A city correction officer from Staten Island who had teenage inmates serve as his jailhouse enforcers will now head back to prison as a resident, according to the Staten Island Advance.

Khalid Nelson, 37, of West Brighton, pleaded guilty Friday in Bronx state Supreme Court to a felony count of attempted second-degree assault.

Authorities say Nelson and two other corrections officers allowed and encouraged a system of intimidation at a housing unit in the Robert N. Davoren Center, in which a dozen of the stronger inmates ran the place. Authorities say it led to the death of one teenager.

Nelson and fellow correction officer Michael (Mack) McKie, 33, of Brooklyn, recruited inmates to manage the other juveniles. These recruits, in turn, could force other inmates to give them a percentage of their commissary accounts and phone privileges, and sometimes even give up their shoes and clothes.

When beatings occurred, McKie and Nelson would usually determine where and when they would happen, and let their “managers” use locked, secluded areas for them. Afterward, the officers would file false reports about the assaults, and force victims to make false statements, authorities said.

On Oct. 18, 2008, 18-year-old Christopher Robinson was beaten to death by other inmates because he would not go along with the extortion scheme, according to investigators.

Nelson will be sentenced Jan. 17 to a year behind bars, while McKie will receive two years, the commissioner of the city Department of Investigation said. The third defendant, Officer Denise (Mama A) Albright of Manhattan, has her case still pending.
