Police in New York City have revealed they are exploring potential links between Gilgo Beach serial killer suspect Rex Heuermann and other unsolved murders outside of Long Beach. An NYPD official told ABC News the 59-year-old is being looked at in connection to missing persons cases and murders across all five boroughs of New York City. The married father-of-two’s DNA has been entered into a statewide database and his alleged MO is being compared to other cases – including those during the period he was allegedly active in Gilgo Beach. Mr Heuermann is charged with the murders of three women who vanished between 2007 and 2010, and is the prime suspect in a fourth murder. It’s not clear whether he committed any more alleged crimes between the discovery of the bodies in 2010 and his arrest 13 years later. He lived close to Gilgo Beach in Massapequa Park but worked in the heart of Midtown Manhattan where he runs an architecture firm. He also has ties to South Carolina and Las Vegas, owning properties in both locations. Mr Heuermann’s attorney released a statement on Monday, insisting he is innocent and that officials have ignored “more significant and stronger leads”.
