Olivia Culbreath

Olivia Carolee Culbreath, 26, of Fontana, was driving 100 mph northbound in the southbound lanes of the 57 Freeway and then eastbound in the westbound lanes of the 60 Freeway, where her 2013 Chevrolet Camaro collided head-on with a Ford Explorer.

Three generations of family members in the Explorer were killed: Huntington Park residents Gregorio Mejia-Martinez, 47; Leticia Ibarra, 42; their daughter, Jessica Mejia, 20; and her grandmother, Ester Delgado, 80. Culbreath’s 24-year-old sister, Maya, and one of Culbreath’s friends, Kristin Young, 21, of Chino, also died in the crash. Culbreath was injured but was the only one to survive.
