Myers was born sometime on 1974 as the youngest child of an abusive Julie Myers. On October 30, 1988, while he was fourteen, Myers was given a cochlear implant, for which Julie was paid $650 by the medical trial. At the time, it was a highly experimental and rather controversial procedure tested only on humans. By then, his entire childhood had been spent in isolation, most likely due to his deafness. As a result, he resorted to reading, which resulted in him gaining a high level of reading intelligence. After the surgery, Myers developed an interest in foreign languages due to his mother's New Orleans-based origins, but became enraged by a buzzing noise that was one of several side-effects of the surgery; another side-effect involved the left side of his face appearing sunken, with his left eye being unable to close on its own. On August 26, 2004, he snapped and killed Julie, sewing her mouth shut afterwards. Authorities didn't suspect him of Julie's murder, and he and his brothers were put in foster care. Both of Myers's older brothers, Mark and Greg, eventually went off the grid, their current statuses unknown.
Myers went on to kill two more women, with the last victim being murdered three months after Julie's murder. The BAU consulted on the case at the time, but were not directly involved as they were not invited by local police. Sometime in November, he was pulled over for a traffic violation, which was most likely intentional, as it would be revealed that he wanted to be caught. During the incident, police found no registration, no tags, and no means of identification, but a gun with a silencer (a reference to his nickname that went unnoticed) was found in his car. Because he had illegal possession of the gun, he was arrested and simply registered as a John Doe after there was no way of identifying him. He was then sentenced to life imprisonment without parole after he killed two other convicts in prison fights, never saying a word while doing so. During his time in solitary confinement as a result of the two murders of the inmates, he learned of a town well-known for its honey products from another inmate named Danny Tucker. The details of this town led to Myers believing it to be some sort of safe haven. He began a series of writings in prison and also developed an idea to flee to the town should he have the perfect chance.
Myers first appears in the episode, seen being strapped onto a stretcher by medics and prison officials as he convulses repeatedly due to a severe allergic reaction. He is wheeled onto an ambulance and is taken away. As the ambulance drives onto a lonely road, the prison guard on-board talks with the medic, telling him about Myers's homicidal tendencies, to which the medic asks him why they are saving his life. Just then, the driver spots a deer walking onto the road ahead and makes a sharp turn to avoid hitting it, but winds up driving the ambulance into a ditch and crashing into a tree. Everyone but Myers and the guard is killed in the crash; Myers revives from his state, breaks free from one of the handcuffs restraining him onto the stretcher, grabs the guard's key and Beretta 92FS handgun, and uses the former to unlock the other set of handcuffs. The guard regains consciousness, but Myers holds him at gunpoint. The guard convinces him to put down the gun, and Myers kindly helps him up, but when the guard attempts to go for his gun, Myers knocks him back down. He then fatally asphyxiates him before escaping with the guard's gun, several ambulance supplies, and the EMT's uniform. Later, in the coroner's office, Morgan and JJ are shown a note Myers left behind in the guard's mouth, which says, "Gazing through to the other side." As the investigation proceeds, Myers goes on to kill a gas station owner, leaving behind a note that said "Waiting on the taste of honey, smell of summer". Afterwards, he kills a male motorist, taking care of the latter's baby (and then stealing his car) after killing him.
The BAU soon realizes that Myers's messages are clues to where he intends to go. Meanwhile, he starts hallucinating about his abuse at the hands of Julie after finding the secluded spot in Sweetwater Tucker had talked to him about, only to find it mostly under reconstruction. Myers promptly becomes scared by the loud buzzing noise that is brought by the heavy machinery sounds. The BAU later find out that Danny Tucker might be in serious danger, as Myers would become enraged at discovering his supposed safe haven being under construction, and leave for his house, but Myers reaches him first, holding his wife and daughter hostage and knocking him out when he tries to fight back. He then puts him on a chair and attempts to sew his mouth, but Danny regains consciousness and Myers again asphyxiates him to the point of unconsciousness. Believing he is dead, he resumes his assault, but is cut short when the BAU burst into the house and hold him at gunpoint. Blake, the team's newest member, tries to reason with Myers, communicating with him through sign-language. Myers argues that he doesn't want to return to prison, but Blake tells him that there is no other way. In defeat, Myers stands up, backs away from Tucker and up against a wall, and commits suicide by shooting himself under the chin with the guard's gun.
As the unsub whose M.O. was the first to be emulated by John Curtis onscreen, Myers would go on to be mentioned or referenced throughout the rest of the season. At the end of The Apprenticeship, Hotch was informed via cell phone call that a body with his mouth sewn shut was found in Dallas. He and Rossi briefly converse on this, stating that it was definitely a copycat, as Myers is already dead. At the end of Magnificent Light, a photo of the Myers-based victim is seen in the copycat's room. Myers was briefly mentioned again in Perennials by Hotch. At the end of Broken, the copycat can be seen viewing the photos of his victims, including that of the Myers-based victim; such photos would reappear in The Gathering and Brothers Hotchner. Myers was mentioned frequently by the BAU in Carbon Copy. He was then mentioned in the season finale episode The Replicator, where it is revealed that the Myers-based victim was the copycat's second victim, not the first. Two years later, Myers was mentioned once again in Angels when Hotch stated that a Texas Sheriff had examined their handling of the Silencer case, which inspired him to summon the rest of the team to investigate a series of religious murders.
