Expected to be underway any moment now. Residence as you can imagine in Chester County are being asked to be on high alert as hundreds of Police Officers have descended on the area. Following every lead possible to track down the convicted killer. Authorities say Danelo Cavalcante was last spotted over the weekend when he stole a dairy delivery van and apparently has changed his appearance, john. John photos you can see here captured on a doorbell camera, clean shaven and in different clothes, and tried to contact acquaintances in the area. Sandra nate foy is live in the area. About to get an update. As we wait for that, the investigation continues. Tactical teams are spread out. They dont have enough intel as far as where he is to have a defined Search Perimeter, but authorities are spread out and following up on all tips. Sandra the News Conference is underway. As i told you yesterday, the investigation has taken a change in direction in terms of the allocation of resources and daily focus of investigators. Moved from a containment model to one which involves a variety of investigative resources and additionally, the public can expect a Law Enforcement presence in the area of East Nantmill Township where the van was recovered and other areas of northern Chester County. No need for alarm when the resources are observed. If a possible threat develops, we will use the reverse 911 system to notify affected residents. I would like to address a message to anyone who may have offered assistance or is contemplating assisting cavalcante in any way. We will prosecute you fully for those actions. Alternatively i would suggest that you are in position to help facilitate the safe capture of cavalcante. If you choose to assist us you could be eligible for some or all of the reward that has been offered for cavalcantes capture. As a matter of fact, im announcing Chester County has increased the amount of reward they are offering by another 5,000. That brings the total reward offered up to 25,000 for information that leads to the capture of cavalcante. We remain concerned that cavalcante will attempt to steal another vehicle to facilitate his escape. As a reminder, we ask for the publics help by familiarizing themselves with the updated photographs and description of cavalcante, to check Security Cameras they have and call us immediately if they believe they may have seen him. Again, we ask residents to please secure homes, outbuildings and vehicles. It is imperative that anyone with information about cavalcante contact us immediately so that we may act on that information in a timely manner. Anyone with information is asked to call our tip line at 7175622987. 7175622987. I know this is an extremely stressful time for the community. We are doing Everything Possible to bring this to a successful resolution as quickly as possible. I and all of us working on this every day appreciate all of the support that all of you have given. Thank you very much for that support. And at this time we will be happy to take any questions you might have. Do you have evidence that someone has tried to help him or is that why you arrested the sister . The sister is an overstay, and she chose not to assist and because of being in an overstay status is doing to a deportation hearing. He wanted her to help she has not. She has not assisted. Did she help anybody else trying to help him, you put a warning out there. Do you have people you know of who did try to help him . Im cautioning People Preemptively and yes, we are monitoring we are monitoring for any possible help in a variety of ways, and so what i will tell you is that if we detect assistance that will be prosecuted. Im not going to say anything further than that in terms of who may or may not have. What im going to say is as a warning, you will be prosecuted. There is an Alternative Path to try and assist with his safe capture. Timeline here [indiscernible] he shows up at these homes 10 30 saturday night, but yet people in the neighborhood say police were not making checks until well after 2 00 in the morning. Is there any kind of delay here so the people [indiscernible] did not we were not notified until well after midnight of the sightings. Two hours after he shows up at this house and has a conversation. At least two hours. 911 with the call from the family on the ring doorbell camera, any issues can you walk us through the entire sequence . Im not aware of any issues with the 911 testimony and ive laid out what the timeline was and what i will tell you is the individual so for example, the one was not home at the time. They were utilizing the doorbell to speak with him. They arrived home some time later, reviewed the video, and contacted local police. Whatever occurred there, we were not a part of it. We received the notice and i gave you the time yesterday, some time around 12 30, as i recall, so after midnight when we received the notice and our investigaters then began working on that video. [indiscernible] heavy police presence, knocking on doors in that neighborhood as well. The only two we had reports he communicated with anyone. Lieutenant colonel, at this point, any other visual confirmed sightings since the doorbell [indiscernible] there have not. You have reason to believe he vanished Without A Trace. Of course he has not vanished Without A Trace and yes, i believe he is in pennsylvania. How many Law Enforcement personnel do you have working on this now, additional total right now is still probably hovering around 300 mark and yes, we have brought in Additional Resources so we are switching some out. I described yesterday that today, as a matter of fact, we had planned a major push, so more