Susie was a roller derby captain who sported black hair on a side ponytail over her left shoulder, a roller skating helmet, and a roller skating t-shirt, both sporting the colors of her team, "Helter Skaters". Prior to Susie's fame as "Susie the Slayer", she was an ordinary woman who usually sported pink clothes, and a pair of monocles on her brown eyes plus a hairband at the right side of her head.
Amy and Hannah witnessed Susie being knocked unconscious by rival roller derby contestant Mona Middlefinger, which led the game to be suspended, and upon investigation, determined Susie to be dead due to being poisoned during the competition, grounds for Susie to be autopsied by Roxie right away. Finishing the job, Roxie deduced that an energy drink called "Rocket Cow" poisoned Susie to death due to the energy drink containing wanton amounts of caffeine, but Amy wondered as to why Susie would die of caffeine overdose. Roxie tested Susie for any allergies to caffeine and determined thus Susie was indeed allergic to caffeine, suggesting that Susie was not allowed to consume caffeine as ordered by her physicians. Since the killer rigged her bottle with the energy drink, Susie died of an anaphylactic shock (her airways had swollen at the point of preventing her from breathing) caused by her allergy. This made the message simple: the energy drink was the murder weapon. The killer was smart enough to rig Susie's lemonade with the energy drink, since Roxie deduced that the energy drink tasted like lemonade. Roxie also found a note in Susie's corpse telling the victim to take the drink, and with the paper unraveled in forensic powder, revealed that the killer played guitar.
Later on, Yann analyzed a crushed bottle containing traces of the energy drink that killed Susie at the skating rink with Susie's name on the bottle. Yann was able to determine the force of the crush by simulating the force required to crush the drink bottle, and thus deduced the killer weighed 132 pounds.
Killer and motives
The killer turned out to be her mother-in-law, Barbara Pickley
Barbara is very conservative-minded when it comes to how women are to be perceived, but felt that Susie's death was a difficult decision to make, although she confessed that she had no other choice. Barbara loathed roller derby skating as Susie made new friends and did not want to listen to her advice anymore. As she found out from Becky Walden that Susie was flirting with Lenny Spitfire, Barbara felt that Susie betrayed her trust by hanging around with Lenny (which was considered Susie cheating on Howard Pickley by her standards) and as thus caused Howard to ogle at other derby girls because of Susie participating in the roller derby sport. Barbara had to rig Susie's drink bottle with Rocket Cow Energy Drink, which was Barbara's only solution to make Howard stay away from the derby girls, but family values didn't have to include homicide, as the evidence which incriminated Barbara were grounds for her to face trial.
The Honorable Dante lambasted Barbara for domestic homicide, but Barbara defended her action by stating she had to protect Howard at all costs, not to mention the police were able to incriminate Barbara's traces throughout the case, which were grounds for a 25-year jail sentence for Barbara.
- Susie's death at the hands of her mother-in-law is one of the instances of domestic homicide in Pacific Bay.
