Is it possible that ~
1. He died of heart attack. Beng Hock had weak heart and was intimidated by MACC interrogation, can't stand the stress and died. But how did he end up at the 5th floor of the building (he was supposed to be at the 14th)?
2. He fell off MACC building (Plaza Masalam) during 'prison break' attempt. But it was just an interrogation, he wasn't jailed or prisoned, so this doesn't make sense to escape as well.
3. He slipped and somehow flied through the window and fell off the building. Slippery floor, banana pile?
