New York State Police say they’re investigating the Saturday death of an inmate who was housed at an upstate medium security prison – reports of which Gov. Kathy Hochul called “deeply troubling” on Monday.

The New York State Department of Corrections said the 22-year-old prisoner was housed at Mid-State Correctional Facility and died Saturday.

The death of 22-year-old Messiah Nantwi, an inmate at Mid-State Correctional Facility, has prompted an investigation by the Office of the NY AG and the NYSP.
