A man accused of fatally shooting one California police officer and injuring another was arrested Saturday after a 15-hour standoff, authorities said.
During the standoff, the apartment building had been evacuated as a SWAT team maintained a watch all night and all morning long.
"The suspect fled to a nearby apartment complex where he barricaded himself to a bedroom in one of the apartments", a news release from the sheriff's department said.
Casillas and a second officer pursued the suspect in a vehicle after he allegedly crashed his auto into an apartment complex in Pomona Friday night, The Los Angeles Times and other media reported.
The other wounded officer was shot in the jaw and is in stable condition after undergoing surgery, a law enforcement source told CBS Los Angeles.
Casillas leaves behind a wife and two children, Olivieri said.
Reports indicate 30-year-old officer Gregory Casillas was killed in the line of duty.
The shooting happened about 9 p.m. Friday in the 1400 block of Palomares Street, near Fernleaf Avenue, where officers responded to a report of a barricaded suspect at an apartment complex.
Police received a call about a reckless driver, and when the suspect refused to stop, he led police on a chase that ended when he crashed into a parked vehicle.
So far this year, 17 law enforcement officers across the USA have died in shootings, including an officer killed Tuesday in Missouri.
"He left his family at home to protect yours and his ultimate sacrifice will never be forgotten", said Pomona Police Chief Michael Olivieri. Officials didn't identify that officer, but Sheriff Jim McDonnell said he was shot in the face when he attempted to aid Casillas.
"Anne and I are saddened by the tragic death of Officer Casillas early this morning". One of the residents at the scene said he knows the gunman and described him as a father of three who is battling depression.
Fellow officers saluted his dedication to the force as his body was transported to the medical examiner. "His courageous sacrifice will never be forgotten".
