Beyonce pays tribute to Paul Walker at LA concert

Actor Walker died from multiple injuries

After the crash, rescue crews loaded the wrecked car onto a flat-bed tow truck. Several vehicles followed the truck as it left the scene for a tow-yard, where detectives planned to examine it for evidence of what happened in the accident, the sheriff's department said.

When the truck stopped at a traffic light, a man got out of a car, ran up to the tow vehicle and grabbed a panel from the wrecked Porsche Carrera GT, a witness told investigators.

Deputies later found the red, T-top roof panel at a home in the Los Angeles suburb of Canyon Country.

The second man believed to be involved in the theft is a 25-year-old who was outside the state on Thursday but was making plans to turn himself in, deputies said.

Witty was booked on suspicion of felony grand theft and evidence tampering, with bail set at $20,000, deputies said.

Investigators are continuing to seek a cause for the one-car crash.
