The Los Angeles County coroner has officially ruled Sarah Alarid's death an accident five days after the 19-year-old Canyon Country woman was found near her crashed car in a ravine.
Ed Winter, an assistant chief coroner, said Monday an autopsy showed Alarid died of "multiple blunt force injuries" from a car accident.
She went missing New Year's Day, when she was last seen leaving a party.
Friends and relatives spent more than a week looking for her until sheriff's deputies in a helicopter on their way to another call spotted her car early Wednesday off Sand Canyon Road in the Angeles National Forest.
Her body was found near the car, having apparently been ejected after the car went several hundred feet down a hillside off the windy road.
Because detectives were initially unsure whether Alarid's death was related to a shallow grave found in Big Tujunga Canyon, they placed a "security hold" blocking the coroner from releasing any information about Alarid last week.
But after investigating, detectives said they didn't believe there was foul play. They lifted the security hold and and turned the crash investigation over to the California Highway Patrol.
A spokesman at the CHP's Newhall office said the cause of the crash is still being investigated. Winter said the results of toxicology tests on Alarid won't be available for at least a month.