uniformed resources, tactical teams, very large number of tactical teams and other assets that would have been utilized. We have instead replaced some of those resources, certainly not all, with other investigative resources because as i told you, the investigation has shifted and so not only the state police but our federal partners as well have brought in Additional Resources that we believe will be useful going forward. We collectively conduct Fugitive Investigations every day of the year, and so this one is a little different scale, but its the type of investigation each of our agencies works on a very regular basis and we are adjusting with the resources we believe. Why arent there assets at these Acquaintances Homes before he made this appearance and are you doing that moving forward in this investigation . When you say Acquaintances Homes, these people had not, to my knowledge, had any contact with cavalcante for years. So they were not friends, they were prior work associates, for example, and they were not people that we would have expected or that we would have known even to contact again from the distant past. Any thoughts on raising the reward to 50,000, 100,000, to help bring him to justice sooner rather than later . Right now announcing the reward is 25,000, i believe thats a lot of money. I am hard pressed to believe that someone is sitting out there with information saying 25,000 is not enough. I suppose well consider things as we go forward whether that will increase or not. But for now, seems to be a reasonable amount. With no defined area to search, are you 100 reliant on public tips in order to find him . No. A lot of reports or rumors that cavalcantes sister was seen near the Search Perimeter [indiscernible] ive heard those report. Her arrest was because she is an overstay, that was a process that would play out for anyone in her same circumstance, and what i would say is she has she has failed to cooperate and so there was no value in Law Enforcement keeping her here at this point. Communications with the sister and acquaintances, what do you know about the resources he may have, cell phone, money, food, what is he asking these people if he can get in contact, what intelligence have you gathered i dont want to talk specifically what he may or may not have or what hes looking for. All pieces of our investigation. But i think its again fair to say what ive said all along, he needs additional help, he Needs Resources for the long run and he is seeking those. [indiscernible] we dont have a defined search area at this point. We are considering and certainly acting on and investigating any piece of information or tip that we receive. And so we follow those pieces of investigation pieces of information with our investigation as we have done from the very start regardless of where they are. There are areas that i describe, for example, in East Nantonville Township that may have more focus on some of our resources that are more visible but again, that certainly is not a limiter at all for Everything Else that we are doing. Speaking generally, why do you still believe hes in pennsylvania . Because i have no reason to believe he is not. I dont know he has the resources to get out of pennsylvania and again, other pieces of information that we have generated within this Information Lead me to believe that he is still here. Does he have any other Family Members here that he has contacted . Im not going to talk about who we have contacted. He does he does still have some family and friends in the area, we are aware of those. Why was his sister now. She previously testified at his trial in cooperation with the prosecution, i assume her status was known earlier in august, why arrest her this week. From my perspective, i dont have anything to do with the removal process, there is no reason for me to try to interfere in that process because she serves no value to the investigation and she potentially could provide assistance. Im not confident that she would not in the future if we let her out there. Can you talk about what led to the activity we saw last night, you said since the doorbell camera no confirmed sightings. Can you expand on that a bit . We continue to receive a significant number of tips and so again, we will follow up on all of those. We have things that we are doing proactively and so you may see some activity as a result of that. We have, you know, and i said there are other things that may not be so obvious that you wont see that are going on as well. Law enforcement [indiscernible] considering rural area and talked yesterday how he was able to stay outside of the perimeter. Similar challenges in terms of the search efforts. Very similar challenges to what we have faced previously to this point. Unfortunately we dont have a Containment Area right now, so thats another concern, another challenge. But again, we are working through all of that, trying to pull together pieces of information so we can narrow and the search area and ultimately use those tools to be able to capture him. How did he slip out of the previous Search Perimeter . As i said yesterday, i dont have a definitive answer on that. I have theories of how it happened and i have theories because im aware of the weaknesses in there. No perimeter is 100 secure. Its not a wall, it doesnt have a ceiling, all the things you might normally use if you are trying to contain someone. We use the human element, we use technology and so forth to be able to secure the perimeter as best we can. Im aware some of the weaknesses. Longwood garden presented some unique challenges and i believe he exploited the challenges. Do you believe mistakes were made that allowed