James Thomas

James Thomas was a serial killer (and briefly a spree killer) who appeared in Compromising Positions.

Background
James and his wife, Mary-Ann, were regular swingers. He would usually select husbands for Mary-Ann, let them have sex with her and then step in himself. He worked as a freelancing locksmith. In 2009, he suffered from a condition called prostatic hyperdisplacia. He went in for a routine surgery which went bad, forcing the doctors to remove the whole prostate, rendering him impotent in the process. He and Mary-Ann still kept attending swingers' parties, even though he couldn't take part in the activities. One day, his wife became pregnant with another man. This loss of control drove James to become a serial killer, starting with the man who impregnated her.

Season Six
In the beginning of the episode, James has just completed his ritual, forcing a husband and wife to have sex in a car and killing them. This leads to the BAU being called in. During his next murder, the husband puts up too much of a fight, completely destroying the fantasy. After long struggle, James is able to reach his gun and shoot the husband to death. He then turns to the wife, forcing her to say she wants him. In an attempt to survive, she plays along, even taking off her robe, only to be shot as well. James later attends another swingers' party. The host lets him in, knowing him, but asks why Mary-Ann isn't with him. James claims she is on her way and is trusted. On the dance floor, he sees a dancing couple get approached by another man, which is his usual fantasy. As the trio make out in a couch, James watches them and grows increasingly frustrated until he snaps, pulls out a pair of handguns, shoots them and anyone else in sight. He then begins moving around the house, shooting any men he can find, and escapes.

When investigating the scene of the mass shooting, Reid and Rossi discovered that James unlocked a door by succesfully picking it rather than shooting it open even though it was a deadbolt lock, an act which only a professional could do. Garcia narrows down the list of potential suspects to James. The BAU and local police raid his home and find Mary-Ann, who, surprisingly, is pregnant. They question her, trying to learn who the father is, but she keeps claiming that James is the father, even though his impotence predates her impregnation and there is no record of her being inseminated in some other way. Reid shows her crime scene photos of men who have been killed by the same type of weapon that James uses. When she sees one of them, she breaks and admits that he is the father, not James. They ask her about their prior sexual habits, since James is most likely revisiting old patterns. She tells them that they used to do pickup roleplays at a local bar. The BAU go to the bar they would go to and find James there. Since he is highly unstable and there will be a lot of collateral damage if he is provoked, Emily goes in, pretending to be a fellow swinger who met him years earlier. She begins chatting him up in order to distract him while the others approach him. Realizing that she is lying when she gets his pattern wrong, James grabs a gun within his jacket. While SWAT enters, Emily reaches into her handbag and shoots James through it. As he lies dying, he asks Emily to tell Mary-Ann that he loves her.

Modus Operandi
James targeted couples the husbands of which he met in the line of work. The husbands were always alpha males. He would bind them with handcuffs, make the men ingest Viagra and force them to have sex in front of him, even setting up a romantic scenery with candles and soft music (depending on what the scene of the act permitted) and make the husbands wear a condom to make things as comfortable as possible. Once the couple were done, he would kill the husbands by shooting them with a suppressed 9 mm handgun and stab the wives to death.

Profile
The UnSub is an emasculated alpha male with a near obsessive-compulsive need for control. The repeated details of the murders show that his ritual is essential to him. He is a troilist, someone who gets off on staging scenes and participating in them. He almost definetely has some woman in his life, most likely a wife, as he wouldn't be allowed to enter a swingers' party alone. The fact that his fantasy is two men with one woman suggests that his fantasy is sharing his wife with an unmarried man and then steping in to prove his masculinity. He practised this fantasy in his ordinary life, but when he became impotent for some reason, he could no longer complete it and began killing to gain release. Because of his last murder, which went very wrong and disrupted his ritual, he will begin a process called "decompensating". This means that, since his pattern has failed, it will affect his future ones. And since his first loss of control was most likely his wife, he will start pursuing a new pattern based on her or women like her. At the end of a decompensation, the UnSub will go into a temporary psychotic break and start revisiting old patterns to see if they still work. When he finds that they don't he will be compelled to destroy them and anyone involved in them.
