Merrill police are conducting additional patrols while trying to find the vandals who damaged 114 gravestones in two adjacent cemeteries. Investigators say it appears to be a random act of vandalism. They think one or more people did the damage Friday night at Merrill Memorial Park and St. Francis Catholic Church cemeteries. All of the gravestones were pushed or kicked over. Family members were at the grave sites over the weekend looking at the damage. Police have asked people to leave the stones where they are until the investigation is complete.
