The study from Texas State University done in partnership with the Austin Police Department found neither direct evidence nor indirect warning signs of a serial murderer.

Texas State's report reviewed similar rumors of serial killers who drowned their victims, including the Smiley Face murderer, the Manchester Pusher and the New England serial killer. Each of those were "debunked as urban myths," the report said, adding all of them included alcohol presence in victims as well as bars located near waterways.
