MOUNT MORRIS TOWNSHIP, Mich. (AP) -- Police say a 25-year-old woman was left severely beaten and naked in a ditch in Genesee County.
Ashley Lucier was listed in critical condition on Friday.
The Flint Journal reports (http://bit.ly/SlGgRO ) some passersby, believed to be students at Flushing High School, covered Lucier and called 911.
Police say there were more than 50 vehicles in the area of the crime scene that were stopped by officers in hopes that someone saw something.
Township Police Chief Scott McKenna says, "this is somebody's daughter."
Police don't know how long Lucier was in the ditch.
