Our coverage here continues. Our breaking News Coverage with my partner anderson cooper. Let me hand it off to you, anderson. Viewers who are just tuning in, these are live pictures from bowdoin, maine, the home of a man Authorities Say murdered 18 people in two locations in the nearby City Of Lewiston yesterday evening, the countrys Deadliest Mass Shooting this year. Police and fbi agents went to this home earlier today, returned there in force a short time ago. In the last 45 minutes or so, if youve been watching, they have been heard asking at least one person to, quote, come out with your hands up. Cnns brian todd is on the scene for us, as is shimon prokupecz. Lets go to brian. Lets start off with you. Explain what you have been seeing for those who are just joining us and what assets that you can say are on the ground. Well, anderson, for the more than past hour, we have been here while kind of this influx of Law Enforcement just kind of poured into this area right in front of the house, right in front. They had been here earlier, then they had left. And then about an hour ago, they poured several vehicles and personnel and air assets back here, and basically set up camp in front of the house with a loudspeaker and a spotlight. And you can see the spotlight now kind of shifting around, either at, rite on the house or just around it. They could also be using the spotlight we believe to check areas on the sides of the house, because that seems to be what they have done. Actually, there was very continuous dialogue. It was a oneway dialogue, but it was a Law Enforcement officer on a bullhorn while the spotlight was trained on the front of the house saying commands like come out with your hands up, youre under arrest, come out with nothing in your hands, we dont want anyone else to get hurt. We know this could be intimidating for you, but we want you to come out and follow our instructions, follow our commands to walk to the front of the truck. Im not sure what truck they were referring to, but they repeatedly asked whoever might be inside to walk to the front of a truck in the driveway. But i have to tell you, anderson, for the last im kind of calculating now 35 to 40 minutes, that dialogue has gone completely silent. We have heard no commands. We have seen these assets on the ground shifting around, vehicles shifting, air assets like drones, helicopters just kind of shifting all around. That spotlight continues to shift. And, you know, they seem to be very methodical in the way theyre going about this. There is not a you can see the spotlight there probing around a tree at the front of the property. Brian, lets point out what we do not know. Its almost as important as what we do know in this time. You talk about a dialogue. If there is a dialogue, as far as we know, it has been one way. They dont know for sure there is somebody in this house, correct . That is correct, anderson. From every indication that myself and my colleagues who have working sources have gotten, they do not know or at least if they know, they dont want to reveal that. It has not been revealed that they know he is there, is what i can say. I have to say there has been no i guess rapid or Jerky Movement of anything here. Theyve been very methodical in moving assets around, moving vehicles around, repositioning the spotlight. Moving drones and other things. And they seemed i can also tell you by the way that the lights are no longer flashing. We can see police lights, but theyre not flashing anymore. And yes, to reiterate, the dialogue has been oneway. There is no indication that anyone on The Other Side has been talking to them. Also just want to remind our viewers we are not discussing any tactical moves that any of our reporters may witness over the course of this. Law enforcement asked reporters on the scene to turn off their lights. We have done that, obviously, as well. So the dark what you are seeing is what our people on the ground are seeing as well. But were not going to go into details about any movements that we may witness in any level of detail. Shimon prokupecz is also on the scene. We have two different angles on this from two different teams on the ground. Shimon, talk a little bit about what we know about this suspect and what we know about this location that they are at. Right. So this is believed to be one of the residences of the home of the suspect. And at this point, based on the way Law Enforcement is behaving, the way theyre conducting is they dont feel that there is any kind of imminent danger, right. They dont believe that there are any hostages inside. They dont believe anyone inside, at least at this point just on the way their posture and what theyre doing, theyre not even 100 certain that there is even anyone inside. And theyre certainly not certain that it is a suspect. But everything that were seeing here is to a high degree just precautions, because they know if this is the suspect, theyre dealing with a potentially very dangerous situation, someone who is trained, someone who perhaps will put up a fight. Right now for them its about also protecting themselves. So were seeing all of these heavy vehicles here where they can protect themselves. Theyre heavily arm as well. And theyre wearing heavy body armor. Weve seen some other equipment, drones in the air, helicopters. So theyre able to monitor a lot of whats going on around the home from the air. And it seems theyre really operating right now kind of in the dark, right. Everything is very dark. Weve seen some lights, red lights where theyre working. And theyre support of kind of staying back. It appears from this angle for this to develop. And the state Police Issued a statement saying theyre not certain that that the suspect is inside, that they were doing a Search Warrant here. And all of this is just part of the measures they take, precautionary