What Happened
Deputy Sheriff Tony Hinostroza was killed in a vehicle crash as he responded to assist other deputies who were involved in a vehicle pursuit in Riverbank.
The pursuit started after deputies had been called to check on the welfare of a subject who was sleeping behind the wheel of an SUV. As the deputies contacted the man he accelerated away from them, leading them on a pursuit.
As Deputy Hinostroza responded to assist in the pursuit his vehicle left the roadway and struck a utility pole at the intersection of Claribel Road and Terminal Avenue. Rescue personnel were unable to resuscitate him at the scene.
