|“||What's the psychopath got in the bag, Jason?||„|
|~ Frank Breitkopf|
Frank Breitkopf is Agent Jason Gideon's archenemy and a prolific serial killer in Criminal Minds. He is the main antagonist of Season 2.
Frank never knew his father and his mother Mary Louise Breitkopf was a German immigrant prostitute living with him in Manhattan, he would always watch his mother having sex with her clients. After possibly killing Mary, he started to kill people by vivisecting them while travelling. He soon met a woman named "Crazy" Jane Hanratty, and because she showed no fear when he was about to kill her, he spared her life. He would occasionally give her wind chimes made of the bones from his victims' ribcages.
Meeting Jason Gideon
After the BAU Agents were sent to investigate the deaths of his victims and the disappearance of Sheriff Georgia Davis, he was found by Agent Jason Gideon and Agent Derek Morgan while at the diner drinking his signature strawberry milkshake. After a conversation with them, Georgia was found by the authorities, traumatized inside Frank's trailer. Frank then says that he will give Gideon the location of a bus full of children he had kidnapped earlier, but only if he could leave with Crazy Jane, Gideon agrees.
Frank eventually murdered Gideon's girlfriend Sarah Jacobs and later Randall Garner's daughter Rebbeca Bryant. He also kidnaps serial killer Jeffrey Charles' would-be victim Tracy Belle. During a confration between Gideon and Breitkopf & Hanratty, realizing he would be arrested, he grabbed Jane and jumped in the front of a train, killing both Jane and himself. The murder of Sarah Jacobs as well as Frank himself would continue to haunt Gideon for the rest of his life, up until his death in Nelson's Sparrow.
