Michael Kosina's previous accomplices
The accomplices of then-serial rapist Michael Kosina in northern Louisiana, who both disappeared after being killed by Michael himself following a series of rapes in the area. The police pinned the crimes on them as a result until Michael's death.
A serial killer in North Dakota known as "The Redmond Ripper", Charles Beauchamp is the father of FBI cadet
Ashley Seaver. When she was a child, he killed 25 women over the course of 10 years. His nickname suggests their deaths were very brutal and bloody. He was extremely protective of his daughter and was terrified of letting her out of the house because he knew there were more men like him outside. He tried very hard to be a good father and would give her all the toys she wanted, though he refused to have any pets in the house because he knew he couldn't control his homicidal urges around them.
In the end, he was arrested by Rossi and Hotch. He would later say it was the best day of his life as it meant he no longer had to hide and wouldn't hurt anyone else. Because of that statement, it is possible that his killings, or at least a portion of it, were acted out of compulsion. He is currently in prison, since North Dakota doesn't have capital punishment, and is very likely serving a life sentence with no possibility of parole. He sometimes writes to Seaver, though she never reads his letters.
Hollis Walker, Sr.
The father of serial killer Hollis Walker, the senior Walker was an expert on indigenous African religions who was highly abusive towards his son, to the point where he didn't bring him back home from boarding school even after his wife and the younger Hollis' mom committed suicide, leaving Hollis to stay at school even during vacations and school breaks. After the younger Walker also became a professor of indigenous African religions as an adult, Hollis Sr. wrote a negative review of a book he wrote, which became a catalyst in Hollis Jr.'s murders.

The alcoholic father of sociopathic spree killer Raymond Donovan. When Ray was seven, Paul molested his son, presumably while he was drunk, and Ray was traumatized ever since. An adult Ray tracked Paul down in Idaho during his killing spree with his wife Sydney Manning, held him and his own wife hostage, and played a game of Russian Roulette with him in order to get him to confess to the molestation and make amends. When Paul repeatedly and vehemently refused, denying the molestation ever occurred, an impatient Sydney shot him through the forehead, killing him instantly.
The father of psychopathic spree killer Sydney Manning, who owned a gas station. He was a pedophile who repeatedly molested his daughter as a child, sometimes while at work. The molestation shaped Sydney's psychopathic tendencies as a result. When an unknown event placed Sydney in foster care in Billings, Montana, Gary moved on and married another woman named Karen, having a daughter named Heather with her.
For some unknown reason, he decided to change his pedophilic ways and became a devoutly religious man, never sexually abusing Heather even once. An adult Sydney tracked him down in Spokane, Washington, during her killing spree with her husband Ray, held him and Heather hostage, and beat him despite his pleas that he had changed and that he never hurt Heather. An unconvinced Ray took him to a back room and fatally shot him.
A resident of an apartment complex in which the unsub claimed another victim, Hadley shot a cleaning man in the genitals when he learned that his wife was sleeping with him. It is unknown if the victim survived.

He was later arrested and incarcerated for his crimes. Waters was also responsible for the death of a police officer named Scott Jarand, who was killed instantly in another collision, which made headlines.

A sex offender convicted of flashing a woman.
A coworker of Morgan's cousin, Cindi, who began stalking her in 2004. Though they only went on one date and shared one goodnight kiss, he started calling her constantly and sending her gifts that she returned. Ultimately, his stalking became so severe that she fled the state and went to Charleston. She did so on Morgan's advice, as he knew Hitchens was a power-assertive stalker and that it would most likely end badly if the stalking continued.
Two weeks after Cindi disappeared, Hitchens was shot and killed by Malcolm Ford, a man also stalking Cindi who made it look like a suicide. At the time, the police figured Hitchens had killed Cindi, though there was no body. However, this was eventually proven to be false on the episode's follow-up, The Company.