Before his incarceration, Myers targeted brunette, Caucasian working-class mothers in their late 40s, all of whom resembled his mother Julie, his first victim. He attacked them at night and beat them to death. His signature was torturing his victims by sewing their mouths shut with thread, using a unique double-knot ligature. He then left their bodies in ditches. In prison, he beat two inmates to death with his bare fists during fights, but he didn't sew their mouths shut since he didn't have access to threading.
After his jailbreak, his M.O. evolved; he targeted men out of necessity, left messages in the mouths of two of the victims before sewing them shut, asphyxiated them by pressing his right arm against their necks while his left hand was against the back of their heads, and left their bodies where he killed them. These messages were written on white sheets protected inside plastic bags, and were meant as clues to find out where his last crime was going to be committed. After killing the victims, he would steal items from their bodies, such as a weapon and a quick disguise.
The unsub is a white male who is between the ages of 35 and 45, about 6'0" to 6'2" in height, and weighing 180-200 pounds. It can't be predicted where he is going, or what his current state of mind is, but his seemingly random actions will betray his intentions eventually. It is also unknown as to why he leaves messages in the mouths of his latest victims. At the gas station, he could have stolen money in the cash register, but he did not, which means he isn't planning a long road trip, but he is logical enough to be aware of survival skills. Sewing the mouths of his victims is a compulsion over which he has no control, which could mean he feels silenced by having a speech impediment, which makes him embarrassed to talk, and therefore caused him to be a target of relentless bullying and torment because of it. His first three victims indicate that a woman, likely a mother figure, is to blame for his rage. Chances are that she was abusive and convinced him that whatever he would say did not matter.
References to IPA, the International Phonetic Alphabet, in his personal writings indicates that he is able to hear and talk but chooses not to. His usage of multiple languages highlights a desire to communicate, and he also seems to be proficient in sign language. Additionally, he is incredibly well-read, which means he most likely grew up in isolation, with literature being his only escape from his cruel reality. His own writings do not seem as profound, and despite his astounding reading comprehension, he most likely did not have an extended, or at the very least, outstanding education. Every aspect of his psychosis says that the spoken word has value to him, but it also greatly angers him. If he was yelled at or made to feel stupid by a maternal figure, he held onto his anger until he snapped. He can possibly snap like this while on an important mission. It is unknown if his target includes a person of some type or a particular location, but his target is definitely close by.
His prison photo shows that the left side of his face is sagging; a facial deformity such as that combined with a possible speech impediment could cause him to suffer from low-self esteem. Being imprisoned for years figuratively took away his voice, but not his rage. He might have started the fights he had in prison so he would be punished, and it could be his way of looking for silence.
He did not leave a message in the mouth of his latest victim, which indicates that caring for the victim's baby son is his message. He may relate to the child and is obsessed with the nurture he did not get, or he simply just wanted for him to be quiet. He is not saying he has boundaries, because he is too mentally unstable for that. He left most of his medical equipment at the crime scene, which is usually an unsub's way of surrendering, yet he still has the prison guard's gun, an indication that he is not giving up. His original killings and M.O. was his message ("I hated the women I killed"), and he is most likely not targeting women anymore because he has already killed the person who was the subject of his blame.
Myers seems similar to serial killer Henry Lee Lucas, a.k.a. "The Confession Killer". Both were abused by their mothers (who were their first victims), were similar in appearance (especially with their left eyes), killed three women (all three of Lucas's confirmed victims were women, while Myers killed three women prior to his arrest and incarceration). In addition, Lucas killed most of his confirmed and alleged victims in Texas (the same state where Myers committed all of his murders).
Myers is also partially similar to Seisaku Nakamura. Both were serial killers who were both deaf and highly intelligent, and also killed members of their family (in Myers' case, he killed his mother; in Nakamura's case, he killed his brother).

- Myers's arrest for illegally owning a silencer seems to be based on a November 1992 arrest that was placed upon serial killer Thomas Dillon, who also illegally possessed a silencer.
- As the first unsub whose M.O. was first seen being copied by the Replicator, Myers currently holds the most mentions and references for a single one-time male unsub, with a total of nine.
- Myers leaving messages in the mouths of two of his victims seems to be reminiscent to how Season Two serial killer Sarah Danlin left a message in the mouth of the last victim she killed.
- Myers is similar to Season Seven criminal Thomas Yates, a.k.a. "The Womb Raider". Both were serial killers who were abused by female parental figures (Myers was abused by his mother, while Yates was abused by his grandmother), killed female victims who were surrogates for their abusers, were previously incarcerated for crimes they committed (Myers was incarcerated for illegally possessing a silencer; Yates was incarcerated for killing a boy that bullied him), had signatures that involved torturing their victims (Myers tortured his victims by sewing their mouths shut; Yates tortured his victims through starvation), killed their first victim out of revenge, were based on real-life serial killer Henry Lee Lucas, and were given names by the media for their crimes.
- Myers is also partially similar to Season Seven criminal Rodney Garrett. Both targeted women (although Myers targeted them during the first phase of his killings), killed two inmates while incarcerated, and later had someone commit at least one copycat murder after their deaths.
- Jarrod Bailey, the actor who played Myers as a teenager, also played Simon in the Season Two episode The Boogeyman.
