Do you think he’s inside a locker? Maybe placed there by other students playing stupid-ass games? Kids are such animals these days, you know...
My CERT team was once called out to assist searching for an elderly Alzheimers patient. The police had been through the house twice. Actually it was the same two cops who had been through the house twice.
"He's not in there. We looked twice."
After a three hour search we finally sent two CERT members in to re-search the house. We found the old man sitting in a closet hiding behind some clothes.
