Ok, heres what you do on the first floor go through the double door where you found the first hole.
Facing the door you came in from go through the door on the right and make your way to the top becarefull there are bats flying all around the area.
When you reach the roof go in the door and go to the big steel wheel then exit and find your way into the middle of the compound.
Then climb the ladder up into the area where you can turn the cells and line up the cells with the bloody beds.
Only the second and third floors can be turned.
