After "hundreds of condoms" were found clogging a sewer pipe in Austin, Texas, police realized that illegal sex may be afoot. A nearby massage parlor was subsequently busted.
Austin police then launched their probe that culminated in a raid about six weeks later where a woman who co-managed the business "was found in a massage room with a completely nude and uncovered male," the document said. Juan Wang and her husband Joseph Emery were arrested on suspicion of managing "a prostitution enterprise that used two or more prostitutes," it said.
Clogged draines was how they caught UK serial killer Dennis Nilsen. But that was human flesh.
