The collision occurred at about 3:29 a.m. in the eastbound lanes just west of the Via Verde Street off-ramp, a CHP officer told City News Service. First responders pronounced one person dead at the scene. The person's name, age and gender were not immediately released, and the CHP had not said what led to the crash.

A SigAlert shut down the left four eastbound lanes. The closures continued into the morning commute, with eastbound traffic on the 10 Freeway backed up to Barranca Street, MyNewsLA reported. All lanes were cleared and the SigAlert was cancelled at 8:23 a.m., the CHP reported.

A separate report based on the CHP incident log put the first reports at about 3:28 a.m. and described vehicles blocking several lanes, including the HOV lane, in the first minutes after the collision.
