Condo manager says shooter confessed over phone, citing dispute over apartment conditions
Police say 55-year-old doctor Matt Lambert killed one person and injured at least five before dying by suicide, after allegedly confessing to the attacks during a phone call with a building manager.
Police identified the gunman as 55-year-old Dr. Matt Lambert, a resident of a condominium in Washington DC’s Logan Circle neighborhood. On Thursday morning, Lambert shot condominium manager James Stuart inside the building’s gym, then fired from his balcony at four additional people, one of whom remained in critical condition. He later barricaded himself in his unit and was found dead from a self-inflicted gunshot wound. Authorities later confirmed a sixth victim, a woman with a non-life-threatening graze wound.
Building manager Charelle Ferguson said she spoke with Lambert by phone around 9 a.m., about an hour after the shooting began. She told the Washington Post that Lambert expressed frustration over mold and water damage in his apartment and said, “The only way people will pay attention, you have to do something.” Ferguson added that Lambert confessed to shooting the five people during the call.
Court records show Lambert had sued his condo association in 2025, alleging the association failed to address water damage, mold and moisture problems that began after exterior work on the building. The association denied negligence, and the civil case was still pending at the time of the shooting.
Lambert’s civil-case attorney, Joel Braithwaite, said he last spoke with his client on Tuesday and that Lambert had seemed fine. Braithwaite expressed surprise at the incident, noting that Lambert worked in the medical field.
