Architect Rex Heuermann was arrested in Manhattan Thursday night. A suspect has been arrested in connection with three of the 10 victims linked to the Gilgo Beach, New York , murders, authorities said. Barthelemy disappeared in July , Waterman disappeared in June and Costello was last seen in September The three women were between 22 and 27 years old and all worked as sex workers, court records said. Shortly before each woman vanished, she had contact with a person using a "burner" cellphone without a verified identity, according to court records.
The cellphones of two victims were used by the killer after their deaths, according to records. On five occasions in the summer of , someone in midtown Manhattan -- which is where Heuermann's office is located -- used Barthelemy's phone to make "taunting phone calls to Ms.
Barthelemy's family members," court documents said. Some of the calls "resulted in a conversation between the caller, who was a male, and a relative of Melissa Barthelemy, in which the male caller admitted killing and sexually assaulting Ms.
Barthelemy," documents said. According to court documents, records established that Heuermann's wife was out of town when Barthelemy, Waterman and Costello disappeared. A fourth victim, Maureen Brainard-Barnes, who vanished in July , was also tied to the three women.
While Heuermann is not charged in the death of Brainard-Barnes, the court document said he is the "prime suspect in her death. Male hair was recovered from the burlap used to wrap Waterman's body, and that DNA was found to be a match to leftover pizza crust Heuermann threw into a Manhattan garbage can in January , according to court documents.
