captivity, they used to sing my songs to ease the pain. and what a joy for all of us to see those girls home with their parents. thanks for joining us. thanks for joining us. "ac 360" starts now. -- captions by vitac -- www.vitac.com tonight on "360," we are about to hear from authorities, after a gunman, who's now dead, opened fire on the campus of the university of nevada in las vegas, killing three. -- claiming with the facts. and a cnn investigation into the cover-up of sexual misconduct in the coast guard, the action it prompted from the coast guard today. we begin with breaking news in las vegas, the press conference by authorities is starting. let's listen. >> first, i would like to reiterate to all of you that there is no more ongoing threat to our community here in las vegas. i'd also like to tell you that we do know the identity of the suspect in this case, but i will not be releasing his name tonight until after the next of kin notification. as y'all know, of course, this is a tragic day for all of us in southern nevada. and at approximately 11:45 a.m., lvpd dispatched received reports of an active shooter at the unlv campus. campus police responded to the scene and engaged the suspect immediately right outside beam hall. lvpd officers also responded simultaneously. i can tell you today, three of the victims are confirmed deceased. there is a fourth victim, who suffered a gunshot wound, and is now currently in sunrise hospital, upgraded to stable condition. in addition to that, there were four additional people who were transported from the scene to nearby hospitals, suffering from panic attacks. two of our officers were treated at umc for minor injuries, which were received, while searching the vast rooms and buildings for victims at unlv. our hearts go out to the entire unlv community. no student should have to fear pursuing their dreams on a college campus. what happened today is a heinous, unforgivable crime. i want y'all to know something. it's a crime that we train for each and every day. when there is an active shooter threat, the men and women of the southern nevada first responder community, police, fire, and ems, come together to respond quickly and decisively with zero hesitation. within minutes, both on and off-duty responders raced to the campus to prevent further loss of life. on a personal note, i'll tell you that after 1 october and all the time and effort and energy that we put together in training with the men and women of law enforcement, the fire service, and ems, watching how seamlessly they worked together today made me very, very proud to be their sheriff. importantly, there was a gathering just outside of the building where the students were playing games and eating food. there were tables set up for them to build legos. and if it hadn't been for the heroic actions of one of those police officers who responded, there could have been countless additional lives taken. armed confrontation of the suspect by law enforcement stopped the suspect's further actions. i'm proud of the courage of these officers and the unlv campus police and how they demonstrated that today. and with that, i'm going to introduce the governor of the great state of nevada, joe lombardo. governor? >> kevin, thank you. thank you for your opportunity to speak tonight. i think it's important for people to realize the partnership that is formed as a result of my career at lvpd and with kevin, the sheriff, himself, and the confidence that i was assured of when i got notified today. i had no doubt that the response would be appropriate. it would be swift. it would be quick, to the satisfaction of all the nay sayers that we normally experience during critical incidents. and today lvnpd did a fantastic job along with the university pd did a fantastic job. and after the action is settled here and our concern for the victims are bolstered and satisfied, i will be absolutely proud of the response of the first responders. i'll be absolutely proud of the community of unlv. and i'll be absolutely proud of the community of las vegas and the state of nevada. i had some formal comments to be said, but the important piece is i'm here to show the solidarity between the community and the law enforcement community and ensure, on behalf of the state of nevada, we are here to help provide resources to the benefit of the victims and to express my concern for the victims and favorable thoughts to the families. and to ensure that we move forward as a society and as a community. and to assure the community we are doing everything within our ability to address these situations appropriately and with the knowledge that we receive on a continual basis. so, kevin, thank you. i appreciate that. and i think it's appropriate that chief of upd comes up and says a few words and the positive response of his police department. so, chief alex garcia, please. >> thank you. good evening. my name is adam garcia. i am the university police chief. first of all, let me begin by telling you all how heart broken we are on our campus for what happened today. on behalf of the chancellor, the board of regents, and president whitfield, i am passing along our profound sense of loss for what occurred and the loss of life took place. as the sheriff said, our officers collectively, upd as well as metro, responded to call for shots fired approximately 11:45. two of our detectives responded to the scene. it immediately engaged the suspect in a shootout. the suspect was struck and is deceased at this time. the campus was almost immediately closed, and out of an abundance of caution, all nevada system prior education institutions in southern nevada were as well closed. unlv will remain closed for the remainder of today, tomorrow, and friday. and additional determinations will be made as to whether or not the school, the university, will reopen next week, which will be finals week. so, with that, i will turn it over to commissioner gibson. >> thank you, chief. i'm jim gibson, the chairman of the clark county commission. and i'm here to express the shock that we all felt, as a community. but at the same time, the enormous relief that we feel as a result of the great work of the first responders. we want everyone to know that anyone who has been affected will have the resources available to them to ensure that they have an opportunity and a way, a pathway, to work through whatever the effects have been. my colleagues on the county commission -- >> you're listening to law enforcement talking about the shooting at unlv. four people shot, three of them dead, plus the gunman also, who is not