Authorities say a newly dedicated memorial stone at a grouse habitat in Michigan's Upper Peninsula has been damaged.
The Michigan Department of Natural Resources says the South Marquette County Grouse Enhanced Management Site was dedicated on Sept. 9 to Bill Rollo, a DNR wildlife technician who was instrumental in creating the hunting area that's located near Gwinn.
The 40-year-old died in January and was a 16-year veteran of the DNR. On Sept. 23, the DNR says the memorial stone was knocked off its pedestal when the base of the monument was struck, apparently by a vehicle. A blue paint scrape was found on the monument.
The incident is being investigated by the Forsyth Township Police Department and Michigan conservation officers from the DNR. Tips are being sought from the public.
