SIOUX FALLS, S.D. (AP) — Authorities say an off-duty Sioux Falls police officer cited for careless driving in a crash that killed a 17-year-old Badger girl will not face additional charges. Kingsbury County State’s Attorney Gregg Gass says the July 22 crash was “simply a matter of inadvertent careless driving.” Gass says 25-year-old Cynthia Holmquest was reaching for a pair of sunglasses in her vehicle when it struck Savannah Koistinen’s vehicle from behind, pushing it into the path of an oncoming school bus carrying students. Holmquest pleaded no contest to careless driving in early September. Sioux Falls officials say Holmquest still works for the police department. She was hired in August 2012.
