Even if the engine was switched off the helicopter should have auto-rotated somewhat, not fallen straight down… would have had to have been a failure in a rotor component that caused it to lose lift instantaneously.

Still, the fact that it hit the hotel lends itself to some kind of a controlled-failure. Explosives on bolts for the collective (up/down lift) controls maybe.

Youre right… my bad, Hotel GM was on helicopter. So could have been sabotage of a part before takeoff.

Takes off, something breaks, loses collective control, collective goes negative lift and it drops like a stone.
