A shooting incident in northwest Washington DC has left one person dead and at least five others injured, as investigators revealed new details about the attack and the suspect’s possible motive.
The shooting took place Thursday morning inside a condominium building in the Logan Circle neighborhood, located not far from the White House. Police identified the gunman as 55-year-old Dr. Matt Lambert, a resident of the building who was reportedly involved in an ongoing legal dispute with the condominium management.
The victim who was killed has been identified as 46-year-old James Stuart, a manager at the condominium complex. According to police, Lambert entered the building’s gym shortly before 8 a.m. and fatally shot Stuart before returning to his apartment.
Authorities said Lambert then fired shots from his balcony at people outside the building, injuring several individuals. Four victims were taken to the hospital, with one reportedly in critical condition. Police later discovered Lambert barricaded inside his apartment, where he was found dead from an apparent self-inflicted gunshot wound.
On Friday, DC authorities confirmed an additional victim — a woman who suffered a non-life-threatening gunshot graze wound — bringing the total number of victims to six.
A building manager, Charelle Ferguson, said she spoke with Lambert by phone shortly after the shooting began. Ferguson told investigators that she had been contacting residents to check on their safety when Lambert answered her call.
During the conversation, Lambert reportedly expressed anger over living conditions in his apartment, including alleged mold and water damage. Ferguson said he told her that drastic action was the only way to make people pay attention before confessing to the shootings.
Ferguson said she was shocked by his actions, adding that Lambert had previously raised concerns about problems in his apartment and that she had been sympathetic toward his complaints.
Court records show that Lambert had filed a lawsuit against his condominium association in 2025, accusing the management of failing to address water damage, mold, and moisture issues that he claimed began after exterior repair work on the building. The condominium association denied the allegations and rejected claims of negligence.
Lambert’s attorney in the civil case, Joel Braithwaite, said he was deeply shocked by the violence. He stated that he had spoken with Lambert just days earlier and that his client appeared normal during their conversation.
“The person I knew as a client is someone who is in the business of healing people,” Braithwaite said, expressing disbelief over the incident.
Following the tragedy, residents of the Logan Circle community gathered Thursday evening for a candlelight vigil to remember the victims and show support for those affected by the violence.
Police continue to investigate the circumstances surrounding the attack, including the suspect’s motive and the events that led to the deadly shooting.
