Convicted serial killer Rex Heuermann is undergoing intake processing at Green Haven Correctional Facility, according to the state Department of Corrections and Community Supervision.

Heuermann, whose crimes were carried out largely at his Massapequa home on Long Island, is now far removed in the Dutchess County facility following his sentencing Wednesday.

In April, he admitted to strangling eight women to death. His victims, Melissa Barthelemy, Megan Waterman, Amber Costello, Maureen Brainard-Barnes, Jessica Taylor, Sandra Costilla, Valerie Mack, and Karen Vergata, were found dismembered in discarded in different parts of Long Island, notoriously including Gilgo Beach.

Heuermann is serving three consecutive life sentences without the possibility of parole, plus an additional 100 years for the murders.

He was incarcerated at the Suffolk County Correctional Facility in Riverhead following his arrest in July 2023.

Green Haven is one of the state’s designated intake facilities, where newly sentenced individuals are evaluated before being assigned to another correctional facility.

Heuermann will be assigned to another facility based on an evaluation of his criminal history, security risk and other factors like medical, mental health and program needs.

The intake process begins in a reception center, where he will undergo medical and security assessments and an intake interview. After a security classification is determined, he'll be sent to a facility that matches his needs, security level, and program requirements.
