Gilgo Beach Serial Killer Suspect Rex Heuermann Now Charged With Murdering Fourth Woman: Officials

Gilgo Beach serial killer suspect Rex Heuermann has officially been charged with murdering a fourth woman who disappeared in 2007 while working as an escort, according to authorities.

Heuermann, 59, already had been charged with the murders of three of the so-called Gilgo 4 — the women found dead on Long Island’s Gilgo Beach in December 2010 — and he was also the prime suspect in the death of the fourth, as Front Page Detectives previously reported.

Last July, Heuermann was accused of the murders of Melissa Barthelemy, 24, Amber Costello, 27, and Megan Waterman, 22, and on Jan. 16, prosecutors announced he faces a second-degree murder in connection with the death of 25-year-old Maureen Brainard-Barnes, ABC News reported.

Authorities said they linked Heuermann to Brainard-Barnes' death through DNA and other evidence. Her body and the remains of the three other victims were found in a desolate spot along the ocean near Gilgo Beach.

As Front Page Detectives previously reported, officials in Las Vegas are investigating five unsolved murders that could also be linked to Heuermann.

Heuermann had previously pleaded not guilty to the three counts of murder he faces.

He remained silent during Tuesday's brief court appearance, NBC News reported. His estranged wife, Asa Ellerup, was in attendance.

His next court hearing is scheduled for Feb. 6.
