Another one of the passengers in a vehicle that slid off of Interstate 205 outside of Tracy early Saturday morning has died.

Clayton Lamb, a 17-year-old Manteca resident, was a passenger in the 2006 BMW that was carrying six passengers – only one of which was 18 – back from San Francisco when the driver reportedly fell asleep and went off of the road, down an embankment, and into a tree.

After being declared legally brain dead on Monday, Lamb’s family made the decision to call in the organ harvesting team. He was eventually taken off of life support, according to a Stanislaus County sheriff’s deputy assigned to the coroner’s office. An online petition to raise money for his family had raised almost $9,000 of the $10,000 goal to help the family – which has five children – with expenses incurred prior to his death. 

The vehicle’s driver, 16-year-old East Union student Cheyenne Uecker, was killed at the scene. At least two other passengers are still in area hospitals with varying degrees of injuries. Terha Brown, 17, was airlifted to UC Davis Medical Center in Sacramento where, according to family members, doctors determined that she was paralyzed from the waist down. Joey Hrenko, 18, and Shelby Culis, 17, are currently at Memorial Medical Center in Modesto in stable condition. 

The only surviving passenger of the crash that was wearing her seatbelt, 17-year-old Jessica Guillory, is still in the intensive care unit at San Joaquin General Hospital in French Camp. Her condition was last listed as serious. 

The exact cause of the crash is still under investigation by the California Highway Patrol. According to the agency, the vehicle went off the road shortly after 5 a.m. on Saturday morning. It was dark on the stretch of I-205 just west of Tracy Boulevard and the roadways were dry.
