Gilgo Beach Murder Investigation Leads to New Search in Long Island

Heuermann, who lived in Massapequa Park and worked as an architect in Manhattan, was charged with the murders of sex workers Melissa Barthelemy, Amber Costello, and Megan Waterman.

Court documents revealed the victims “all had contact shortly before their disappearances with a person using a ‘burner’ cellphone (i.e., cellphones without an associated verified identity), and the cellphones of two of the four victims Brainard-Barnes and Barthelemy, were used by the killer after their death.”
