SAN RAMON, Calif. — The wife of an Alameda County Sheriff’s deputy has been arrested in connection with a DUI crash that killed a 3-year-old boy in San Ramon.

The California Highway Patrol said 39-year-old Yarenit Malihan of Pleasanton was behind the wheels of an SUV that rear-ended a stalled Toyota Camry on the side of Interstate 680 Friday night.

The crash killed Elijah Dunn and sent his mother to the hospital with major injuries. His 1-year-old sister and 11-year-old brother suffered less severe injuries.

The family had pulled over after running out of gas.

Malihan was booked for investigation of DUI and gross vehicular manslaughter.

Sheriff’s spokesman Ray Kelly told the East Bay Times (http://bit.ly/2cRJbGy) his department is “heartbroken on both sides” and offering help to the victims and the deputy’s family.
