Contra Costa County Sheriff David Livingston won reelection Tuesday, defeating Richmond Police Officer Benjamin Therriault with a little more than 61 percent of the vote in the race, according to unofficial county election results.

Livingston, who has held the post since 2010, won fairly easily despite publicly feuding with Contra Costa County District Attorney Diana Becton, who also won reelection Tuesday.

Livingston called Becton’s decision to charge sheriff’s Deputy Andrew Hall in the 2018 killing of motorist Laudemer Arboleda “abhorrent,” after Hall was convicted in October of assault with a firearm.

The Prosecutors Alliance of California — of which Becton is a member — responded with a letter to the Contra Costa County Board of Supervisors, asking for more oversight and an audit of disciplinary actions in the Sheriff’s Office.

Therriault, a Richmond officer since 2009, is also the head of the Richmond Police Officers Association. Before that, he was a military policeman in the U.S. Air Force and fought in Iraq. He grew up on the Flathead Indian Reservation in Montana.
