After a body was found floating in a San Antonio sewage tank Saturday, online speculation has tried to link the discovery to a separate corpse found in Corpus Christi — and blame both deaths on a serial killer. Law enforcement officials in San Antonio and Corpus Christi have said there’s no evidence of foul play in either death, much less a connection between the cases. Even so, the rumor mill has taken off, reminiscent of speculation around Austin’s “Rainey Street Ripper,” who internet sleuths say is responsible for a number of bodies discovered in and around Lady Bird Lake.
