Four months after an SUV catapulted off a cliff along Highway 1 in San Mateo County — an incident captured in a widely-circulated, horrifying video — officials have identified the woman who died behind the wheel.

The California Highway Patrol said on Wednesday that officials have confirmed the driver of the 2007 Lexus SUV was San Francisco resident Tracey Ivori Sinclair. Investigators used a missing person’s report, DNA match and driver’s license to solve the case.

Officials have been investigating the crash since it happened shortly after 10:30 a.m. Dec. 30, 2019, along the scenic coastal drive south of Gray Whale Cove. The dash-cam of a passing car happened to capture video that shows the SUV driving straight and launching off the cliff instead of curving with the road.

It remains unclear what caused Sinclar to veer off the road.

The crash prompted air, land and water search crews from multiple agencies, including CHP, the U.S. Coast Guard, San Mateo County Sheriff’s Office and fire officials. Rough, cold waters forced them to suspend the search the evening of the incident without locating the body or car.

In the following months, CHP investigators discovered human remains and a California drivers’ license on Montara State Beach that belonged to Sinclar. The coroner’s office matched the DNA evidence to Sinclair.

A search of the Department of Motor Vehicles database showed Sinclar was the registered owner of a 2007 Lexus SUV. Investigators also discovered that Sinclair’s family had filed a missing person’s report.

“The San Francisco Area CHP would like to express our heartfelt condolences to the victim’s family and friends,” officials wrote in a statement. “Finally, we would like to thank the public for your support, patience, and assistance throughout this ongoing process.”
