A retired NYPD detective has been working the same case for 27 years. He has identified over 700 potential victims. The FBI says they all drowned by accident. 1997 New York City Patrick McNeill was 21 years old. He stepped outside a bar to wait for a ride home. He was never seen alive again. The detective who caught the case examined the autopsy. Binding marks on the wrists. The body showed signs of being in the water for far less time than McNeill had been missing. He swore to the family he would keep investigating. Over the next decade, they found the pattern. Young men, athletic, college-aged, last seen leaving bars at night. Found drowned in rivers days or weeks later. Ruled accidental every time. Near at least a dozen body recovery sites, someone had spray-painted a smiley face. GHB, the date-rape drug, was found in multiple victims. But GHB testing is not routine in drowning autopsies. Dozens of victims were never tested for it at all. Dakota James disappeared in Pittsburgh in 2017. He was missing for 40 days when his body was pulled from the Ohio River. Almost no decomposition. 40 days no decomposition. His body had been somewhere else. The coroner ruled accidental drowning. In Minneapolis, Chris Jenkins disappeared on Halloween 2002. His death was reclassified as a homicide in 2020.
