A man and two teenage boys are facing disorderly conduct charges for allegedly covering two cars and a home with slices of cheese. Pennsylvania state police say the prank occurred in Girard early Saturday. But it’s not clear what motivated it. The names of the three suspects — a 17-year-old Girard boy and two Lake City residents, ages 17 and 18, — have not been released. Authorities say they admitted their involvement in the prank but won’t say why they did it.
