The dirtiest killer of the year was the man private investigator Ed Rivers had to save from the chair. Wally Tulman, Florida socialite, had been convicted of molesting and murdering a young girl. Tulman’s lovely wife begged Rivers to take his case - to prove him innocent. Rivers wouldn’t touch it with a ten-foot pole. Then somebody tapped him over the head, just to make sure. Ed Rivers got the message. Somebody didn’t want him on the case. So he waded into it - with both fists flying.
