DC shooting suspect identified, previously sued building's HOA: sources

With the latest on that mass shooting in the Logan Circle neighborhood of northwest D.C. At this hour, police remain on the scene as they piece together what happened. We've got live team coverage off the major developments in a moment. We'll check in with our chief legal correspondent, Katie Barlow, and what we're learning at this hour about that suspect. But we start with our Tom Fitzgerald at Logan Circle with the latest today. Tom. Well, good afternoon to you, Marina. Life is slowly trying to return back to normal here in this Logan Circle neighborhood, but it is going to take some time for that after what people went through and experienced down here today. As we said at the top of this broadcast, we can tell you that the suspect in this shooting, Matt Lambert, is dead. Died of a self-inflicted gunshot wound after opening fire down here in Logan Circle area this morning. Now, this shooting led to a massive law enforcement response with heavy equipment forcing 11 schools to shut down with residents and business forced to shelter in place. Let's show you the scene from earlier this morning. We're told this all happened just after 8 a.m. this morning as people were getting ready to get on with their day. It was the Vedas Fitness Center. About 50 people were inside working out just a few blocks from where we are right now. The four other people who were shot, we were told one person has critical injuries, the other three non-life-threatening injuries. Police say the gunman, Matt Lambert, began shooting from outside the gym, making his way in, and then the suspect made his way out of the gym, barricaded himself inside of a seventh-floor apartment where he was speaking with police negotiators for about an hour. That's when police say the standoff ended when they heard a gunshot. And the suspect, Matt Lambert, killed himself. Earlier today, D.C. Interim Police Chief Jeffrey Carroll said police arrived quickly and found multiple victims in multiple locations. There is one person that was shot and deceased inside a gym. We have some other individuals that were actually across the street working on a construction site. We have the report of another individual who was inside the lobby area or in the alley area. As you can imagine, we're not only investigating, but we're also interviewing those witnesses as they went to different hospitals. So we have officers there. Some are able to be interviewed right away. Some, based on their medical treatment, is going to take more time to interview to get more details on that. I'm going to start getting texts about this situation. And you see it's, you know, you see four people shot and then you see maybe five people shot and then you start to wonder, OK, is it going to be six? Is it going to be 10? Is it going to be 20? Now, D.C. Councilmember Brooke Pinto is telling Fox 5 that the fatal victim in this case, she identifies as the manager of the condo building where Matt Lambert lived. D.C. Mayor Muriel Bowser today commending the quick and overwhelming police response to this today, calling this, quote, that she was devastated by this loss of life. We're live in Northwest today. Marina, we will send it back inside to you. Fitz, thank you for that update, and let's continue our coverage at this hour with what we know about that suspect so far, just after being identified. Fox 5's chief legal correspondent, Katie Barlow, has been digging into Matt Lambert's background. Join us now with what we know at this hour. Katie? Hey guys, just a quick update from the scene here. First of all, we've got several police cars moving by me, but I'll tell you that it looks like a number of individuals have now left the condo building that was near the center of what happened this morning, which is just behind me here on 15th Street. Groups of individuals were being escorted across the parking lot across the street with... luggage and large bags in their hand. I'm not sure if that's people who are exiting the condo building, but that's what it looks like. That's what it appears and perhaps necessary given what's happened to the condo building over the course of the morning. So what we know about the suspect. His name is Dr. Matt Lambert. He has a website, what appears to be him. He is a 20-year board-certified emergency medicine with 20 years of clinical experience, at least according to his website. He appears lately to have set his own consulting business up, but he, in what we believe is his Twitter account, tweeted out this morning, my manifesto is an engineering report, and that appears to refer to a number of engineering and structural and internal issues. Related to this condo, which are also laid out in a lawsuit that was filed in D.C. Superior Court back in March of 2025. In that lawsuit, he details mold, moisture intrusion and some related issues. Now, the most recent filing in that case was actually just a couple of weeks ago on October 26th, where he was actually asking the court for more time in order to meet his deadlines in the case because he said the condo had just dropped another 1,500 pages of... What's called discovery, which is basically information that would be relevant for him to look through related to that lawsuit. He also said that he paid $15,000 over the course of 2023 and 2024 to the condo as part of a special assessment to help address some of those issues. Clearly, he felt like those weren't fully addressed. And we also understand that that suspect is now deceased from a self-inflicted gunshot wound and that he lived in that building in one unit, 704, right behind me. He was also complaining on behalf of several units that appeared to be disturbed, as he claimed, by similar issues throughout the building.
