Lifeguards and firefighters rescued a person who became stuck on a cliff and suffered serious injuries Tuesday in Torrey Pines. Dispatchers received a call shortly after 4 a.m. from a person who reported that three people were stuck on the beachfront bluffs near the Torrey Pines Gliderport in the 2800 block of Torrey Pines Scenic Drive, San Diego Fire-Rescue Department spokeswoman Monica Munoz said. Personnel responded to the area and found only one person on the cliffs, Munoz said. A fire department helicopter was used to lower a medic in and rescue the stranded person. The victim was airlifted to Scripps Memorial Hospital La Jolla for treatment of serious injuries, she said. No details about the victim were immediately available. It was unclear why the person was on the cliffs or how they suffered the injuries.
