A multi-vehicle crash on the 210 Freeway in Glendora left two people dead and prompted the temporary closure of several east and westbound lanes for several hours Thursday morning.  

The crash was initially reported as a solo-vehicle collision about 12:13 a.m. on the eastbound side of the freeway just west of the 57 Freeway, California Highway Patrol Sgt. Kevin Reese said.

Emergency responders headed to the scene received updates that multiple collisions were occurring at the location.  

A total of six vehicles on the eastbound side and a seventh on the westbound side of the freeway ended up being involved in the incident, Reese said.

Two drivers were killed as a result of the additional collisions that occurred, Reese said.

One of those killed was either ejected or struck after getting out of their vehicle. That victim, who has not been identified, was sent into the westbound lanes and then hit by the seventh vehicle involved in the incident, Reese said.

The second person killed in the incident was in a separate vehicle that also crashed on the eastbound side of the freeway. No further details on that crash were given.

Officials closed all but one lane on each side of the freeway at about 12:30 a.m.

The Freeway remained closed for several hours but had reopened as of 7 a.m.

It was unclear what caused the driver to lose control in the initial crash.
