Convicted Gilgo Beach serial killer Rex Heuermann is expected to be sentenced on Wednesday, with the possibility that he could address the court before receiving multiple life sentences for a series of murders that terrorized Long Island for nearly two decades.

At a court hearing in April, Heuermann pleaded guilty to the murders of seven women: Melissa Barthelemy, Megan Waterman, Maureen Brainard-Barnes, Amber Lynn Costello, Jessica Taylor, Valerie Mack and Sandra Costilla.

He also admitted responsibility for the killing of Karen Vergata, although he was never formally charged in connection with her death.

Family members of the victims are expected to deliver impact statements during Wednesday’s sentencing hearing, offering them an opportunity to address Heuermann directly before the sentence is imposed.

Under the plea agreement reached in April, Heuermann agreed to serve three consecutive life sentences, followed by four additional consecutive terms of 25 years to life, according to prosecutors.

Authorities said the New York architect preyed on sex workers over a 17-year period, strangling his victims and disposing of their bodies in areas near Gilgo Beach on Long Island.

Announcing the plea agreement earlier this year, Suffolk County District Attorney Ray Tierney described Heuermann as a man who concealed a violent double life.

“He walked among us, play acting as a normal, suburban dad, when in reality, all along, he was obsessively targeting innocent women for death,” Tierney said.

The sentencing marks a major milestone in one of the most notorious serial murder cases in New York history, bringing a measure of closure to families who have waited years for justice.
