The L.A. County Sheriff's Department tonight ID'd that suspect as 18-year-old Jameson Witty of Tujunga:

He was collared about 11:30 a.m. today, according to sheriff's inmate data.

A statement from the department's Santa Clarita Station says deputies armed with a search warrant for his residence nabbed Witty as he was leaving home.

A second suspect, a 25-year-old who is outside the state, was talking to cops about turning himself in, sheriff's officials said.

The tow truck was assigned to pick up the wreckage and take it to an impound yard for futher investigation, deputies said. The remains of the Carrera GT were being hauled off about 10 p.m. Saturday, they said.

The driver noticed “several” vehicles following the truck as it headed east on Newhall Ranch Road, according to the Sheriff's Department. Here's what happened next, according to that statement:

At one point the driver of the tow truck stopped at the red light E/B Newhall Ranch Road at McBean Parkway. A witness saw a male exit a vehicle that was following the tow truck. The male grabbed a piece of the wrecked Porsche off the tow truck bed. The male drove away with the stolen vehicle part. The tow truck driver reported the theft to the Santa Clarita Valley Sheriff's Station.

The part was described as one of the red Porsche's removable roof pieces, known as t-tops, cops said.

Sheriff's detectives say they'll recommend charges of grand theft and tampering with evidence. Witty was being held in lieu of $20,000.

Walker died Saturday afternoon after his friend, Roger Rodas, took him for a spin around Valencia in the exotic sports car.

The Porsche might have split apart. It definitely went up in flames. And Walker, a 40-year-old best known for his role in the Fast and the Furious franchise, and Rodas, were dead at the scene.
