Accused Gilgo Beach serial killer Rex Heuermann and his estranged wife, Asa Ellerup, have reached a divorce settlement, according to court records.

       Ellerup filed for divorce shortly after Heuermann was arrested in July 2023.

       The terms of the divorce settlement, filed in Suffolk County Supreme Court Thursday night, are not public. A judge will review the settlement and must sign off on the divorce to make it final.

       Heuermann has pleaded not guilty to the murders of seven women whose remains were found discarded on Long Island between 1993 and 2011.

       Prosecutors with the Suffolk County District Attorney's Office have said Ellerup and the couple's children were out of town when the victims were killed.

       Heuermann is expected back in court Friday as his lawyers ask a judge to disqualify some of the DNA evidence pertaining to nuclear DNA results obtained from hairs recovered from six victims: Maureen Brainard Barnes, Megan Waterman, Amber Costello, Sandra Costilla, Jessica Taylor and Valerie Mack.

       The new DNA technique is whole genome sequencing of the DNA within a hair; scientists take all the fragments of DNA and assemble them on the human genome.

       Traditional DNA sequencing looks at 15 to 24 points of comparison, while whole genome sequencing looks at 100,000 or more points and the methodology yields only one possible donor.

       Heuermann's defense argued the new DNA methodology has never been tested in New York courts, but prosecutors have said the technique is already used in the medical community and is consistent with what the court system has allowed.
