- Police found him dead after a stand-off at his flat.

## Summary

A 55-year-old doctor, Matt Lambert, fatally shot building manager James Stuart at a gym in a Washington DC apartment complex and injured four other people. After the shooting, Lambert told another building manager that he had attacked five people because he believed the complex’s owners would not address problems in his flat.

Lambert had been in a long-running dispute with the condominium association over water damage and mould, which he claimed had made his home unliveable and caused about $290,000 in damage. He barricaded himself in his penthouse and reportedly fired at police; after roughly an hour of negotiations, officers found him with a self-inflicted gunshot wound. His online posts and a lawsuit had detailed his complaints about repairs and building conditions.
