MONTEREY PARK (CBSLA.com) — A man was killed in a three vehicle-crash Thursday morning that closed all lanes of the westbound Pomona (60) Freeway in Monterey Park.

The initial accident happened around 2:50 a.m. when a sedan collided with a big rig at the Garfield Avenue exit, the California Highway Patrol said.

“A preliminary investigation is showing us that there were two separate collisions. The first one … where the smaller passenger vehicle collided into the rear of that truck,” Sgt. Bill Preciado said. “Thereafter, the FedEx truck apparently, for unknown reasons, unable to stop, collided into the rear of those two vehicles.”

The driver of the sedan died as a result of the second crash, Preciado said.

One truck driver was transported to a local hospital with minor injuries to his hands and legs.

The CHP reopened the freeway around 6:15 a.m.