measures that they take when they execute Search Warrants. The other thing what our colleague evan perez was told is something, Law Enforcement picked up something inside this area, inside one of these homes which prompted all of this, this response. Remember, Law Enforcement was here earlier. They were doing the Search Warrant. They sort of left and they came back. But right now what were seeing is its really intense high drama of the Law Enforcement officials here standing back, allowing this to play out, being very careful. Obviously being very concerned over their safety. The media, just so the viewers know, we are fairly back. We are far back from the home. We are far back from the Law Enforcement that is all around us. We have officers standing around as well that we can see here in the street monitoring the situation. Right now were in a sort of wait and see situation and see how this develops. There is a helicopter over us. Were seeing now some Law Enforcement officials walking. Its unclear if theyre getting to their vehicles, anderson. But were seeing drones in the air. Different equipment that theyre using to keep an eye on things as they develop here. Andrew mccabe, with your experience with the fbi, they certainly have time on their side here. I mean, if this is the location that they feel that they have control of the perimeter of, there is is there is there a clock for them . Not really, anderson. Its you know, if they were confident that there was someone inside and maybe that there was a danger of hostages or others getting hurt, you know, you might want to take advantage of the element of surprise in your approach to the residence. And in a situation like that, there is more of an urgency. But thats clearly not the case here. There is they have forsaken any element of surprise. Theyve been yelling at the house for quite some time. So what youre seeing here is a very slow and steady escalation of technique. They start with the safest, cleanest, lowest risk thing to do, and that is to pull up, stand behind your armored vehicles, and announce your presence and demand some sort of compliance. Whether you are confident there is someone in the building or not, you would always do that first. It seems that that technique has exhausted its relevance here, and they seem to be repositioning now to step on to take next steps. Which could involve things like sending drones up. Weve seen some drones in the air already, sending drones to get a look not the windows to try to develop more intelligence about who or what may be going on inside. You could send a you could breach an entrance and send in a robot to increase that intelligence collection with video capability. The robots can climb stairs. They can open doors. They can do all sorts of things. You can escalate further into sending a dog in. Typically thats not done until you are very confident that there is a barricaded subject, and you know where they are in the residence. And then of course the last step is a dynamic entry of s. W. A. T. Operators who are prepared to go in there and take someone out. We have really no reason at this point we cant confidently say that there is someone in this location. And its very possible that the team doesnt know the answer to that question either. Theyre going to go through this process to try to figure that out in the safest way possible. It is interesting, andrew, that there were obviously officers at this location previously, and presumably did not find anything. And yet returned. Yeah, thats really confounding. There is a number of possibilities here. It could be that they received information from a neighbor, a passerby, some sort of tip that alerted them to movement on the property or something that looked like somebody had been inside. Its always possible when you leave a property if you dont continue to secure it, the subject could have returned to the property after they left. Its also possible its not common, but it does happen, anderson, that well have a Tactical Team search a location, and the perpetrator hides themselves inside. Remember in 2017, there was a manhunt for an individual in a National Park area. We had swat teams from springfield and Chicago Division helping out. They approached what they thought was an abandoned Hunting Cabin in the middle of the woods. The chicago s. W. A. T. Team searched the entire structure, found nothing. And then as a last step, looked into a crawl space in the attic, and as they removed the panel exposing the crawl space, they took incoming fire from the subject. We had a few folks who were severely injured. So sometimes perpetrators subjects will hide in a residence as its being searched, and its possible to overlook them. It could have happened here. We dont know. But you to keep all these possibilities in your head at this point. Circumstances given what we know about the suspect, what points in this persons history stand out to you . Well, there are a number of things about his personality, and i think the first thing that strikes me is that its very likely that if he is inside the house, he views this as a nowin situation. And based on what he has done over the last 24, 36 hours, his life as he knows it is 100 completely over. And so his outlook on whether this turns out well or doesnt turn out well doesnt really make any difference. Then you compound that with Mental Health issues. You compound that with stress. You compound that with whether or not he may be he could be using alcohol or drugs. All of that can really make a big difference. But the outlook right now and how he views this situation is going to be in a very nihilistic way. Brian todd, what have you been witnessing as weve been talking . Well, anderson, what i can tell you is that the spotlight, as crew can probably see has shifted back to the front of the house. But we have