Gilgo Beach serial killer Rex Heuermann has admitted to murdering eight women, bringing some closure to the case that has terrorized Long Island for more than three decades. Standing inside Suffolk County Court on Wednesday, the hulking architect, husband and father finally admitted to killing Melissa Barthelemy, 24, Megan Waterman, 22, Amber Costello, 27, Maureen Brainard-Barnes, 25, Jessica Taylor, 20, Sandra Costilla, 28, Valerie Mack, 24, and Karen Vergata, 34, during a reign of terror between 1993 and 2010. In a matter-of-fact tone, the 62-year-old - wearing a dark suit, white shirt and blue pattern tie - casually uttered the words 'guilty' to seven murder charges and admitted his guilt of an eighth. #rexheuermann #giglobeach
