MARTINEZ (CBS SF) — A 41-year-old Discovery Bay man fatally shot by a sheriff’s deputy after allegedly firing his own gun at the deputy in unincorporated Contra Costa County near Martinez on Wednesday has been identified by the sheriff’s office as Paul Ridgeway.

Shortly after 9:30 a.m. Wednesday, two deputies were finishing up a response to a call on Adelaide Drive when one noticed Ridgeway, who had an outstanding warrant and was on foot near Pacheco Boulevard and Adelaide Drive in the Vine Hill community, according to the sheriff’s office.

The deputy went to contact him, but Ridgeway allegedly reached into his waistband while running away, prompting a foot pursuit. The deputy commanded him to show his hands and tried to physically control him, sheriff’s officials said.

During the struggle, Ridgeway allegedly pulled out a firearm from his waistband and fired a shot toward the deputy’s head but missed. The deputy returned fire and shot Ridgeway, who was pronounced dead at the scene, according to the sheriff’s office.

The Deputy Sheriff involved in this incident is Matthew Gauthier. He has been with the Contra Costa Sheriff’s Office for over eight years. Per protocol, Gauthier has been placed on paid administrative leave pending the investigation into the shooting.

Ridgeway had a no-bail warrant for evading and resisting arrest in another county, was an alleged gang member with multiple prior law enforcement contacts for assault, theft and other offenses, sheriff’s officials said.

Authorities also confirmed that Ridgeway was validated as a member of the Family Affiliated Irish Mafia (FAIM) and an associate of the Nazi Low Riders, both of which are white supremacist prison and street gangs.

The autopsy took place Thursday morning and confirmed his death was caused by the gunshot wounds he received. Toxicology tests will also be conducted.

The case remains under investigation by the county sheriff’s and district attorney’s offices. Anyone with information is asked to contact the sheriff’s office at (925) 313-2600. Any tips can be sent to or by calling (866) 846-3592.
