Kentucky State Police said James Whisman and Jesse Sebastian slipped away from the Western Kentucky Correctional Complex in Fredonia on Aug. 18.
WPSD-TV in Paducah reports that Principal Glen Ringstaff reviewed surveillance video from the Caldwell County School Campus in Princeton and found the men had twice broken into the school building.
When Ringstaff documented two intruders late at night, he called the Kentucky Department of Corrections and officers identified them as Whisman and Sebastian.
School Superintendent Carrell Boyd said video showed the men inside the building on Wednesday and again on Sunday. Food was missing from the cafeteria both times.
