Sarah Danlin

Sarah Danlin is a serial killer who appears in the episode Jones.

History
Sarah Danlin was a medical student at Tulane University. One night she was in a bar called "Jones" with some friends during Mardi Gras. A man flirted with her and managed to lure her away from her friends to an empty pool room where he and a friend raped her. She pressed charges, but the detectives investigating the case, William LaMontagne Sr and J. R. Smith, were in disagreement regarding the credibility of her story. LaMontagne believed her while Smith, who knew one of the offenders, convinced her to drop the charges on the grounds that it most likely wouldn't lead to a conviction. She later dropped out of medical school on 24 February 1998.

When Sarah started killing Detective LaMontagne had been transferred from sex-crimes to homicide and investigated her first three murders. Eventually obsessing over the case, he refused to leave New Orleans, despite the arrival of Hurricane Katrina. One night, while looking over the notes, crime scene photos and letters regarding the murders, he realized when he noticed a bar stamp on the hand of a victim; the mark of Jones, the bar in which Sarah was raped. Just after he realized it, a tree was flung by the storm into through a window, mortally wounding him. He managed to use a piece of broken glass to carve the name "Jones" into the wall before dying. The storm also washed away the bodies of the first three victims, the autopsy reports and all of the evidence.

Sarah was transferred to Galveston, Texas during Katrina where she killed another man. Sometime after returning to New Orleans, she began terrorizing the French Quarters, where Jones, now renamed Mon Cherie, was. LaMontagne's son, Detective William LaMontagne Jr., was investigating the crime and called for the BAU. After a long investigation and a number of murders, they were able to track down Sarah to a motel where she was about to mutilate a man. Held at gunpoint, with a knife in her hand, Sarah suggested that the BAU kill her, but was talked into surrendering by LaMontagne Jr. when she found out that his father, whom she deeply respected, was killed in Katrina.

Modus Operandi
Sarah would lure away men from crowds, pubs and the like by seducing them with promises of sex. Once alone with the victim in a semi-public place, she would slash their throats in a manner similar to Jack the Ripper, whose killings she copied. She would also write letters written in a language similar to the Ripper's.

Profile
The killer was originally profiled to be friendly, agile, in the age of 30-35 and suspected of being a homosexual male with low self-esteem, which would be well hidden. He'd kill to reclaim his power and dress impeccably to keep the facade. Because he overcompensates to hide his insecurity, he most likely holds a position of authority at work and probably has some kind of medical training and may thus be a doctor, EMT, veterinarian or such. Unlike Jack the Ripper, an impateous lust killer, this offender would be organised, calculating and maybe even stalk his victims for days beofre the murder. He might identify with Jack the Ripper because he'd lost his own identity, maybe through years of child abuse or a single catastrophic event.

The profile was mostly correct, except Derek later realized that the UnSub was a woman.
