A bowling coach in Monroe County shot and killed a 17-year-old girl who was on the Bedford High School bowling team, investigators said, but the motive is still unknown. Monroe County Sheriff Troy Goodnough said Wednesday 33-year-old Ryne Leist, of Temperance, allegedly shot and killed 17-year-old Gwen Smith at her step father’s home on W. Sterns Road on June 14. The sheriff said Leist “made entry” into the home and shot the teen multiple times.
