Two inmates charged with attacking another inmate at the Albion State Correctional Institution are facing attempted homicide charges.

Antwan Sheppard, 30, and Shane Jones-Coleman, 27, are now facing charges of attempted criminal homicide, aggravated assault, and assault by a prisoner.

Both men were formally arraigned by video on Tuesday, in front of District Judge Christopher McKendrick.

On September 1, 2016, police say the two men, along with 32-year-old Jordan Spoonhour, attacked another inmate, identified as Rosco Brown.

During the attack, Brown was knocked unconscious.

Investigators say the three men then repeatedly punched, kicked, and jumped on Brown and did not stop the beating until prison staff members broke it up.

Brown suffered from bruising to his face and head, and a concussion.

Meanwhile, during another attack at the same time, police have charged 29-year-old Kareem Savage with criminal homicide.

Police say Savage punched fellow inmate Anthony Wilson in the head, which caused him to fall.

According to investigators, Savage then kicked and stomped on Wilson's head, as he laid defenseless on the floor.

Wilson died in the hospital about three months later.

Both Sheppard and Jones-Coleman are scheduled to be back in court on December 4, for their preliminary hearings.
