Antioch Driver Convicted of DUI Manslaughter and Hit-and-Run in 2024 Bicyclist Death

ANTIOCH — November 7, 2026. A Contra Costa County jury found Alexander Pedro Mayorga, 40, guilty of gross vehicular manslaughter while intoxicated and other counts after the crash that killed bicyclist Linda Alize Wooldridge, 29.

July 2024 collision

Prosecutors said Wooldridge was riding in a marked shared bicycle lane on Lone Tree Way on July 27, 2024, when a vehicle driven by Mayorga struck her from behind. The car continued and crashed into traffic-signal poles farther down the road. She died of injuries sustained in the collision.

What jurors found

The verdict, returned November 4, included gross vehicular manslaughter while intoxicated, DUI causing injury, driving with a blood-alcohol concentration of at least 0.08% causing injury, and hit-and-run involving death. Jurors also upheld special allegations, including a blood-alcohol level of 0.20% or higher. The judge separately found an aggravating circumstance concerning the victim’s vulnerability.

Sentencing still ahead

Mayorga faces up to 15 years in prison, with sentencing scheduled December 12 at 8:30 a.m. at the A.F. Bray Courts Building in Martinez. A conviction has occurred; the final sentence has not yet been imposed. The case was prosecuted by the DA’s specialized impaired-driving unit, which receives grant funding from the state Office of Traffic Safety.
