Any one knows what is: asphyxia ?
Asphyxia or asphyxiation (from Greek α- “without” and σφύξις sphyxis, “heartbeat“) is a condition of severely deficient supply of oxygen to the body that arises from abnormal breathing. An example of asphyxia is choking. Asphyxia causes generalized hypoxia, which primarily affects the tissues and organs. There are many circumstances that can induce asphyxia, all of which are characterized by an inability of an individual to acquire sufficient oxygen through breathing for an extended period of time. Asphyxia can cause coma or death.
That’s why he ‘suspected suicide‘ duh?
