Josephus A. Havenith was a Dutch citizen living in Munich, Germany, where he taught music. On Feb. 25, 1980, Havenith had been at the Fort Harrison Hotel for two months taking counseling and following a regimen of vitamins and minerals prescribed by Scientology. A maid said Havenith left a note on his door -- Room 771. It read "sleeping," so he was not disturbed until later in the day when other guests discovered that the carpet outside his room was soaked. Inside, the hot water was still running in the tub.

At the time, church officials and police told reporters that Havenith was in his "50s or 60s" and was found dead in bed. In truth, Havenith was found by the maid lying dead in the bathtub. The water was so hot it had taken the skin off of his body. No one is certain when he died. An autopsy report lists his death as "probable drowning" but notes that his head was not under water. In 1980 when Havenith died, Florida officials had little knowledge of the vitamin and mineral programs used by Scientology.

"Is it possible that given whatever was going on in his body, getting into hot water did something?" asks medical examiner Wood in reviewing the case. "Perhaps." With no evidence of a struggle in his room or other foul play, Wood said she had to presume that some sudden event occurred involving his heart or his diet. "We'll never know what happened, the questions remain unanswered," she said.

His body was cremated and shipped home to the Netherlands at the expense of the Church of Scientology. Family members could not be located.

Note the most disturbing part:
His death was 'Probable drowning', but his head was not, and never was, submerged.
