One officer killed, another seriously injured after shooting that led to 15-hour standoff with gunman: Cops

Authorities in California have arrested a man accused of shooting two Pomona police officers before holding SWAT team members at bay during a 15-hour standoff.

According to Fox News, one officer was killed and the other wounded when they were shot as they chased the suspect on foot following a vehicle pursuit.

The gunman allegedly led officers to a nearby apartment complex where he was cornered in a unit and began firing his weapon through the door.

After one officer was hit, the second attempted to render aid and was shot in the face by continuing gunfire.

Reports indicate 30-year-old officer Gregory Casillas was killed in the line of duty.

California Gov. Jerry Brown reportedly issued an order to honor Casillas for his “brave sacrifice” by lowering the state’s flags to half mast.

“He left his family at home to protect yours and his ultimate sacrifice will never be forgotten,” said Pomona Police Chief Michael Olivieri.

The officer’s death prompted an outpouring of support from locals and the law enforcement community, which included dozens of police vehicles and numerous officers paying tribute outside of the Los Angeles County Coroner’s Office Saturday morning.

As KABC reported, LAPD Chief Charlie Beck was one of many to honor Casillas’s service.

Following surgery on Saturday, the other officer involved is expected to recover from injuries sustained in the shooting.

After the shooting, tactical officers attempted to resolve the standoff through the use of tools such as cameras and flash grenades.

When the 15-hour ordeal was over, the suspect was reportedly led from the apartment in his underwear.
