A man who was outside in the rain without an umbrella or hat didn’t get a single hair on his head wet. Why?

A wealthy man lives alone in a small cottage. Being partially handicapped he had everything delivered to his cottage. The mailman was delivering a letter one Thursday when he noticed that the front door was ajar. Through the opening he could see the man's body lying in a pool of dried blood.

The police officer suspects it was foul play. Who does he suspect and why?
