A doctor has been named as the gunman who shot one person dead and injured five others near the White House before turning the gun on himself during a standoff with police. Matt Lambert, 55, carried out the attack outside a gym in Washington, DC, at around 8am local time.
Lambert, described as a disgruntled doctor, was reportedly involved in a dispute with his homeowners' association over black mold in his $1.1 million penthouse. After the shooting, he barricaded himself inside his apartment and fired through his door at officers before shooting himself. He later died from his injuries.
Police statement on the incident
Jefferey Carroll, the interim chief of the Metropolitan Police Department, said: "We believe there was some sort of a conflict with the apartment building, but we don't have much more than that."
An X account, named OfMiceandMold, which appears to belong to Lambert, has been discovered. It contains several posts about a rodent infestation and leaks in his apartment.
Final post before the attack
The account's final post, made just before the shooting, stated: "My manifesto is an engineering report."
