PITTSBURGH — Pittsburgh police fatally shot an armed man today after they cornered him in his apartment bathroom, ending a more than nine-hour standoff that began as a domestic dispute call.

As a SWAT team surrounded the building, officers shot the man when he made aggressive movements toward them shortly after noon today, police spokeswoman Diane Richard said.

Police had responded to the dispute call after 3 a.m. They tried to negotiate with the man, but he did not come out even after police fired several tear gas rounds into the building.

A man who claimed to be the suspect's brother said he spoke to the armed man by phone and tried to persuade him to surrender. The man told reporters his brother was distraught over a recent death or deaths in his family.

The apartment building was evacuated and residents were loaded onto transit buses to keep warm. Investigators did not immediately allow the residents to return.
