SAN DIEGO -- Three people were killed Thursday in a fiery multi-vehicle crash on Interstate 805.

Flames were seen leaping from at least one vehicle after the collision, which was reported around 4:35 p.m. near La Jolla Village Drive and Miramar Road in the Sorrento Valley area.

Three people were killed and one person was seriously injured, officials confirmed. The injured person was taken to Scripps Memorial Hospital in La Jolla, San Diego Fire-Rescue Department said.

Caltrans closed all northbound lanes on the freeway.

Witnesses reported a wrong-way driver speeding along a stretch of highway near the site of the crash shortly before the accident, California Highway Patrol told FOX 5.

CHP investigators were at Ashley Falls Elementary School in Carmel Valley, where, shortly after 4 p.m., witnesses say a black McLaren smashed through a fence and sped out of the campus parking lot. Investigators are looking into several other incidents involving the luxury sports car, but officials did not say whether the incidents are connected to the deadly freeway crash.

By late Thursday, the two far right lanes of northbound I-805 along with the westbound Miramar Road and eastbound La Jolla Village Drive on-ramps to northbound I-805 had reopened to traffic.
