Colorado gunman killed himself

Matthew Murray, the man who police say shot and killed four people at two separate locations in Colorado on Sunday, died from a self-inflicted gunshot wound, the coroner's office said Tuesday.

A former roommate took this photo of Matthew Murray performing in a 2002 Christmas program.

"The death of Matthew Murray has been ruled a suicide," the El Paso County Coroner's Office said in a statement.

"It should be noted that he was struck multiple times by the security officer, which put him down. He then fired a single round killing himself," the statement said.

Police Sgt. Skip Arms told The Associated Press that Murray shot himself in the head.

Police say before Murray, 24, went down, he shot and killed sisters Stephanie and Rachael Works, ages 18 and 16, and wounded their father, who was in or near their car in the parking lot of New Life Church in Colorado Springs,
