Washington DC Shooter Identified as Dr Matt Lambert After Gym Gunfire Leaves One Dead and Four Injured

Police say one person was killed and four others were wounded after the gunman left the gym and fired again nearby before dying in his apartment.

  • Matt Lambert, an emergency physician, opened fire at VIDA Fitness on 15th Street NW in Washington on Thursday, killing one person and wounding four others before police identified him as the suspect.
  • Court records reveal Lambert sued the condominium association in 2025, alleging water intrusion and mold problems rendered his penthouse at the Metropole unusable since 2024. Authorities are investigating whether this dispute motivated the attack.
  • After the gym shooting, Lambert barricaded himself in his seventh-floor apartment and spoke with police negotiators for approximately one hour before officers heard a gunshot and found him dead from an apparently self-inflicted wound.
  • Approximately 50 people were exercising at VIDA Fitness when gunfire erupted shortly before 08:00. Officers arrived within approximately 30 seconds, discovering one victim dead at the scene while four others were hospitalized, one in critical condition.
  • Council Member Brooke Pinto told NBC Washington that preliminary information suggested Lambert targeted someone at the fitness centre and was involved in ongoing condominium litigation. Washington authorities continue investigating the motive as the case unfolds.
