Arthur Mitchell is a middle-aged serial killer who has been active for three decades without being noticed. Agent Frank Lundy, the FBI's lead investigator of his crimes, has dubbed him "The Trinity Killer" because it was believed that he killed in threes. However it has since come to light that he in actuality kills four victims every cycle. His M.O. is to kill a series of four people in a very specific fashion. The first victim is a young boy, usually around the age of 10, whom he buries alive in wet concrete. The second victim is a young, single female, whom he forces into a bathtub with him. He then severs her femoral artery and watches them bleed to death in a mirror. His third victim is a slightly older woman, married with two children. He brings her to the top of a building and forces her to jump to her death. The fourth and final kill in his pattern is an older male, also a parent of two children, whom he bludgeons with a hammer. He's immaculate, always careful never to leave any trace of his presence at the scenes of his crimes. Through his killings, he's recreating the traumatic deaths of his own family members. He performs this cycle roughly twice every year.
Arthur Mitchell has killed roughly around 240 people over the past 30 years.

Handsome with a good-natured grin, Sam is a former Navy Seal, Military Intel Operative, and all-around Cold Warrior. In his prime he was point man on an array of armed conflicts the world over. He worked with Michael many times during those heady days. When Michael reconnects with him in Miami, Sam has embraced his post-espionage days by letting loose. Once, he loved the threadbare world of secret surveillance in the communist bloc, or forward recon in the touch-and-go Middle East.
Now, he has moved on to mojitos, Sugar Mommas and bikini watching in the bars and on the sands of South Beach. He's reliable and consistent, in the way that you can count on a former spy to dig up solid intel and execute missions with stealthy aplomb. Despite his predilection for rich divorcées and cocktails, he is an asset to Michael, even when he becomes an informant for the FBI. Though the Feds have Sam keeping an eye on Michael, he needs Sam's friendship, partnership, and expertise, now more than ever.
