The Barron County Sheriff’s Department is investigating the shooting deaths of two 55-year-old adults and a teenager Friday night.  A 9-1-1 call was received at about 9:00 p-m from a female asking for help.  Investigators say the bodies of John Hengst and Brenda Turner, both 55 years old, were found in the home in Chetek, along with 17-year-old Natalie Turner.  All three were shot, though deputies won’t confirm a cause of death until autopsies are completed.  Sheriff Chris Fitzgerald says there is no danger to the public.
