David Antonio Sanchez, 29, killed in single vehicle crash on Interstate 5 in Chula Vista on August 4.

A 29-year-old San Diego man was found dead early Monday after apparently crashing into some trees on an embankment behind a business off Interstate 5 in Chula Vista.

David Antonio Sanchez's car appeared to have veered off the southbound freeway and rolled down an embankment before slamming into the trees and damaging a chain link fence on the back side of an industrial complex at 1095 Bay Blvd., north of Palomar Street, according to police and the county Medical Examiner's Office.

A security officer found the wreckage at around 1:45 a.m., but it was unclear when Sanchez crashed, according to the Medical Examiner's Office. Sanchez was found unresponsive, strapped in the driver's seat.

He was pronounced dead at the scene from "obvious fatal trauma," authorities with the Medical Examiner's Office said.
