You are called to the scene of a possible homicide/suicide. The room where the victim is hanging is locked from the inside by sliding bolts. The windows are also locked from the inside. In the center of the room is the body of the victim hanging by a rope from a ceiling fan. There is no furniture or objects within 20 feet of the victim. Only a wet spot is seen immediately beneath the victim. Is this a homicide or suicide? Explain your rationale.
