Two corrections officers were charged with second-degree murder and eight others with related offenses on Wednesday in the killing of a man who inmates said was savagely beaten to death by guards last month at a prison in central New York.

The man, 22-year-old Messiah Nantwi, died March 1 after he was beaten at the Mid-State Correctional Facility in Marcy, N.Y., near Utica. Mr. Nantwi, other inmates said, was bloodied, swollen and unrecognizable after the beating.

An 11-count grand jury indictment was unsealed on Wednesday charging two officers, Jonah Levi and Caleb Blair, with Mr. Nantwi’s murder. They and three other officers were charged with manslaughter in the first degree and gang assault, and two more were charged with second-degree manslaughter. Eight of the officers were charged with trying to cover up the attack.

The charges were announced by William J. Fitzpatrick, the Onondaga County district attorney, who was appointed special prosecutor in the case.

It is the second time in four months that New York State corrections officers have faced criminal charges in the death of an inmate. The other inmate, Robert Brooks, 43, was fatally beaten by guards in December at the Marcy Correctional Facility, directly across the road from where Mr. Nantwi was beaten.
