The recovery of Noah Eno's body from the Chicago River on June 17, 2023, has sparked fears of serial killers terrorizing the city as ten men and six women have been pulled from the water and Lake Michigan since last year. While officials have yet to determine the manner of death, the uptick in bodies found floating in the Chicago River has fuelled theories surrounding the involvement of the Smiley Face Killer.Most of these theories were explored by Reddit and TikTok sleuths who are growing increasingly resolved in their belief that the Chicago drownings are the work of a serial killer. However, law enforcement has shot down the swirling rumors online, stating the deaths are not connected.Image via Screengrab/SportsKeedaMeanwhile, after six bodies were fished out of the river this year, online sleuths have renewed interest in a theory about Smiley Face Killer targeting young men across the city. While law enforcement dismissed theories of a serial killer roaming the city, a dismayed Reddit user said:“It is the worst feeling when you've learned enough about SFK (smiley face Killer) to be able to pinpoint which missing men are going to end up deceased in the water... has happened to me 5+ times in 2023 so far.”Image via Screengrab/RedditAnother user complained about the decreased reporting on Smiley Face Killers.“You just sometimes have to dig for the info because the reporting on SFK cases is laughably poor.”Image via Screengrab/RedditHowever, the coverage relating to smiley face Killers is sparse due to the theory being debunked by law enforcement officials and the lack of concrete proof to support the swirling rumors.What we know about the Smiley Face Killer and the connection to Chicago drownings🤌🏼Super Nintendo Chalmers🤌🏼@snchalmers79@wapella @nbcchicago The “smiley face killer” is a newish urban legend that has attracted the attention of detectives or retired detectives.

It’s been around for maybe 20 years, before social media became so prevalent.The genesis of the term Smiley Face Killer can be traced back to the 1970s after three young men, aged between 18-24, were found floating in the city's river around the same time.Sometime in the 1970s two retired New York City detectives, Kevin Gannon and Anthony Duarte, and criminal justice professor, Lee Gilberton endorsed the Smiley face murder theories. Gannon, Duarte, and Gilbertson also helmed a docuseries on Oxygen about this theory, titled 'Smiley Face Killers: The Hunt For Justice,' in 2018.Oxygen True Crime@oxygenHundreds of young men found drowned across the country.

Gannon believed that the killings are not the work of one man but a concerted effort of a group of killers who follow a similar pattern. Gannon told Newsweek:"The group is actually leaving symbols behind letting you know, 'Yes this was us, come and catch us."Though the official cause of death was believed to be an accidental drowning, Gannon told CNN in 2008 that he believed the men were drugged and abducted from bars, before being killed and dumped in the water.While Gannon told Newsweek he has not investigated the reports of recent bodies discovered in Chicago, he believed they are connected and the work of a serial killer.What we know about the Chicago drownings this yearCarol Van Tuyle@TuyleCarol36351Noah Enos update.There is going to be a candlelight vigil on Friday, N.
