  • Rex Heuermann, a Long Island architect, is expected to plead guilty to eight homicides related to the Gilgo Beach serial killings during a court appearance on Wednesday.
  • Heuermann was arrested in July 2023 after DNA from a discarded pizza crust linked him to the 2010 murder of Megan Waterman, and subsequently to other victims.
  • Prosecutors allege Heuermann is responsible for the deaths of seven women: Melissa Barthelemy, Maureen Brainard-Barnes, Amber Lynn Costello, Megan Waterman, Sandra Costilla, Jessica Taylor, and Valerie Mack. He is also expected to plead guilty to the 1996 killing of Karen Vergata.
  • The investigation, which spans decades, also used cellphone data, burner phone activity, and a 'blueprint' of his crimes found on a hard drive detailing meticulous planning and intent to murder.
  • Heuermann, a married father of two, lived in Massapequa Park, near Gilgo Beach, and was described by some as a quiet family man, while others recalled unsettling encounters and an arrogant professional demeanor.
