Mississippi corrections officials have asked National Institute of Corrections experts to visit the state prison at Parchman to review its gang interdiction program.
Corrections Commissioner Chris Epps Wednesday that he contacted the NIC after the killing of Earnest Lee Hargon by an inmate/gang member at the prison. Hargon died Tuesday of stab wounds.
Hargon was sentenced to death for killing three family members in 2004.
Epps said corrections officials are trying to determine how the assailant, identified as inmate Jessie Wilson, got the homemade knife used to kill Hargon in Parchman's maximum security unit, called Unit 32.
Epps said Wilson had ties to the Latin Kings gang. Epps said Hargon had no known gang ties.
Epps said some changes are being made to the department's screening process to root out gang influence among corrections officers.
