Willie Kestler

"No. It wasn't crazy at all. After I heard that story, it all made sense. The voice in my head, the two mes...it was only one real me all the time: Russell Smith. That's who I am. That's who I'll always be."

Willie Kestler was a serial-turned-spree killer who copied the murders of Russell Smith in Perennials.

Background
During Kestler's birth at Hobson Regional Medical Center in Tuscaloosa, Alabama, which was two weeks after he was due, his mother Beverly required a C-section to get him out. Simultaneous to his birth, a serial killer named Russell Smith was rushed to the same hospital, mortally wounded from a shootout with police. Smith was placed next to Beverly in the emergency room. Just as Kestler was removed from Beverly's womb, Smith died from his wounds. When Kestler was five, Beverly died, leaving Kestler under the care of his grandfather Bill, who was extremely abusive towards Kestler and repeatedly accused him of having "the Devil" inside of him, and having the soul of a killer. A few years ago, right before Bill died, he told Kestler about everything that happened on the day of Kestler's birth. Intrigued, Kestler became an avid researcher of reincarnation, a religious concept in which the spirit of a body that has died travels into the body of a newborn. Kestler became convinced that he is the reincarnated form of Smith.

Three months prior to Perennials, in Chandler, Arizona, where Kestler had a residence, Kestler was injured in a one-car accident, and he claimed that someone cut his brake lines, wanting the Chandler police to figure out who did it. The police found no sign of foul play, but Kestler was obsessed with it. For weeks, Kestler kept showing up at the Chandler police station, saying that someone was after him, but was ignored. That was the trigger that got Kestler to travel to the Deep South and start killing people that he believed were reincarnated forms of the eight prostitutes that Smith killed, because he believed that one of Smith's victims had come back to get him. Kestler started by killing Charlie Clayton, a resident of a rundown neighborhood in Gulfport, Mississippi, and Nina "Floressa" Skinner, a member of a religious sect in Citronelle, Alabama. In both crime scenes, he leaves behind larvae and animal hair he brought, ensuring that the two would never come back in human form.

"My grandpa always said I had the Devil inside me...the soul of a killer..."

In the episode, Kestler recreates a scar prominent on Smith's jaw, and confronts a waitress named Brianna Wells later that day in Pensacola, Florida, calling her "Carol". Brianna isn't intimidated by Kestler and offers him free food that he requested. The following night, he ambushes Brianna in her car and kills her. Later, he arrives at a house, intending to kill one of the residents named Ted Sissler. Kestler knocks on the door, and it is answered by a college student named Kyle Owens, who is renting the house. When Kyle tries to close the door, Kestler swiftly knocks him out, and then holds Jane, Ted's wife, at gunpoint, asking her where Ted is. When she tells him Ted died from cancer, Kestler demands information about the date and location of his death. He then uses the information provided by Jane, finding a boy named Aidan Donahue and leaving the house without killing Jane or Kyle. Hours later, Kestler proceeds to abduct Aidan and take him to a downtown motel in Pensacola, where he explains his motivations to a terrified Aidan. By the time he is finished and intends to kill Aidan, the BAU and local police arrive, having deduced his location.

Recognizing only one possible escape route, Kestler releases Aidan and flees to Escambia Memorial Hospital, intending to kill himself in the presence of a newborn baby so then he could be reincarnated. He approaches a hospital clerk and asks where the baby rooms are. However, the clerk refuses to answer, as he needs to be a relative in order to have access. This prompts Kestler to shoot and kill the clerk in a fit of rage and in front of many witnesses. After killing a responding security guard, he makes his way around the hospital, searching for the baby rooms. He eventually finds them, forces a doctor out, and holds one of the babies. The BAU burst into the room and hold him at gunpoint, ordering him to put the baby down. Kestler obliges, but once he does, he then fires two shots, one of which hits Morgan, and the BAU shoot him in return. Kestler relishes in the fact that he will be reincarnated into the baby, but JJ carries the baby away to safety, and to his horror, he had dropped a box containing some of his larvae, one of which was, quite ironically, crawling on his arm. Hotch bitterly watches as Kestler dies, moaning, "No, no, no." It is revealed by the end of the episode that Morgan was protected by a bulletproof vest.

Modus Operandi
Kestler targeted people he believed were reincarnated forms of Smith's victims, finding them by determining their birth date and birth location, which would be identical to where the original victims died. He would then kill them by an emulation of Smith's M.O., with some differences. Kestler threatened them into compliance at gunpoint, made them bite down on a stick, and fatally hammer an icepick into the back of their neck. Unlike Smith, however, Kestler targeted ordinary citizens of both genders, operated in multiple states, and brought along a sample of animal hair and the larvae of flies native to the Southwestern United States. The motivation of the latter would be because that since reincarnation states that the spirit of a dead body travels into the closest newborn possible, Kestler wanted to ensure that the victims would never come back in human form, thus explaining the animal hair and larvae.

Profile
The unsub is operating out in the open with confidence, bordering on arrogance. He's been leaving a large amount of insects at the crime scenes. Normally, that would be a forensic countermeasure (artificially accelerating infestation of the corpse), or it could also be a symbolic way to degrade and humiliate the victims. Either way, these larvae are serving some other purpose for the unsub; it is like an obsession, and they are an essential component to his kills. He is slowly turning himself into the image of Russell Smith, even recently cutting himself on the jaw to replicate a similar scar on Smith. He may continue to alter his appearance: Smith had several distinctive scorpion tattoos, so the unsub might come to have them as well. The unsub seems to know exactly who he is looking for, but he refers to his victims by a different name, which means he is either delusional or he is using these victims as substitutes for someone. The larvae he is depositing at the crime scenes are indigenous to the Southwestern United States, so he would probably have a license plate from Arizona, Utah, or New Mexico. Smith preyed exclusively on prostitutes and infrequently, killing eight victims in a twenty-year period. However, this unsub is killing at a rate of one victim per day and he is targeting ordinary citizens.
