SAN DIEGO (CNS) - A 54-year-old man threatening suicide, and mimicking that he had a gun and would shoot intervening officers, was shot and killed by CHP officers on the San Diego-Coronado Bay Bridge.

San Diego Police and the California Highway Patrol received a call about a man standing on the bridge in the westbound traffic lanes at 1:29 a.m. Sunday, SDPD Lt. Ernie Herbert said.

CHP officers arrived on the scene and found a 54-year-old man pacing in the traffic lanes, and threatening to jump from the bridge. The officers attempted to talk to the man but were unable to convince him to seek help.

The man threatened the officers, saying that he had a gun and would shoot if they tried to stop him from jumping, Herbert said.

While officers tried to negotiate with him, the man reached into his pocket and quickly removed it as if he were pulling out a gun. Three CHP officers believed he was producing a weapon and fired defensively, Herbert said.

Paramedics were unable to save the man's life. The man's identity is being withheld until his family can be notified, Herbert said.

The CHP officers involved in Sunday's shooting are assigned to the San Diego office and have been with the CHP for 2-3 years each, Herbert said.
