Patrick Butler

"They gonna figure it out. And they gonna find you, you son of a bitch."

Patrick Butler was a serial killer who murdered several people inside a prison in Lockdown.

Background
Butler was a bank robber who robbed five banks in three different states using a toy gun. He was arrested and initially sentenced to five years in Reagan Federal Penitentiary, but the sentence was bumped up to twenty years after he killed another inmate. He was one of many inmates forced by Captain Dale Shavers, the head of security, and several other prison guards to participate in a "fight club". One night, Butler and a new inmate, Devon White, were pit against each other in a fight, during which Shavers handed him his baton. Butler used it to beat Devon, although the blows proved to be unintentionally fatal. In the aftermath, some of the guards disposed of Devon's body in a furnace, while Butler was left traumatized by the ordeal. Eventually, he, along with several other inmates, began a series of killings, targeting people connected to Devon's death and Shavers and his gang. They were assisted by a prison guard, Tom Polinsky, who had stumbled upon the fight club activities by accident and was forced to stay silent about it, though was ambivalent towards Shavers' intentions.

Lockdown
After the group killed two prison guards and an inmate involved with Shavers, Butler's cell is searched by Shavers and two of his accomplices. They find shivs and socks in a hidden box, and Shavers orders Butler to be taken to solitary confinement (which is located at the hallway where Devon died). There, he is confronted by Shavers, who demands to know who else is involved. Butler assaults him, but is quickly overpowered by him. When Shavers demands information, Butler mocks him and tells him the BAU (who are investigating the deaths) will find out about the fight club eventually. Shavers tries hitting him with his baton, but Butler assaults him again. He is overpowered again and bludgeoned to death.

Modus Operandi
Butler and his accomplices targeted people connected to Shavers, his gang, and the fight club. Officers Rudy Hightower and Keith Rivers were stabbed in the neck with shivs, while Randall Jefferson Jones was raped (as a reference to his previous crimes as a serial rapist) and then drowned in scalding water. Signatures for all three murders were that socks were stuffed down the victims' mouths prior to their deaths, and that seven of their fingers would be completely broken (as a reference to cell 34, a solitary confinement cell where Devon died).
