Culbreath's arraignment has been postponed several times now.
The Feb. 9 crash happened about 4:45 a.m., while Culbreath was driving her 2013 Chevrolet Camaro at speeds approaching 100 mph, according to the California Highway Patrol.
Culbreath somehow got on the southbound Orange (57) Freeway going north, then transitioned to the westbound 60 going east, where the Camaro crashed head-on into a 1998 Ford Explorer north of Diamond Bar Boulevard, according to the CHP. A 2006 Ford Freestyle then slammed into the Explorer.
Culbreath's 24-year-old sister, Maya, and another passenger, Kristin Young, 21, of Chino, died in the crash, along with four people ejected from the Explorer. They were identified as Huntington Park residents Gregorio Mejia- Martinez, 47, Leticia Ibarra, 42, Jessica Mejia, 20, and Ester Delgado, 80.
Culbreath was taken to Los Angeles County+USC Medical Center in serious condition with a fractured femur and ruptured bladder, according to the CHP, and was treated in the hospital's jail ward before being moved to the Twin Towers Correctional Facility.
Culbreath faces a maximum life prison sentence if convicted of the murder charges.
Culbreath was convicted of driving under the influence on April 13, 2010, when she was 17, according to Department of Motor Vehicles records. She was stopped for two more violations before her license was reinstated in December 2011, according to the DMV, which lifted restrictions on her license just a week prior to the deadly crash.
Her sister Maya had multiple convictions for drunken driving and her
license had been revoked, according to the DMV.