also seen Law Enforcement vehicles, several of them really, depart the scene. Now there are Law Enforcement vehicles still there, and there are still assets being moved around on the ground. But in the meantime, we have just gotten an email from the Public Information officer for the Maine Department of Public Safety describing what is happening here. And ill read to it you in part. Regarding those announcements on the loudspeaker that we heard, the commands of come out with your hands up, this person says, this is from the Public Information department from the Maine Department of Public Safety. The announcements that are being heard over the loud speaker are standard announcements when executing a warrant to ensure the safety of all involved. It is unknown whether robert card is in any of the homes Law Enforcement will search. Law enforcement officials are simply doing their Due Diligence by tracking down every lead in an effort to locate and apprehend card. So that does confirm, anderson, some of what we had been reporting on earlier, that in our colleagues working their sources have said that it is not clear at all whether he is there, and she has just confirmed this public officer has just confirmed that it is unknown whether he is there or any other residence connected to him. Its been a very methodical operation here this evening, we can tell you, for last hour and a half or so. Were in the dark. Just to reiterate, we reported this last hour, but were in the dark now because when they poured back in here at roughly 7 00, maybe a little bit before 7 00 eastern time, with all these assets and kind of started to flood the area here, they gave us very strict instructions, turn your lights off because having the lights on is endangering the safety of Law Enforcement. So thats why were in the dark here. And then over the next 30 minutes or so, we witnessed and heard commands and appeals from a Law Enforcement officer on a loudspeaker to whoever might have been inside to come out with their hands up. They understood this could be inti intimidating. They dont want anyone else to get hurt, but they wanted them to come out with their hands up and nothing in their hands and to walk to the front of the truck in the driveway and follow instructions. But then the dialogue simply stopped, anderson, probably 40 minutes or so ago and there has been no dialogue since then. Theyve been methodically moving assets on the ground, in the air around that house. Brian, is it one structure on this property . And does the suspect have access to other properties somewhere . Or family properties, relatives, the like . We can tell you that this is appears from our angle to be one structure on this property. We did see Law Enforcement personnel kind of fanning out to the left of the property when they first kind of poured their assets back in for the second time tonight. To the left of the property seems to be some kind of a farm field. But, you know, again, when we saw those personnel doing that fanning out, that could be standard procedure just to secure the area or move around. We dont know what if any other properties he has access to. We do know that he on the other hand he owns a small powerboat and that the coast guard is joining in the search for any suspicious vessels, because they found his vehicle, of course, weve been reporting that, almost for 24 hours now, they found his vehicle, or a vehicle connected to him at a boat landing dock. So those are the properties that we know he owns. We know he owns a boat, and we know he owns this house. And brian, just in terms of what the image that we are showing on the left, that is the house illuminated. On the right, that is i assume the vehicle Law Enforcement truck has the light thats casting the illumination on the house . Is that correct . Yes. The object illuminated on the left is the house. The object on the right is a Law Enforcement vehicle. It looks like a large tactical armored vehicle. Now the way the spotlight has been shifting around just heard some kind of a thud, but that may not be anything. But the way the spotlight has been shifting around, i cant say for sure whether the spotlight has always been operated from that vehicle. Because the spotlight has really been kind of shifting one way and another and another at very odd angles. So how much flexibility that vehicle would have to do that, i dont know. Josh campbell, just in terms of the larger manhunt, this is said to be the largest manhunt certainly in recent maine history. Talk a little bit about what other what this day has been like, not just the last hour or so that weve been watching this scene. Well, what we are seeing for ourselves and andy mccabe knows this as well working in the fbi, when you these manhunts, you have teams that are constantly moving from location to location based on the flow of information that Law Enforcement is getting. We happen to be seeing this right now for ourselves on our camera. And ill point out, anderson, i know you mentioned at the top that were obviously not describing the individual tactical movements of officers for officer safety purposes. Its important for viewers to also know that state police are also aware of our shot. Obviously this is important to make sure that were not putting them in danger. But what were seeing for ourselves on the screen is something that happens time and again where there are no cameras. And that is you have these teams. They get assigned. Often multiagency efforts that are working together. Obviously we know about the host of resources being barred from all these agencies. And theyll get farmed out tips. Were getting something at this location. Lets go check this out. Someone called in. They saw something here. This is a process that they go through, that theyve been going through since this occurred. Now over 24 hours ago, this Mas
