Very little is known about Carcani's early years, other than he was born in Albania on February 6, 1973, where he was also raised and was a domineering, narcissistic sociopath. He later became a member of RENEA, the country's special forces. In 2008, during his time at the job, he met and worked with Colin Bramwell, a sniper for the special forces in South Africa. Settling into the U.S. for his education when he was 23, Carcani became the vice-president for a private quasi-military security firm called Black Cross Private Security Services. Years ago, he met and married a woman named Maya, whom he severely physically abused. Finally, six weeks prior to the episode, Maya left Carcani with the help of an organization aiding battered women, without his own knowledge. Enraged upon finding out five weeks later, Carcani hired Bramwell to kill her while he was in Houston on a training seminar, so as to place suspicion off of him when Maya would turn up dead.
When Morgan and JJ go to his workplace to interrogate him in the episode, suspecting him of committing Bramwell's killings, he has just returned from his business trip. Spotting the two agents as they talk with a secretary, Carcani, realizing they are onto him, instantly flees and pulls out a handgun, firing several shots at them as he runs. Running out onto a street, he is hit by an oncoming bus, mortally wounding him. When Morgan demands Maya's location, he smiles tauntingly at him before dying. The BAU would later deduce that Bramwell is the killer and tracks him down, killing him before he can shoot Maya in her hotel room.
Since Carcani didn't kill anyone, the term "M.O." is misused. While he was married to Maya, he abused her physically. In order to avoid suspicion from police, Carcani hired Bramwell to carry out the killing of his ex-wife Maya. He later fired at Morgan and JJ with a semiautomatic pistol while attempting to escape.
No official profile of Carcani was made since the BAU's profile of the sniper was mostly focused on Bramwell. However, the BAU briefly judged that he may have been a narcissistic sociopath due to his willingness to die because of his confidence that Bramwell would kill Maya.
Carcani may have been based on Lee Harvey Oswald (who was referenced in the episode) - Both enrolled in their respective nations' armies, physically and sexually abused their wives (who were foreign women), and were linked to at least one sniper shooting in some way. They are also similar in appearance. Carcani's surname may also be a nod towards the Carcano rifle Oswald used.
Carcani is also similar to Allen Blackthorne, a scorned ex-husband whose life Sheila Bellush left him for another man due to domestic abuse. As a result, Blackthorne hired hitman Jose Del Toro to kill her out of revenge and to silence her.
Carcani also shares similarities to Kazuhito Komatsu - both are ex-partners of women who escaped abusive relationships, fearing for their life and took measures to protect themselves, which proved to be well-founded when the ex-partners hired hitmen to kill them, with whom the ex-partners were acquainted (in Carcani's case, the conspiracy was a failure).
