A 43-year-old Long Beach woman died after a hit-and-run crash on the southbound 710 Freeway in Long Beach early Monday morning, according to a news release from the California Highway Patrol.

The CHP said the woman had been involved in a collision that left her car disabled around 3 a.m. on the 710 just north of the 405. After that collision, she got out of her car and ran westbound across traffic lanes where she was struck by an unknown vehicle. The driver of that vehicle fled the scene before authorities arrived, according to the CHP.

Soon after, a second driver in a Kenworth semi-tractor also struck the woman as she was lying in the roadway. That driver stayed at the scene, according to the CHP.

Medical crews determined the woman was dead shortly after the crash, the CHP said. Authorities haven’t yet publicly identified her. No arrests have been made.

The CHP is investigating both collisions and is trying to figure out why the woman ran into traffic.
