The crash killed a three-year-old boy and severely injured the boy's mother.

On June 7, Malihan was involved in another alleged DUI crash in Pleasanton. In that crash, one of Malihan's children was in the car at the time, according to sources cited by KPIX 5.

Following a delay for blood work to be completed, the Alameda County District Attorney's office filed misdemeanor charges of DUI and child cruelty on July 27.

There have been no formal charges against Malihan in the latest crash. Her family was able to get her released from custody on bail.
