SAN FRANCISCO—On September 23, 2026, the San Francisco District Attorney’s Office secured a conviction against Daniel Schuhmacher, 37, after a trial by jury for driving under the influence (PC 23152(a)).

According to testimony and evidence presented at trial, On May 8, 2025, at approximately 9 a.m., the San Francisco Police Department received a 911 call reporting a drunk driver on the US-101 southbound, north of Paul Avenue. A few minutes later, a California Highway Patrol officer arrived at the scene where the 911 caller shouted out their window stating that there was a drunk driver behind them.

Upon moving Schuhmacher to a safe location off the highway at Beatty Avenue and Alana Way, CHP officers conducted a driving under the influence (DUI) investigation and arrested him for driving under the influence.

The case against the defendant was successfully prosecuted by Assistant District Attorney Patrick McKuin with assistance from paralegals Raquel Paz, Nohemi Torres, and Adrianna Loomis, District Attorney Investigators Ted Martin, and Perla Ortiz, and IT support from Leland Chan. Prosecutors were able to develop a strong case against Schuhmacher based on the California Highway Patrol’s thorough investigation and assistance.

For the most serious DUI felony cases, the SF District’s Attorney’s Office established a Felony DUI Vertical Prosecution Unit with a grant from the California Office of Traffic Safety, through the National Highway Traffic Safety Administration.
