3 Youths Killed, 2 Others Hurt in Sports Car Crash : Tragedy: Their late-model Jaguar flipped over at high speed, witnesses said. The victims are believed to be area participants in a weekly pickup basketball game.

Three youths were killed and two others injured Saturday when a speeding late-model sports car flipped over and crashed, authorities said.

Two of the dead were ejected from the blue four-door Jaguar sedan at the accident scene in the hills about five miles east of Interstate 5. The third, a juvenile, was found inside the car, San Clemente police said. None of the three had been positively identified by late Saturday, and the names of the two injured boys were being withheld pending notification of relatives.

One of the injured youths, a 17-year-old boy believed to have been behind the wheel at the time of the 12:18 p.m. crash, suffered a concussion and cannot remember the accident, according to officials at Mission Community Hospital in Mission Viejo. Both he and an 18-year-old male were conscious and listed in fair condition.

“He asked me how he got in the hospital,” a nursing supervisor said of the younger boy. “He doesn’t even recollect what happened.”

Preliminary information indicates that all five were San Clemente area youths who gathered each Saturday morning for a pickup basketball game, but may have known each other only by first names, authorities said.

San Clemente Police Lt. Paul Falk said two of the dead are believed to be brothers, but he said it may be Monday before all are positively identified.

Investigators said the accident occurred on Avenida La Pata, about three miles east of Calle del Cerro, on the road leading to the TRW test site. It is an area where housing developments are under construction.

Falk said security guards patrolling a grading site in the area told police they saw the Jaguar traveling “at a high rate of speed” along a straight stretch of road, when it suddenly lost control and flipped over on a dirt shoulder.

No evidence of alcohol or drug use was found at the crash site, he said. Autopsies on the bodies are pending.

It was unclear what relationship the owner of the Jaguar had to the five youths. Someone may have allowed one of the boys to use the car, but two detectives brought in just to handle that end of the investigation were still trying to confirm that, said Falk.

Detectives interviewed the injured youths, but had trouble Saturday getting information, officials said.
