Authorities say four people are dead after a six-hour standoff with police at a townhome in Aurora, Colo.

Aurora Police Sgt. Cassidee Carlson says a suspected gunman was shot and killed when he exchanged fire with officers after hours of negotiations. Three victims -- all adults -- appeared to have been killed before police were called.

A woman inside the home was able to escape by jumping out a second-story window and alert authorities that the armed man had fired shots inside the home. Before escaping, she said she saw three "lifeless" bodies. She was not injured, police said.

The names and ages of the victims and of the suspect were not released. The Denver Post reported that the victims may all be related.

"We have an idea of who they are, but we obviously want to confirm their identities with the coroner," said Carlson, who declined to release the relationship between the victims and the shooter.
