A Hybrid Killer (so named in this wiki) is a person who fits the descriptions of two or more separate pathology types, making it difficult to officially classify them in either type.

Criminal MindsEdit

• Edward Hill ("Poison"):
  • Mass murderer: Edward poisoned numerous people connected to the pharmaceutical company he once worked at with LSD, in an attempt to kill them.
  • Unclassified killer: Only two people were killed as a result of the attacks.
• Vincent Stiles ("Ashes and Dust"):
  • Serial arsonist: Stiles set buildings ablaze and has a sheer, rather compulsive desire to see the resulting destructive effects.
  • Serial killer: Stiles specifically chose aforementioned families; the fathers are workers of companies accused of constructing LUSTs (Leaking Underground Storage Tanks). He would later devolve from being a family annihilator, killing a random businessman and attempting to kill his former employer Evan Abby.
• Armando Salinas ("Catching Out"):
  • Spree killer: Armando killed his victims between short cooling-off periods, and his victims also varied in many different prospects, such as age, gender, and later race.
  • Serial killer: However, unlike most spree killers, Armando maintained his M.O. of bludgeoning with an incidental object.
• Norman Hill ("Normal"):
  • Spree killer: Norman killed his victims between rather short cooling-off periods.
  • Serial killer: There was one occasion where Norman tried to go through a long cooling-off period; though he succeeded, it proved rather difficult for him.
• George Foyet ("Omnivore", "...And Back", "Nameless, Faceless", and "100"):
  • Serial killer: Foyet killed his first twenty victims between long cooling-off periods, like any serial killer depicted on the show. After committing a massacre as detailed below, Foyet spent the duration between "Omnivore" and "...And Back" tracking down Hotch, without presumably killing anyone. After torturing Hotch in "Nameless, Faceless", Foyet went through another long cooling-off period between said episode and "100", before returning to make his final stand against the BAU.
  • Spree killer: In "Omnivore", Foyet started a night-long killing rampage that resulted in the deaths of everyone aboard a transit bus, including the driver, and a Boston policeman. In "100", he nearly became a spree killer again, killing Sam Kassmeyer and Haley Brooks-Hotchner in one day.
• Tommy Wheeler ("House on Fire"):
  • Serial arsonist: Like Stiles, Tommy set buildings on fire.
  • Mass murderer: However, unlike a typical serial arsonist, Tommy would ensure that as many people as possible died in his fires by sabotaging the water lines and locking all exits from outside.
• Kaman Scott ("Devil's Night"):
  • Serial killer: Kaman specifically chose the people who he believed wronged him in some way to be killed by him.
  • Serial arsonist: Kaman killed his victims by setting them on fire. Though his profile didn't officially categorize him as an arsonist, he used fire as a murder weapon. Stiles was described the same way.
• Ben Foster ("With Friends Like These..."):
  • Spree killer: Ben killed one victim nightly, which is a somewhat short cooling-off period.
  • Unclassified arsonist: Ben killed his first three victims with a fire.
• Dylan Kohler ("Divining Rod"):
  • Serial killer: Kohler targeted specific victims and planned out his attacks beforehand.
  • Spree killer: However, he attacked several people within a roughly two-day span.

Real WorldEdit

• Anders Behring Breivik:
  • Terrorist: Breivik's killing spree is described as acts of Christian terrorism.
  • Spree killer: Breivik killed 8 in the car bombing in Oslo, then shot to death 69 students on the island of Utøya.
• Carl Panzram:
  • Serial killer: Panzram killed most of his victims between long cooling-off periods, like any real-life serial killer would.
  • Serial arsonist: He admitted to also setting numerous fires.
  • Spree killer: Over the course of three weeks, Panzram killed a total of ten sailors by drugging them, raping and murdering them, and throwing them overboard a boat, making for short cooling-off periods.
• Robert James Sartin:
  • Spree killer: Sartin fired indiscriminately at fifteen Monkseaton civilians with his father's double-barreled shotgun he stole before being arrested by an unarmed policeman.
  • Unclassified killer: Only one person was killed in the shooting, while the rest were wounded.
• Anatoly Onoprienko, the Beast of Ukraine:
  • Spree killer: Onoprienko killed entire families or groups of people, as well as potential bystanders, and his last 43 victims were killed in the last six months of his murder spree.
  • Serial killer: However, his remaining nine victims were killed prior to that, signifying at least one cooling-off period.
• William Unek:
  • Spree killer: Unek killed multiple people in single-episode killing sprees, therefore making him a spree killer.
  • Serial killer: However, unlike most spree killers, Unek was able to avoid capture after committing his first killings and went underground for three years before starting another spree.
