Justin Leu

Justin Leu is a delusional serial killer, stalker, and abductor who appeared in Season Ten of Criminal Minds.

Background
Justin's mother died when he and his brother Todd were children, causing their father Raymond to begin drinking and spiraling. He also abused both Justin and Todd, beating them whenever they received a grade less than an A in their schoolwork and also locking them in a shed for hours at a time. The two brothers bonded over their shared love of Inferno, the first part of Divine Comedy, a 14th-century epic poem, which detailed the journey of its protagonist Dante through Hell while guided by the Roman poet Virgil. Eventually, Todd, unable to take the abuse anymore, committed suicide by overdosing on pills, which led to Social Services taking Justin away from the custody of his father. In his adult life, he became an English teacher at a local high school and was extremely strict with his students. One of his students was Nathan Chow, who reminded him of Todd, which provoked a gradual psychotic reaction from him. The two struck a close friendship, with Nathan taking his classes twice, and when he graduated, Justin gave him a first-edition copy of Inferno. The two eventually decided to commit a series of Inferno-inspired killings when Nathan's life as a college student became miserable; they planned to end it in a double suicide based on the seventh circle, "Violence". Justin eventually began the killings after his father died and left the house to him.

Modus Operandi
Justin targeted men who were strict with their sons, which he observed while stalking them. Once the victims were alone in their cars on the road, he would bump into them and cause them to pull over, to which he would abduct them. Taking them to another location, he would then kill them in various ways, all of which represented the nine circles of Hell as described by Inferno.

 * Note: There were two other circles that haven't been attempted by Justin: the seventh circle, "Violence", and the ninth circle, "Treachery". Since both Justin and Nathan intended to commit suicide to represent the seventh circle, it is possible Justin had another target in mind for the ninth circle.
