A man accused of shooting and killing a retired Bakersfield police officer outside of Wild Horse Pass Casino has been arrested, the Federal Bureau of Investigation said. 

Officials said John Campos, Sr., 47, was arrested in Phoenix on Friday night around 4:30pm. Police said a call came in about a suspicious person which led them to Campos. Campos tried to flee the area on a bike, but was struck by a vehicle. Police said Campos was not seriously injured, but was taken to a local hospital before being booked into jail.

Officials have been looking for Campos for more than a week. Police say Campos and Pascua got into an argument in the parking lot of the casino and then Pascua was shot. Campos allegedly carjacked another car before fleeing the area.

Campos was booked into the 4th Avenue Jail on Saturday after being checked out at a hospital. 

In a phone interview with 23ABC’s sister station, KNXV, Pascua’s sister said the family has been waiting for the arrest all week. 

“I’m relieved but it doesn’t really make us feel better because we’re all in such great pain, you know? And our lives just won’t be the same without my brother and the family is still shocked over this because it’s a senseless act of violence,” said Angie Tart, Pascua’s sister.

A GoFundMe page set up by Pascua’s family and friends has raised nearly $7,400. 

Campos is scheduled to face a judge in federal court on Monday.
