The Mill Creek Killer

The Mill Creek Killer&#160;is a serial killer who appears in the episode The Last Word.

History
Like his polar opposite The Hollow Man, a lot remains unrevealed about the Mill Creek Killer, even after his arrest. The two would more or less compete with each other in a form of rivalry and even communicate using personal ads under the alias' "Sunny" and "Holden", references to the novel The Catcher in the Rye. At the time of the beginning of&#160;The Last Word, Mill Creek had killed 6 women. Eventually, with a little help from The Hollow Man, the BAU were able to catch him by having a live&#160;woman matching Mill Creek's victimiology pretend being a victim of a copycat murder commited by The Hollow Man and left in the woods as a gift. When questioned by Gideon, Mill Creek confessed to all murders when Gideon threatened to reveal his necrophiliac activities with the corpses.

Modus Operandi
The Mill Creek Killer targetted educated, middle class women. He would kill them&#160;using blunt force head trauma, abduct them and hide their bodies in woods under leaves and other debris in order to be able to revisit them later and apply makeup, groom their hair and engage in sexual activities with them.
