An off-duty Monterey Park Police officer was shot and killed outside a Downey L.A. Fitness center Monday.

A call of shots fired was received by Downey PD around 3:30 p.m., and when first responders arrived, they found the shot officer, and attempted CPR before pronouncing him dead on scene.

While the identity of the officer has not been revealed by investigators, Monterey Park Police Chief Kelly Gordon said the officer was new to the force of 76 officers, just two weeks removed from academy training.

This is a tragedy for his family, but this is a tragedy for the Monterey Park Police Department as well, Gordon said in a press conference Monday. It's a tremendous loss. In the Monterey Park Police Department, we're a family and that's the bottom line.

Downey PD closed off the L.A. Fitness parking lot where the incident occurred and as of this writing, have not released many details about the possible suspect, or suspects involved.

My thoughts are with the family of the off-duty Monterey Park Police Department officer tragically killed in today's shooting, Supervisor Hilda Solis said through Twitter Monday. May his soul Rest In Peace.

A procession for the officer was held Monday night.
