Washington, DC Gunman Kills Manager, Wounds Four

A 55-year-old doctor, Matt Wade Lambert, killed the manager of his Washington, D.C., apartment building and wounded four people in a shooting near Logan Circle before dying by suicide. Police said Lambert barricaded himself in his seventh-floor condo and fired at people from its balcony; officers also reported a fire after he damaged a gas line. Investigators believe the attack was connected to a long-running dispute over mold, moisture and maintenance problems, which Lambert had pursued in a civil case against the building’s management and homeowners association. One wounded person was in critical condition, while the others were not reported to have life-threatening injuries.
