The three mustaches return to Long Island to conclude their hunt for the Gilgo Beach Killer. After pulling over a dozen bodies from the sand, the Long Island Police Department were able connect at least 8 of the victims to the same culprit. Unfortunately, interdepartmental feuds and corrupt cops derailed the investigation before the killer could be tracked down. Now it's up to an expert criminologist named Dr Laura Pettler to dig through the evidence and uncover the identity of the culprit before he claims another victim.

The three mustaches grab their bathing suits and sunscreen for a relaxing trip to the beach. And there's no beach more suited for true crime enthusiasts than Gilgo Beach in Long Island. Between 2010 and 2011, nearly a dozen bodies were pulled from the sand, most of whom were young escorts from nearby towns. Early on it was clear to investigators that they were on the trail of a serial killer, and they would have to work fast to track down the killer before they struck again. Kick back, grab a tropical cocktail and join us for the first of our two-part series on the Gilgo Beach Killer.

The three mustaches prepare for their upcoming move by taking a short trip to their soon-to-be home, North Carolina. In 1986, a man named Harold Gentry was brutally gunned down in what appeared to be a botched home invasion. The murder remained unsolved until 2006 when a forensic criminologist named Dr Laura Pettler discovered that Harold's wife, Betty, had a few skeletons in her closet. Specifically, the skeletons of four dead ex-husbands, all of whom died from a gunshot wound under mysterious circumstances. As the old saying goes, "two times is a coincidence, three times is a pattern".
