A Marin County judge on Monday denied a 17-year-old driver's request for a mental health diversion program, meaning she will face prosecution for misdemeanor vehicular manslaughter in juvenile court. The driver, Elsa Laremont Stranczek, is accused of causing a crash that killed four of her friends in April 2025.
During a court hearing, relatives of the four girls who died confronted Stranczek. Christie Batanides, mother of 15-year-old Josalyn Osborn, recounted arriving at the scene to find the car engulfed in flames with her daughter trapped inside. She told the court that Stranczek's initial words upon seeing her were, "My mom's going to kill me… I wrecked the car." Batanides stated, "You had no concern for your friends."
The deadly journey began when Stranczek and her friends were traveling to a sleepover in Woodacre. Minutes before reaching their destination, the driver lost control on a curve on San Geronimo Valley Road, colliding with a redwood tree. The impact caused the car to catch fire.
Ada Kepley, Olive Koren, Sienna Katz, and Josalyn Osborn were killed in the crash. Marley Barclay was the sole survivor.
California Highway Patrol investigators attributed the crash to excessive speed, estimating the vehicle was traveling between 60 and 65 mph in a 40 mph zone. Information from the vehicle's black box was destroyed in the fire, but investigators relied partly on the melted speedometer, which indicated a speed around 60 mph.
Stranczek, who sustained severe burns and reportedly has no memory of the accident, addressed the courtroom for the first time. She acknowledged her role behind the wheel and expressed that she has mourned her friends daily. "Regardless of the outcome, I'll spend the rest of my life trying to honor my friends and their memory," she stated.
Defense attorneys argued for the diversion program, citing Stranczek's cooperation with probation, her 3.73 GPA, and her internship with the Youth Transforming Justice Institute. They highlighted that the probation department had recommended diversion.
However, Marin County Superior Court Judge James T. Chou denied the diversion, stating it was one of the most difficult cases he had encountered in his 37 years of practice, calling it "a tragedy beyond tragedies." He said the decision was made after weighing the teen's circumstances against the need for accountability.
The judge's decision did not fully satisfy all parties. Peg Minicozzi, Sienna Katz's mother, expressed that while nothing will bring her daughter back, the proceedings will at least ensure accountability. Olive Koren's grandfather, Bruce Koren, felt that questions about the investigation remained unresolved, stating, "Today was not just a loss for [the driver]. It was a loss for the truth."
Stranczek is scheduled to return to court later this month.