him to get out of the perimeter . Without knowing specifically what happened, i had concerns, i knew there were weaknesses in the perimeter. It was a very strong perimeter as far as perimeters go but there are always weaknesses and that place posed unique challenges. Perhaps when this is over i can talk about some of those, it was a very difficult place to try and secure. More of a challenge, Lieutenant Colonel, you have a far bigger area and no perimeter and you really have not gotten [indiscernible] sir, we conduct Fugitive Investigations every day of the year across this commonwealth as do our partners that are standing here with me. Each one of them poses a challenge. We are most often very successful in those, most dont lead to a protracted search like this. I am confident that using all of those resources we will ultimately bring this one to a you can successful conclusion as well. September 11th, any thoughts on the Men And Women, [indiscernible] certainly today is a day of remembrance and our thoughts and prayers go out to the victims of 9 11. But what i would tell you is the Men And Women that are working here on this investigation are not pausing or taking a break, they are actively working and doing their jobs because thats what people expect them to do. Question for rob clark, as far as marshals are investigating, you mentioned it was like a tactical game of cat and mouse. What changes now for your guys that are out there . Thats a good question, so in the beginning we were prepping here for the short game. We had a Tactical Response prepared in a certain area and while that response is being prepared we had a group of investigators from the u. S. Marshal service here, some of the brightest minds in the agency, having a Contingency Plan of who we were going to do should he break perimeter or if he was outside that perimeter. So we had proactively planned for this and i would say, you know, we have our preoperational planning, tactical resources, Technical Resources were brought here and now planning for the long game. The search in the woods was to cavalcantes advantage. He was in an eight square mile area with very difficult terrain, difficult to get to and there were some weaknesses in the perimeter. I think the Incident Command here was great setting up the perimeter, bringing in the resources and doing the absolute best we could. We had, i think, over 200 Law Enforcement officers in or around that perimeter. But now we are going to prepare for the long game and the long game is what we do best, u. S. Marshal service, like the colonel said, does Fugitive Investigations every day. This is a manhunt. And what it means to us, its a longer Fugitive Investigation with more resources. So we are prepared. Cavalcante playing war game now . Cavalcante i think the advantage has switched before. Before testifies Advantage Cavalcante taking the tactical hide and seek in the woods now advantage Law Enforcement because hes in an urban setting. Thats what our investigators do best and force multiplied by the other state and federal agencies so i believe the advantage has switched to Law Enforcement. What is it you do in this long game, in this urban setting . What change [indiscernible] a lot of different investigative techniques, i dont want to specify exactly what they are, but we are going to do the same thing we do every day in the city of philadelphia. We are going to go out, we are going to talk to people, utilize the assets of the u. S. Marshal service. Certain investigative techniques i dont want to reveal, but we are going to try to stay one step ahead. You called this the perimeter, is that based on resources or geographical first part of your question. You said there was some weaknesses in the perimeter. Based on resources or was that more maybe i misspoke, not weaknesses, but challenges in the perimeter. Lieutenant colonel was accurate. A massive tunnel system, a lot of ravines, very thick vegetation. You call it the long game, some people may think you wont expect to catch him soon. No, we expect to catch him as soon as possible but will not put the ducks in a row and say we are going to have him by this thursday, we are going to plan for a long investigation because we dont want to get caught planning for immediate arrest and then not prepared later down the line. Different that hes very close to potentially another park, another vast area, are you focusing on nature where he was able to hide in the area versus where other routes there are cameras everywhere, and easier to find him with a cell phone or debit card. Do you think hes in the woods still . Like the colonel said, we are investigating that area in East Nantmeal until something suggests hes not in the area, we will continue to investigate there. I reiterate the message from the colonel to the public, please be vigilant in the areas we are searching, make sure the doors are locked, car keys are secured in your residence, report anything suspicious to Law Enforcement and if you have tips, call them in. We would like to investigate 100 bad tips rather than miss that one good thats not called in. Did he try to secure another vehicle since dumping the van . Not that we are aware of. You talk about protracted search, comes to mind, ten years ago, 40 some days. What are some of the similarities and differences between the two searches . Question better for the colonel. Well, what i would tell you is every search has its challenges. Some of the similarities, large search area, very difficult to know exactly where he was, and i would tell you that almost nine years to the day some of you all were standing with me in that area up there. And some of these same q
