Two 20-year-old men from Marin were killed in a five-vehicle freeway wreck in Pasadena.

Tristan Lee Witte, a San Rafael resident, was at the wheel of a Buick that was crushed during the pileup Friday on Interstate 210. He was pronounced dead at the scene.

His passenger, a 20-year-old Novato man, was also found dead in the wreckage. The coroner’s office in Los Angeles County did not release his name Sunday because his identity was still being confirmed.

Witte was a 2014 graduate of Marin Academy, where he was an athlete and musician. He went on to Harvey Mudd College in Claremont, where his activities included working as a peer consultant for writing workshops and leading orientation excursions for new students.

The crash occurred shortly before 5 p.m. Friday, when a box truck collided with a Jeep Cherokee in the eastbound carpool lane, the California Highway Patrol said. The impact pushed the Jeep into the Buick that Witte was driving.

The box truck then struck the Buick, pushing it into a collision with a Chevy CMC, police said.

“This impact caused the Buick to fold in half causing fatal injuries to the driver and passenger of the Buick,” the CHP reported.

The box truck then struck the GMC, causing it to flip on its side. The Jeep was broadsided by a Hyundai.

Four people were taken to the hospital for treatment of minor injuries.

The cause of the crash is under investigation. The CHP does not suspect intoxication as a factor.

The driver of the box truck was identified as Gabriel Lopez, 45, of Corona. The driver of the Jeep was Tyler Brubaker, 26, of Valencia. The driver of the Chevy was Reggie Pena, 55, of Perris. The driver of the Hyundai was Meredith Lee, 36, of Ventura. —— (c)2016 The Marin Independent Journal (Novato, Calif.)
