Corrections officials told The Post and Courier of Charleston that 22-year-old Quincy Howard is in disciplinary detention and can't make collect calls or have visitors after the contraband mobile phone was taken from his cell earlier this month.
Howard is serving a 30-year sentence for manslaughter from Marion County.
The newspaper reports Howard spent most of his time on Facebook last year playing the Mafia Wars and Cafe World games. But he occasionally gave status updates like: "RAILROADED BY THIS CROOKED A JUDICIAL SYSTEM IN SOUTH CAROLINA."
Howard's profile picture was a photo of him in his prison jumpsuit.
