Man Arrested in Fatal Police Shooting After 15-Hour Standoff


One police officer in Pomona, Calif., was shot and killed on Friday night and another was seriously injured by a gunman who barricaded himself inside an apartment for 15 hours before being taken into custody on Saturday, the Los Angeles County Sheriff’s Department said.

The officer who was killed was identified as Greggory Casillas, 30, by the Los Angeles County Department of Medical Examiner-Coroner. Chief Michael Olivieri of the Pomona Police Department said that Officer Casillas joined the department in September and was about to complete field training.

Officer Casillas, who is survived by his wife and two children, was “a hero, a man to be looked up to,” Chief Olivieri said during a news conference after the arrest. “He left his family at home to protect yours, and his ultimate sacrifice will never be forgotten.”
Late Saturday, the sheriff’s department identified the man they had arrested as Isaias De Jesus Valencia, 39, of Pomona. In a brief statement, the authorities said he would be charged with murder and attempted murder and was being held without bail.
They tried to stop the driver, who led them on a pursuit before crashing into a parked vehicle.

“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. “The officers attempted to contact the suspect when the suspect began to shoot through the door, striking two officers.”

After Officer Casillas was shot, a second Pomona officer tried to pull him to safety but was shot in the face, Sheriff Jim McDonnell of Los Angeles County said during a news conference. Other officers extracted the officers who had been shot.

They were taken to Pomona Valley Hospital Medical Center, where Officer Casillas died. The other officer, who was in serious condition, was undergoing surgery and expected to survive.
