D.C. gunman appeared to vent about problems with luxury condo

An X account associated with D.C. shooting suspect Matt Lambert was filled with complaints about mold, rodents and disrepair in his unit in the condo building. The gunman who opened fire at a gym in a luxury condo building in Washington, D.C., Thursday morning had been complaining about mold and water problems in his apartment before the deadly attack that targeted the building's manager, police said. One person was killed and four others wounded in the shooting in the Logan Circle neighborhood. Police identified the victim who was killed as 46-year-old James Stuart, who managed the building. Police said the gunman, identified as Dr. Matt Lambert, 55, shot and killed himself in his apartment after a standoff.

Three firearms were recovered from his apartment, according to law enforcement sources in Washington. An account on X under the name @OfMiceandMold has served as a repository for complaints about the alleged disrepair of the apartment where Lambert lived. In dozens of X posts, he vented his frustration with the Metropole Condominiums' building contractors, EJF Real Estate Services, and his allegations they failed to address problems with his unit. CBS News has reached out to EJF Real Estate Services for comment. Lambert, who ran a D.C.-based healthcare consultancy, had purchased the condo in September 2016 for $1,095,000, according to D.C. tax records. Court