named. the latest from authorities and nevada's governor in las vegas las vegas. joining us now is cnn chief law enforcement analyst john miller, also charles ramsey, former d.c. police chief. clearly the response time was immediate, they say, and it was two detectives from the campus that engaged and killed the gunman. >> right. what we learned from chief adam garcia a minute ago is it's two of his detectives from university of las vegas pd were first there. and he said they engaged in a shootout, which suggests the suspect shot back. so, they had a gun battle and were able to neutralize him. >> what do we know about the gunman? >> well, we're learning more. as you noted from the press conference, they didn't name him. we're not going to name him either. but he is not what i expected. he is a 67-year-old college professor, kroer professor, who studied business processes, organizational structures, and taught in two colleges in georgia and north carolina. what we don't know is, what was the motive? what was his connection to the university of las vegas? did he apply for a job there? had he taught a class? all that's unknown. las vegas metro pd and unlv police being assisted by other agencies, including the fbi. they're going to do a search of his residence, which i believe is in henderson, nevada, not far away. no apparent police record. so, the picture is just emerging of the suspect. the gap for us right now is, what was his connection to the school? or were the victims intended because of some personal reason? >> stephanie elam, you've been following. what stood out to you? >> striking to hear that it was the campus police officers that engaged in the shooting and brought down the shooter in this battle. also there was something in there from the sheriff. we're going to have to learn more about it. but apparently there was something going on with the students outside of beam hall, and that's where the shooting sounds like it took place, this first shootout. and those students, whatever the officers did, they intercepted, interceded. they moved these kids to safety, it sounds like, during this time when, you know, they should be studying there because they're getting ready for finals before going on to winter break. that was also noteworthy. he also said there are four more people who are hospitalized for panic attacks. and the one person who was in critical condition, we knew earlier, that is in sunrise hospital has been upgraded to stable condition. so, that's also some good news on that front as well because we didn't have any idea of that change there. but still, what we know is that this all transpired very fast. you heard them say they got the first call at 11:45. i can tell you very shortly thereafter, i was on tv talking about this. and by 12:30 local time, they were already saying the situation was neutralized. this person did not kill themselves. he was taken down by the police officers. so, these are all little bits of information. but this happened very fast. i was in las vegas to cover that october 1 shooting. these people are trained to do this. and you heard the sheriff say that people who are on duty, off duty, all of these first responders coming together to respond. this is a city that's prepared for it. and they took that seriously today. >> chief ramsey, obviously we know from all the past incidents how critical the initial response is, a timely response. as he was saying, as the sheriff was saying, on duty, off duty law enforcement. as soon as the call came out, 11:45, they responded to the campus, but it was these campus detectives two, of them, who engaged with and killed the gunman. obviously he'd been able to kill three people and shoot another person, but that fast response was critical. >> it's very critical. and, you know, we don't often talk about university police departments and their capabilities. but university police departments are very well trained, and they're fully aware of the fact that should there be a shooting on their campus, they are more than likely going to be the very first to arrive on the scene. and that's what you saw today. and they took action, did a tremendous job, not only the university police but obviously the metro police. and they were able to minimize the amount of damage this individual was able to do because they did respond so quickly. they were able to kill him and stop the threat. and they did an excellent job. >> john, at this point, does law enforcement spend a lot of time looking at what motive is? does it matter at this point? >> obviously there's no criminal case. they don't need to know it. but it's important to understand what the drivers behind these threats are. that's why they'll go through the search warrants. that's why they'll try to peel back the layers. >> the fbi studies pretty much every -- they put out extensive reports on every active shooter. >> they do, and they collect the statistics. there's a reason for it beyond just the academic study, is what they're looking for is common traits, common signals, like leakage, where 85% of them say things before they do it that, you know, they're hoping they can train people to recognize and maybe report. because there are these cases we hear about occasionally where someone was planning it, plotting it, and they were stopped because people picked up on these things. it's just interesting that we're in las vegas. the governor, who spoke to us in this press conference, joe lombardo, who was the sheriff during the las vegas sniper attack and has since gone on to be governor. kevin mcmay hill has really built an active shooter response there, which is part of the speed of what you saw and the professionalism of that response. unlv is probably like every college campus in the country now, where they train not only their cops to respond to these things but also their students and faculty. >> john miller, stephanie elam. joining us now is brett forest. he was on the campus. he had to take shelter on the campus when the shooting began. brett, can you tell us what you saw, what you experienced? >> yeah, anderson, i was here for a different assignment this morning. and right when i was wrapping up by interviews with these senior students about to graduate in two weeks, people started coming into our room, barrelling through the doors, saying, there's a shooter, active shooter. moments later, the text message alert system from unlv began sending the notice that there were gunshots on campus. minutes later, a second notice saying, active shooter confirmed. so, i was with dozens of students here, i'd say about 50 