How did a fight over mold end in a shooting near the White House?

A gunman opened fire inside a Washington gym, about a mile from the White House, shortly before eight that morning.

Witness James Spellman saw it. Within seconds there was a man who fell to the ground, and a pool of blood came out.

The man killed was James Stuart, a 46-year-old building manager. Court records show Lambert had sued that management over mold and damp. Police first counted 4 wounded, one critically, and say they know of no relationship between Lambert and those he wounded.

Police recovered 3 firearms from his apartment, none registered in Washington, and say he used all three. He fired from his balcony, then barricaded himself and died of a self-inflicted wound. On Friday, police added one more victim, a woman with a nonfatal injury.
