The horrifying shooting in Washington, D.C. has left everyone shocked. The shooter reportedly opened fire, killing one and injuring four people. He took his own life after killing the victim. Now the cops have identified both the shooter and the victim and reported that it was a targeted attack.

Shooter and the victim identified in D.C. shooting

Metropolitan Police interim Chief Jeff Carroll identified the deceased victim in the November 12, 2026, shooting as 46-year-old James Stuart. According to NBC News, he was pronounced dead at the scene after two males and two females were transported to the hospital from the scene. Police have reportedly also identified the suspected shooter as 55-year-old Matt Wade Lambert.

According to MedPageToday, Matt Wade Lambert was a doctor. A profile reportedly about him described him as a clinician and entrepreneur. DocInfo.org says that Matt holds active medical licenses in West Virginia and Montana. Neither license lists any disciplinary action. Jeff Caroll further shared that the officers located the suspect inside an apartment, which officials said he lived in, with a self-inflicted gunshot wound.

As per the report by NBC, the four victims wounded in the shooting were shot by the suspect firing from his patio balcony area. After opening fire inside the gym, Matt Lambert entered back into the building and went up to his apartment on the seventh floor. Jeff Caroll reflected on what possibly happened and said:

"He had a patio balcony there, and we believe he shot from that location, striking the four other individuals who were shot in this case. We do know that there has been an ongoing dispute between the suspect in this case and the building, condo, homeowners association management regarding maintenance issues, mold, and the like. That there was a civil case that he filed against them. So we believe that it’s related to that."

Why did Dr. Matt Lambert allegedly shoot the victim?

According to reports, Matt Lambert was involved in an active dispute with the victim, James Stuart. The alleged shooter's lawyer, Joel Braithewaite, who was representing Matt in a civil case against his condo, said the legal dispute and home maintenance cost the suspect USD 300,000. The lawyer said his client had lived in the condo since 2017, and records showed Matt purchased the unit for more than USD 1 million in 2016.

Joel Braithewaite said his client considered the D.C. condo "his prized possession." However, soon after moving in, he reported mold and water issues and spent thousands on mold mitigation. According to the lawyer:

"He moved back to the mountains of West Virginia, where he has a country home, and he’s out there because that’s where he grew up. Once this situation became untenable, he moved out and cleared it out."

Joel also said the litigation against housing management became extremely expensive, and that last week Matt Lambert reported he had paid over USD 300,000 out of his own pocket "because the case was not going to wrap up in a day or two." He added that his client felt wronged and thought his condo association took no ownership of the issues he had with the unit. Speaking on the unit, Braithewaite said:

"It doesn't look hospitable, and no one would want to live in those sorts of situations when you paid for something substantially different."

Meanwhile, an X (formerly Twitter) account has also been linked to Dr. Matt Lambert. According to reports, authorities have suspected that the shooter shared his frustrations with maintenance issues at the apartment building on the said account. The poster, who used the handle "ofmiceandmold", shared dozens of pictures and complaints about the penthouse condo and building allegedly having mold issues, rodent and insect problems, and water damage.

The posts date back to October 2025. However, the ownership has not been confirmed so far. In one post from December 2025, the account shared an image allegedly showing a cockroach in the hallway. Other images showed supposed notices alerting residents that the gym dryers weren't working and that the trash compactor was having issues. The account shared its last post around the time of the shooting.
