Rescuers hiked though rugged terrain near the Mexican border Sunday to reach the remote site where a private jet went down after taking off from San Diego, killing all five people aboard.
The Learjet was being used as an air ambulance, carrying two pilots, two paramedics and a nurse on a flight bound for Albuquerque, N.M., when it crashed.
The plane went down at about 12:30 a.m. Sunday in a mountainous region near a small San Diego airstrip, said Larry Levy, chief executive officer and medical director of Albuquerque-based Med Flight Air Ambulance, which owned the aircraft.
Emergency personnel had located three bodies by late morning, a San Diego County Sheriff's Department spokesman said.
The cause of the crash had not been determined.
