What to Know
Elsa Laremont Stranczek packed her Volkswagen Tiguan SUV with friends on April 18, 2025. The 16-year-old driver reportedly went off the road and struck a tree on San Geronimo Valley Drive. Tragically, four of Stranczek’s passengers died in the crash. Olive Koren, 14, Sienna Katz, 15, Josalynn ‘Josy’ Osborn, 15, and Ada Kepley, 15, died while Stranczek and 14-year-old Marley Barclay survived.
Prosecutors ultimately charged the now 17-year-old Stranczek with vehicular manslaughter. On July 22, 2026, Stranczek appeared in court pleading with a judge to dismiss her case. Now a judge must decide how to proceed.
The case reportedly had challenges from the beginning.
The Marion Independent Journal reported Barclay and Stranczek initially claimed they saw a bright light coming toward them the night of the crash, implying another vehicle may have caused the driver to go off the road. The California Highway Patrol apparently found no evidence backing up that claim.
CHP officers Jonathan Briggs and Erik Carrillo testified they used a recording device the night of the crash when talking to the survivors that was supposed to transcribe the interviews. They later learned the recordings failed. The officers reportedly had conflicting accounts of what the teenagers said, but did not have body cameras the night of the crash. Stranczek ‘s attorney Charles Dresow asked Judge James Chou to dismiss the interviews from evidence.
“If audio existed, then we would know exactly what was said,” Dresow said, claiming the lack of a recording creates a critical issue with the evidence.
Stranczek reportedly broke multiple laws the night of the crash.
Per the Marion Independent Journal, the CHP confirmed Stranczek’s provisional license prohibited her from transporting passengers younger than 20. She allegedly also was speeding the night of the crash.
All six victims were between the ages of 14 and 16 and attended Archie Williams High School in San Anselmo. Chou reportedly will decide whether Stranczek’s charges could be dropped instead of completing rehabilitation. The notion caused mixed reactions.
The victims’ parents don’t share the same thoughts on Stranczek’s future.
Some want the teenager prosecuted to the fullest extent of the law while others believe she made a mistake that deserves grace.
Sienna Katz’s mother, Margaret Minicozzi said Stranczek changed the course of her life forever and nothing will ever be the same. She wants the teenager to face the consequences of her actions.
“It is how they learn integrity and become responsible adults,” Minicozzi said.
She added that she does feel empathy for the teenager. “I do not want her to suffer more than she has,” Minicozzi said. “I hope she learned from this tragedy, but I sincerely hope my daughter’s death was not in vain.”
Gail and Bruce Koren, grandparents of Olive Koren, said their granddaughter would not want her friend to have any further punishment.
“This is her legacy of how she cared for people,” they said.
Jessica Glantz, Marley Barclay’s mother, agreed. She said that both she and her daughter believe the driver deserves diversion for rehabilitation.
“This was a horrible tragedy born from an accident, not from malice,” Glantz said. Her daughter, who suffers from survivor’s guilt, added, “There’s not a single day when these girls do not leave my mind.”
