"You heard me. And you'd better keep your damn mouth shut."
Jones was a serial rapist who was later caught and tried for his crimes. He was sentenced to twenty years at the Reagan Federal Penitentiary. At the penitentiary, he gained the trust of Dale Shavers, the head of security, after giving him reliable information from time to time. When Shavers and several other prison guards set up a fight club and used prisoners as their fighters, Jones volunteered to help round up potential fighters. He also became Shavers' spy and informant. As a result of his help, Jones achieved 'privileged' status, giving him more efficient privileges than that of other inmates. Recently, he got a new cellmate, Devon White, who became one of the unwilling participants in the fight club. Jones presumably raped Devon repeatedly to keep him quiet, as Devon's infirmary records indicated signs of sexual assault during some of his visits.
When several people connected to Shavers and the fight club are murdered by Patrick Butler, the BAU are called to investigate. As a result, Jones confronts Sam Pritchett, one of the inmates involved in the fight club, and threatens him, telling him to keep his mouth shut. Later on, he takes a shower, but is ambushed by Butler, who rapes him and then kills him by boiling him alive in scalding, spraying water from the shower.
Because Jones wasn't primarily focused on in the episode, absolutely nothing is known about how Jones raped his victims.
No official profile of Jones was made by the BAU.
- Numerous unnamed victims (all raped prior to his arrest and incarceration)
- Devon White (presumably raped repeatedly)