people, students and then also some faculty and staff. and we immediately had to shut the doors, go as deep into this building as we could. and these students were in the middle of giving their senior presentations. so, we had to drop everything, go back to this back room, and shelter in place. e we were there for four hours. this began 11:45 our time and about 3:45 is when police came to our building. they were evacuating them one by one, making sure they were clear of any victims. it took about four hours to get to where we were on campus. and they took all the students over to the basketball center. some of them, i believe, are being bussed to the las vegas convention center for reunification point. but it was scary in those first moments. but these students i was with, amazingly, remain calm. it might be a generational thing, but they kept calm. many were checking in on friends and family around campus, making sure they were safe. but it was tense there for a bit. and yeah, as i said, we were in there for about four hours. >> did you have, at the time, much information about where the shooter was located? i mean, a tsi assume you didn't did you hear any shots? i assume you didn't in the location. >> i did not. and this campus tech system immediately identified the hall, the beam hall. you can see the student union building behind me. and just on the other side of that is beam hall. those were the two buildings that were involved in the shooting. i was, i would say, about a half mile away from there. i didn't hear anything but this campus message system immediately identified the hall. metro police were pushing out information very quickly, which often you don't see every day. but they were trying to keep the public as informed as possible. they were saying what buildings it was in. sunts were well aware of where on campus it was. so, where i was, at least instantly knew they weren't right next to the gunfire. and perhaps that is what helped keep them call. >> brett forest, thank you so much. i appreciate your time. coming up next, new claims of presidential wrong doing by house republicans. but the same question comes with them, where is the evidence? cnn investigates. and later a live report on israel's war on hamas and attempt to corner and kill hamas' leader in gaza. republicans sharing the house yjudiciary and oversight committees will hold contempt proceedings in hunter biden does not appear next week. house speaker mike johnson moves to formalize the impeachment inquiry into president biden with a vote next week, and oversight chairman -- continues trying to connect the president to his yet unfounded allegations of financial impropriety. the president was asked about it this afternoon. >> can you explain to the americans -- to americans why you interacted with so many of your son and brother's foreign business associates? >> i'm not going to comment. i did not. it's just a bunch of lies. >> you didn't interact with their business associates? >> i did not. they're lies. >> his denial -- the question tonight over the days ahead is what kind of evidence do they have to back any of it up. more on that now from cnn's melanie zanona. >> you're seeing a very deliberate investigation following -- uncovering and following the facts. following the truth where it leads. that's what the constitution requires the house to do. and the republicans have done that very methodically. >> reporter: that's house speaker mike johnson moving to formalize the impeachment inquiry into president biden as soon as next week and hoping to appease the far right members in his party. >> i've been pushing for impeachment since the first day he was in office. >> reporter: republicans have leaned heavily on bank records, trying to establish a connection between biden and his son's foreign business deals, a charge the white house has strongly denied. the oversight committee unveiled a new document -- hunter biden's business entity to his father. >> the president's loans to family members raise serious red flags and should have resulted in reported interest income. >> reporter: what the committee didn't say was that the payment wasn't from some foreign entity but instead was hunter biden repaying his father for a car. biden was not in office at the time. republicans have also accused the doj of mishandling the criminal probe into the president's son, claims bought forward by a pair of irs whistleblowers this week. >> they testified how investigators were prevented from following evidence that could have led to joe biden. justice department officials didn't want to talk about dad or the big guy. why is that? because the evidence leads to joe biden. >> reporter: but cnn reporting shows that doj and irs officials, who have also sat for interviews in recent months, have undercut those claims. >> the white house has provided over 35,000 pages of financial documents, over 2,000 pages of treasury reports, 36 hours of testimony. and republicans still cannot point to a single policy decision or action that joe biden has taken that has violated any law. >> reporter: house judiciary chairman jim jordan still believes the most compelling evidence stems from a debunked claim, that as vice president biden pressured to fire -- >> this story is as old as time. you have a politician who does certain things. those actions benefit his family financially, and then there's an effort to sweep it all under the rug. and we know this has happened. the best example is to use the ukrainian energy company, burisma. >> reporter: yet every aspect has been proven false. biden did push for the prosecutor to be fired, but it was consistent with bipartisan policy. states wanted the prosecutor fired because he was soft on corruption. >> it's bizarre. there's no evidence whatsoever that they've -- i mean, it's a clown show over there in the oversight committee. >> reporter: to wrap up their impeachment probe, republicans want to interview over a dozen more witnesses. but their final push is proving to be a challenge. hunter biden has only agreed to testify in public. now, jordan and james comer are threatening to hold him in contempt of congress if hunter does not appear for a closed door deposition next week. >> they're going to stop providing information, then we need to do it. that's where we're at. >> reporter: republicans are hoping to strengthen their subpoenas to hunter biden and others by taking an official vote to authorize their impeachment inquiry. but republican leaders are still working to build support for that vote. and one republican congressman, ken buck, tells me he will vote ag
