(LAPEER TOWNSHIP) -- Lapeer County Sheriff's deputies say a 25-year old Lapeer man was killed in a single vehicle crash late Wednesday along Maple Grove Road, just south of Higley Road in Lapeer Township. An investigation showed that the victim, Robert Stroup, was driving a Ford F-150 pickup truck south on Maple Grove Road around 11:30 p.m. when he failed to navigate a curve and left the roadway. The pickup ended up striking a tree. Stroup's passenger, 25-year old Kala Cowell of Columbiaville was extricated from the vehicle by Lapeer City Fire and Rescue. She was transported to McLaren Lapeer Regional Hospital for treatment of non-life threatening injuries. Stroup was pronounced dead at the scene. Deputies say the roadway was closed for about 3-hours following the crash. Alcohol and excessive speed may have been contributing factors. The incident remains under investigation. Troopers from the Michigan State Police Lapeer Post assisted at the scene.
