LOS ANGELES (CBSLA.com) — Los Angeles County supervisors Tuesday approved a $10,000 reward for information leading to the second driver accused of racing on I-5 and triggering a fiery crash that left three people dead and two others injured in Commerce.

The wanted suspect was driving a Dodge Charger and racing against a Dodge Challenger driven by 35-year-old Dealio Lockhart of Whittier, according to the California Highway Patrol. Lockhart remains in jail on $1 million bail and faces three counts of vehicular manslaughter among other charges.

Supervisor Hilda Solis recommended the reward. “Detectives assigned to the case have identified and arrested the driver of one of the vehicles engaged in the speed contest causing the collision, however, they have not received any viable clues regarding the identity of the second vehicle which fled the scene,” Solis said.

The race set off a chain-reaction crash that killed Brian Lewandowski, Michelle Littlefield, 19, and UPS driver Scott Treadway, 52, early Saturday morning.

The CHP said the Challenger clipped a UPS big rig, sending it into the air and causing it to shear off the top of a gray Nissan, which was carrying Lewandowski and Littlefield and two others. They were returning after spending a day at Disneyland.

The driver of the Nissan, 21-year-old Tony Miramontes of Van Nuys, is in a coma at St. Francis Medical Center in Lynwood. A fourth person in the car was Alfonso Morillo who remains in critical condition.
