History & local legend
Conemaugh Valley Junior/Senior High School near Johnstown has stories passed from custodians to pupils. In a June 2010 account, a student said janitors had described a rotten apple flying at someone inside the school and chalk handprints appearing on her back.
The student also recalled lights going out during practice and finding a friend's locker open the following morning. A year later, another commenter recognized the apple story after hearing it from a friend, showing how the tale circulated among students.
Other custodial accounts were quieter: whistling or humming heard while the building appeared empty.
