Long Island officials to identify the identify Gilgo Beach serial killer victim Jane Doe No. 7: report

Suffolk County officials were expected Friday to release the identity of the Gilgo Beach victim known only for decades as Jane Doe No. 7, according to WABC-TV.

The news conference will come one day after Suffolk County Prosecutor Raymond Tierney told Newsday a second sex worker killed in an unsolved Gilgo Beach murder was bound with a unique belt bearing the initials HW or HM — and possibly holding another crucial piece of evidence.

He said hair removed from the buckle of the belt was still being tested.

The new revelations involve the killing of Maureen Brainard-Barnes, one of four women slain more than a decade ago in the remote suburban stretch. Long Islander Rex Heuermann was already charged in three of the killings and declared a a suspect in the fourth open investigation.

The district attorney’s office was planning a Friday morning news conference on the revelations.

Tierney told Newsday the initialed belt was one of three used to bind the 25-year-old victim, and police had previously said the belt was handled by the suspect in the killing.

Heuermann, 59, was arrested July 13 in Manhattan and charged with killing three sex workers — Megan Waterman, Melissa Barthelemy and Amber Lynn Costello — whose remains were found in 2010 near Gilgo Beach, in the same area where the fourth victim’s body was found.
