A 23-year-old San Diego man was killed late Saturday when he lost control of his car, authorities reported.
The victim, Alfred Jansen, was declared dead at Scripps Memorial Hospital at 12:05 a.m. Sunday, said the San Diego County coroner's office.
Police said the accident occurred at 11:15 p.m. Saturday as the car was traveling at a high rate of speed southbound on La Jolla Mesa Drive. Jansen apparently lost control of the vehicle, which then ran off the road, struck an embankment and overturned.
