Man shoots himself after hour-long standoff with police in Thornton, police say

120th Avenue was closed between Holly and Quebec streets as police negotiated with the suspect.

THORNTON, Colo. — There was a large police presence in the area of 120th Avenue and Monaco Street in Thornton Thursday evening as police negotiators talked to a man with a gun, the Thornton Police Department (TPD) said.

TPD said they were called to the 7000 block of 120th Avenue after a family asked for help with a family member who was acting erratically and appeared unstable. Police said in a news release that the male suspect was reportedly driving around a family member's home. 

Police said when they arrived at the house, the man was inside his vehicle. When police tried contacting the man he pulled out a gun and shot at them, according to TPD. Police returned fire at the man, but police said the man was uninjured and no officers were hit. 

Police were on the scene for about an hour and a half. While negotiators were talking to the man, he turned the gun on himself, police said. He was taken to the hospital for treatment. The man was pronounced dead at the hospital, according to the news release.

TPD said an autopsy confirmed the man died from a self-inflicted gunshot wound and that during the autopsy, an additional gunshot wound to his foot was discovered. 

Police said the identity of the man will be released by the Adams County Coroner's Office. 

The investigation will be turned over to the 17th Judicial District Critical Incident Response Team, police said, and the involved officers have been placed on paid administrative leave in accordance with standard protocol.
