A New York grand jury charged two prison guards with second-degree murder and eight others with related crimes, in the beating death of an inmate last month at a prison in Central New York, according to court papers unsealed on Wednesday.

Ten New York prison guards were charged Wednesday in connection with the fatal beating of a 22-year-old inmate last month — including two charged with murder. It’s the second time a group of correctional officers in the state was indicted for a death behind bars this year.
