A 77-year-old woman died after a violent crash tore through the door of the Tesla she was riding in, throwing her into lanes of the 405 Freeway in Long Beach, according to the CHP.

The crash happened around 9:40 p.m. Monday, April 15, on the southbound 405 at Lakewood Boulevard, the CHP said in a statement.

For some reason, the Tesla’s driver swerved and hit a curb at the end of the Lakewood Boulevard on-ramp, according to the CHP. The driver then lost control and hit an empty Chevy that was stopped on the right shoulder, the statement said.

That collision tore through the Tesla’s right rear-passenger door, ejecting the 77-year-old woman, the CHP said.

She ended up in the No. 5 lane of the freeway where a BMW hit her, killing her, according to the CHP.

Authorities are still investigating what caused the crash, but everyone involved stayed at the scene, and nobody was arrested, the CHP said.

The 78-year-old man driving the Tesla and another passenger, a 73-year-old woman, suffered minor injuries in the crash, but they declined medical treatment, the CHP’s statement said.

The CHP identified the woman killed in the crash as Judith M. Blankenfeld, a resident of Hawaii. She didn’t appear to be wearing a seatbelt, according to the CHP’s statement.
