There's no way the current could have carried Patrick 12 miles down the river. Gannon thought someone, possibly the person in the van spotted that night, abducted and killed Patrick, drove to Bay Ridge, and left his body in the water. The detective needed to track down that van.

Thankfully, witnesses gave him a partial license plate number, but when Gannon took it to his supervisors, they told him identification would be too costly for the department. With that, his case hit a dead end. During the course of his investigation, Gannon grew close to Patrick's parents. He told them he believed foul play was involved, and he vowed to get justice for their son.

Eventually, Gannon was taken off the case and reassigned, but he didn't forget about Patrick, especially not when over the next 15 months, two more young men died the exact same way. On December 31, 1997, 22-year-old Lawrence Andrews Jr. took the train from his home in Brewster, New York, to Grand Central Station in Manhattan.

Larry, as he was known, had plans to attend Times Square's New Year's Eve ball drop, a yearly tradition for him and his friends. But shortly after midnight, Larry got separated from his group. He was spotted an hour later by a different group of friends having a drink in Grand Central Station. He was last seen around 2 a.m. walking west on 42nd Street.

Six weeks later, Larry was found dead in Bay Ridge, in the same waters Patrick had been found 10 months prior. Medical examiners concluded his cause of death was drowning, but again couldn't determine how he got there. Just as he did in Patrick's case, Detective Gannon consulted with the NYPD Harbor Unit to get information on water currents. And again, it didn't add up.

Typically, when someone drowns, their body is recovered within 100 yards from where they fell into the water. Larry somehow floated nine miles down the river. More suspiciously, he was found just a few yards away from where Patrick had been found. Were they both kidnapped, killed, and left in the exact same waters? A few months later, it happened again.

On May 17th, 19-year-old Joshua Bender's body was found in the Hudson River near 138th Street in Harlem. Joshua was a student at Yeshiva University and a volunteer with the Ambulance Corps. He'd gone missing two weeks prior, but much less is known about the circumstances of his disappearance than those of Patrick and Larry.

He was last seen in his dorm, three miles away from where the body was found, studying for a final exam. As his mother would later say in a press conference, it seems as though he has vanished into thin air. But the conclusion was much the same. Accidental drowning, with no idea how he ended up in the water...

Kevin Gannon didn't work on Joshua's case, but he did notice the similarities to Patrick and Larry's deaths. He continued on in his career until he retired from the force in 2001. But he wasn't done. About a year later, he turned on the news to find his suspected serial killer was on the move.

In October 2002, retired NYPD detective Kevin Gannon learned that over the course of 10 days, several people in Minnesota and Wisconsin had gone missing. The cases involved promising young men, a lot like Patrick O'Neill, Larry Andrews, and Joshua Bender. Gannon passed along information to the agencies involved in the drownings, then called his former partner, Tony Duarte.
