John,
Also the boy fell off the roof of the dormitory
which had an entranceway from the dorm itself
He did not fall from the tower.

John Black,
I was a student there in 68 and 69.The child who fell or was pushed off the roof was not a student but a summer camper.The case remains open and if you look at some links on other sites you'll see that there is still some interest in solving the mystery
