can go in. So were still at the early stages. How do you know this was not meant for someone here in schertz . We cant confirm that right now. We just entered the building. Just said that it wasnt targeted for anyone here. We just entered the building. Were trying to understand that right now. But right now we have no indications that there is any issues or threats to the public here in schertz. Can you tell us the size of the package, if there is any evidence for you to actually gather . I cant go into the details of that now. Is there anything new you can add . It is still an Ongoing Investigation and we cant provide that information at this time. Are there employees in the facility still . Are they kept there . Are they released . All the precautions have been taken, necessary precautions have been taken. And the right now investigators are conducting their investigation. [ inaudible question ] im sorry, can you repeat that . [ inaudible question ] were working with various Delivery Companies now with the Ongoing Investigation. They have security procedures and protocols. Theyre doing the normal steps with security and protocols, but we are working with them on the regular packages throughout the day. Is this fedex facility offline right now . Is this fedex Facility Operating in any way . Do people have to wait for their actages packages to come . Were working with the Delivery Company about the packages in there. We just entered the building, so the building has been evacuated. We are ensuring that it is safe to go forward. What can you tell us can you tell people who may be concerned that it may be connected and theyre genuinely scared. We go from austin to northwest san antonio. What can you tell people . This is a very fluid investigation and we want the general public to know that their safety is our number one priority.

Were working hand and hand with our fbi partners, state and local partners, we have we have been working around the clock. Again, the Public Safety is our number one priority. And we are providing all the resources that we can to finally find some the person or individuals responsible for this. You confident youll be able to pull the name on the package . Again, we cant go into that right now. I understand. Were trying to search through the evidence. Were at the early stages of this partilar event here . Surveillance video what kind of evidence do you have now . Cant go into the evidence we do have. But we have just approached this building. Were only three or four hours into this. First priority was to remembend this building safe so they can gather the evidence. Were still were going to be here for a little while. Anything else going on in the facility . We have not done i search yet. What about the one at the facility fedex in austin by the airport . Is that connected at all . Im unaware of that. There is agents there too. You are here, there are agents also at fedex facilities back in austin. Why are you there . I dont know why were there. Were asking people not to come here, were still a crime scene. Were still searching the one more question. Were still searching the packages to ensure there is no other devices there. So were asking just people be patient and if they know of something, definitely call your local fbi, local atf or local Police Department and report it. We need the publics help right now. [ inaudible question ] youd have to contact fedex on that one. What kind of damage is there inside . We just dont know right now. What do you know . Youre giving us a whole bunch of we dont know.

And were following all leads that we received, thats why we encourage the general public to help us out and provide any information that they may have by again calling our tip line. One last question, please. One at a time, please . This is an Ongoing Investigation. I cant get into the details of that right now. All right, we are listening to this press conference. Not too far outside of san antonio, texas, about the package bombs that have been exploded, that have exploded. Last night one on a Conveyor Belt at a fedex processing facility. That followed an explosion from a trip wire, just before that. And then package bombs that we had seen in the austin area. I want to bring back cnn Law Enforcement analyst and former u. S. Marshal art roderick in new york, cnn Law Enforcement analyst and former supervisory special agent at the fbi James Galliano with us. If you live in this area, this was not necessarily a comforting press conference for you. As you are looking at the authorities answer, all of these questions, it becomes so clear this is an investigation that is expanding as the methods of the explosions are expanding, that arent even necessarily tied together by authorities at this point. Were not to that point where things are contracting, where you have a sense that Law Enforcement is really narrowing in on the cause here. Yeah. Obviously there wasnt a lot of information coming out here, the fbi just arrived on the s
