NEW YORK — Accused serial killer Rex Heuermann and his estranged wife, Asa Ellerup, have reached a divorce settlement, some two years after he was arrested for a string of slayings known as the Gilgo Beach murders.

The divorce paperwork, signed by both Heuermann and Ellerup, was filed Thursday night in Suffolk County Supreme Court, but a judge still has to sign off before the split is legally official.

“After 29 years of marriage, Ms. Ellerup realizes it’s time to move on with her life and focus on a future for her and her children,” divorce attorney Robert Macedonio said in a statement to Newsday.

Heuermann, an architect who lived with his family in Massapequa Park on Long Island, was arrested on July 13, 2023, and charged in the murders of three of the so-called Gilgo Four women: Melissa Barthelemy, 24; Megan Waterman, 22; and Amber Lynn Costello, 27. And in January 2024, he was charged with killing the fourth, 42-year-old Maureen Brainard-Barnes.

Their remains were found within a quarter of a mile of each other near Gilgo Beach in December 2010 during a search sparked by the disappearance of Shannan Gilbert. Investigators in March and April 2011 uncovered the remains of another 10 people some nine miles away. Gilbert, who was a sex worker, like most of the victims, was not found until December 2011, more than a year after the search began. Authorities do not believe she was murdered and suspect her death was accidental.

Ellerup, who maintains she was unaware of her husband’s alleged double life, filed for divorce the same month of his arrest. Prosecutors have said she and her children were out of town when the killings unfolded.

Heuermann has since been charged with murdering another three women — Jessica Taylor, 20; Sandra Costilla, 28; and Valerie Mack, 24, whose remains were also found during the search on Long Island. He has pleaded not guilty in all seven cases.
