Authorities say five of the six people killed in an Arizona bus crash were California residents, and all were Mexican citizens.

A medical examiner on Wednesday said two lived in Bakersfield, Calif.: 56-year-old Hermalinda Roman De Hernandez and Margarita Roman DeHaro, age unknown.

Margarita Banuelos was 58 and lived in Los Angeles, and Maria Del Refugio Gonzales, age unknown, lived in Van Nuys, Calif.

The only man killed was 85-year-old J. Nicanor Rodarte Hernandez of Temecula, Calif. The lone Mexican resident was 68-year-old Eusevia Valerio Rios of Durango, Mexico.

The bus was headed to Los Angeles from the central Mexican state of Zacatecas on Friday when it hit a pickup on Interstate 10 south of Phoenix and rolled.

Sixteen passengers were also injured.
