The Correctional Association of New York is calling for expanded federal investigation of the state prison system, saying the death of a 30-year-old inmate after a confrontation with guards shows a complete overhaul is overdue.

The nonprofit advocacy group has state authority to inspect prisons. It says the Justice Department is already investigating Attica prison, following a severe beating there, and Clinton Correctional, where several prisoners reported beatings after two inmates escaped.

The group alleges abuse erupted this time at Fishkill Correctional in the Hudson Valley, where Samuel Harrell died from injuries there in April. The New York Times reported Tuesday his death was ruled a homicide.

The guards' union says it's reviewing the facts and violence against officers is at a record high.

The corrections department says it will respond appropriately to any findings of misconduct.
