Laurinburg, N.C. — A state prison inmate faces additional charges in the fatal stabbing of a fellow prisoner, and a second inmate has been charged in the case, the Department of Correction said Tuesday.

After the State Bureau of Investigation and the Scotland County Sheriff's Office looked into the Feb. 5 killing of Gary N. Bell, 41, inside the Scotland Correctional Institution, investigators charged Edward Wiley, 25, with conspiracy to commit murder. He already had been charged with first-degree murder.

They also charged Jodie Steele, 26, with conspiracy to commit murder and with being an accessory after the fact. He was convicted in 2006 in Harnett County of involuntary manslaughter and robbery and sentenced to four years and seven months.

Bell died of multiple stab wounds to the chest. Correction Department records show he was serving a 12-year sentence after being convicted in Sampson County as a habitual felon in 2002.

Wiley was serving a 15- to 19-year sentence for statutory rape.
