Authorities say the wife of a former justice of the peace was the driver of the vehicle used in the killing of a North Texas assistant prosecutor. They say she was a passenger when her husband allegedly later shot a district attorney and his wife.

An arrest affidavit shows Kim Williams implicated husband, Eric Williams, as the shooter of Kaufman County Assistant District Attorney Mark Hasse in January and also District Attorney Mike McLelland and his wife Cynthia last month.

Authorities on Thursday said Kim Williams was the getaway driver when her husband allegedly approached Hasse as he walked into work and fatally shot him. They contend she was a passenger in late March when her husband drove to the McLelland home in the Dallas suburb of Forney.
