SAN PABLO (CBS SF) — A Sacramento man being held in a fatal East Bay hit-and-run crash that killed four and injured six others has been charged with four counts of murder, prosecutors said.

The Contra Costa District Attorney’s Office said Fred Lowe was facing seven counts in the horrific weekend crash on I-80 near San Pablo Dam Road.

He has been charged with four counts of murder in the deaths of Daryl Horn, 50, and Joseph Horn, 14, both of Napa, and Troy Biddle, 52, and Baden Biddle, 12, both of Bainbridge Island in Washington.

Lowe also was charged with driving under the influence with a special allegation, driving with a blood alcohol level of .08 causing great bodily injury within 10 years of two other DUI convictions and leaving the scene of an accident.

In a statement sent to KPIX 5 by the Horn and Biddle family, they offered their thanks to investigators and first responders.

“The Horn and Biddle family would like to thank all of the individuals, first responders and agencies that have been involved in the process that led to these charges being filed,” the statement read. “The families have complete faith that the legal system will run its course and justice will be served. The top priority for the families will continue to be united in sharing their deep love for each other and remain focused on the wonderful memories of their loved ones who are so sorely missed.”

The 47-year-old Lowe was expected to be arraigned on the charges Thursday.

He allegedly was driving under the influence on westbound Interstate Highway 80 when he triggered a crash involving five other vehicles at 8:11 p.m. Saturday.

The car carrying the Horns and Biddles flipped over. A fifth passenger in the vehicle — University of California pitcher Jared Horn — survived but did suffer injuries.

“We cannot imagine what Jared is going through right now, and the thoughts and prayers of our entire Cal baseball community are with Jared and his family,” Cal baseball head coach Mike Neu said in a statement.

“Jared is a respected and beloved member of our team as well as an incredible student-athlete, teammate and friend. We will give him any and all support that we can as he goes through this unthinkably difficult time.”

Five others were injured in the crash and required hospitalization.
