Melaine T. Liverpool, 33, was found dead around 3:44 a.m., Wednesday, May 8, at the facility located at 247 Harris Road in Bedford, said Trooper AJ Hicks.
Liverpool was sentenced a month ago to 20 years to life in prison for pushing a Queens woman in front of a train at the Times Square Station more than two years ago.
Diagnosed as a schizophrenic. Liverpool admitted to officials to fatally shoving 49-year-old Connie Watton of Queens in front of a southbound No. 1 train on Nov. 7, 2016.
Watton was a longtime housekeeper for billionaire Blackstone Group CEO Stephen Schwarzman.
Liverpool had just been released from the Bellevue Hospital psych ward for lying about pushing a woman in front of a train when the crime took place.
The official cause of death will be determined by the Westchester County Medical Examiner’s Office, state police said.
The investigation remains ongoing.
