DIAMOND BAR (CBSLA.com) — Authorities say a 21-year-old woman is under arrest on suspicion of felony DUI and felony manslaughter after a wrong-way crash in Diamond Bar claimed six lives.

The suspected wrong-way driver, identified as Olivia Carolee Culbreath of Fontana, sustained a broken femur and ruptured bladder following the early morning collision on the westbound 60 Freeway north of Diamond Bar Boulevard.

Authorities say Culbreath, 21, was allegedly behind the wheel of a red Chevy Camaro that initially entered the 57 Freeway prior to transitioning to the 60 Freeway.

The vehicle, which had two other occupants inside, was allegedly heading east in the westbound lanes. Both occupants were killed.

Culbreath was taken to a hospital where she was listed in stable condition and expected to be charged.

“The officers had sufficient evidence and believe that she was impaired at the time,” CHP Officer Rodrigo Jimenez told KNX 1070’s Ed Mertz.
