A 20-year-old Santa Rosa woman will spend 90 days in jail and on work release after pleading no contest in the hit-and-run death of a pedestrian last summer.

Alejandra Vasquez was sentenced last week in Sonoma County Superior Court for the Aug. 1, 2024, death of 33-year-old Mahlon Weaver. Judge Mark Urioste ordered her to begin a 30-day jail term Aug. 13, followed by work release. She’ll remain on probation through June 2027.

Vasquez has been out of custody since shortly after the crash. In a presentence report, probation officials described her as remorseful and said her actions were the result of “panic and poor decisions under duress.”

“Though deeply misguided, her behavior appears driven by fear and immaturity rather than malice or intentional harm,” the report said.

The crash occurred around 9:40 p.m. along Hearn Avenue near the Sonoma-Marin Area Rail Transit tracks in Santa Rosa. Home surveillance video captured the moment Weaver was struck.

Police said the driver — later identified as Vasquez — stopped for about 90 seconds before fleeing.

According to the report, she had turned on her hazard lights and asked Weaver if he was OK. Then, in a panic, she drove away without calling 911. Instead, she phoned her parents.

Her father, Rafael Vasquez, told her to come home and later hid the white Lexus IS 250 in their garage before returning to the crash site, the report said.

“We were just all panicking. We didn’t know what to do,” Alejandra Vasquez told probation officials. “When (police) came later that night, I told them everything that happened.”

Investigators tracked her car using footage from a traffic camera that recorded the license plate. She was found on Blue Sky Lane, about a mile from where Weaver died.

Rafael Vasquez was also described as remorseful in the report. He was arrested on suspicion of helping conceal the car and later charged with a misdemeanor count of being an accessory. He’s scheduled to appear in court July 30 for a hearing on potential diversion — a program that can postpone and ultimately dismiss charges if certain conditions are met.
