Sue Walsh

"I moved into your perfect little house, your perfect little street. Everybody told me that I lucked out, that I got myself a good family. Well I had a good family, I didn't want yours."

Sue Walsh is a killer who orchestrated the disappearance of Gabby Hoffer, who appeared in Gabby.

History
When she was eight, Sue's parents died, and she was sent to live with her cousin Kate and the latter's parents. However, Kate's father molested Sue, which traumatized her and caused her to develop psychopathic tendencies and a jealousy against Kate, who never received any of the sexual abuse and was unaware of it, upholding her father as a good man. As an adult, Sue decided to take revenge against Kate by having her daughter, four-year-old Gabby, abducted. She initially tried to recruit her boyfriend Ian Little and Kate's ex-husband Doug Hoffer, but the latter apparently refused and tried to call the authorities, forcing Sue to kill him. Ian then disposed of Doug's body. Meanwhile, Sue decided to change her plan, instead contacting an online forum specializing in "disrupted adoption", a relatively new type of crime that involves children being quickly given away by overwhelmed adoptive parents to offenders who pose as adoptive families. She eventually sealed a deal with one of her contacts, Nicole Jones, who agreed to take Gabby.

In "Gabby", Sue took a sleeping Gabby to a convenience store, where she purchased a number of food and drinks in a rush, while Nicole abducted Gabby outside. When Sue goes back outside and sees that Gabby is gone, she feigns horror and screams for help. The BAU, called in to assist in the investigation, believed her to be innocent, instead suspecting Doug of being behind Gabby's disappearance. Their suspicions are disproved when Doug's body is shortly discover. Then, security footage reveals that Sue was seemingly waiting for someone before entering the convenience store; that and the fact that she didn't park her car near a light (the typical behavior of a protective mother) lead to the agents suspecting Sue. After Sue attacks Hotch in a fit of rage when he accuses her, the BAU deduces from her behavior that she was indeed responsible. Later, Kate offers to interrogate Sue herself, and when she does, Sue reveals her motives and tells her that Gabby is gone. She isn't seen for the rest of the episode, but the BAU later deduce that Sue was lying in order to further the psychological torture on Kate, and are able to rescue Gabby from Michelle Fader and Michael Feehan.

Modus Operandi
When she killed Doug Hoffer, Sue bludgeoned him to death with a candle holder.
