Sarah Anne Kolb was born on April 23, 1988, and raised in Milan, Illinois, where she lived with her mother and stepfather. She attended the Black Hawk College Outreach Center, an alternative education program in East Moline, Illinois, designed for students seeking a GED. Sarah was known among her peers as a dominant figure within the local Juggalo subculture, earning nicknames like "Queen of the Goths" and "alpha female." 

She was described as a habitual liar and had a history of self-harm, including being suspended from her previous school for such behavior. Sarah identified as bisexual and was known for her intense and sometimes volatile relationships. Her close friendship with Cory Gregory, who harbored unrequited romantic feelings for her, was a significant aspect of her social life. Sarah's complex personality and social dynamics played a crucial role in the events that unfolded in January 2005.

On January 21, 2005, Sarah Kolb invited Adrianne Reynolds to join her and Cory Gregory for lunch at a local Taco Bell. During the drive, Sarah confronted Adrianne about personal issues, leading to a heated argument. Upon arrival at the restaurant's parking lot, the confrontation escalated. Cory held Adrianne down while Sarah strangled her with a belt, resulting in Adrianne's death.

After the murder, Sarah and Cory transported Adrianne's body to Sarah's grandparents' farm in Aledo, Illinois. There, they attempted to burn the body using gasoline, but the effort was unsuccessful. They then enlisted the help of Nathan Gaudet, a 16-year-old acquaintance, who used a handsaw to dismember the body. The remains were placed in garbage bags and disposed of at the Black Hawk State Historic Site.

Adrianne's disappearance was reported when she failed to return home or show up for work. An investigation led authorities to Cory Gregory, who confessed to the crime and directed them to Adrianne's remains. Sarah Kolb was arrested and charged with first-degree murder and concealment of a homicide.

Sarah's first trial in October 2005 ended in a mistrial due to a hung jury. A retrial commenced in February 2006, resulting in her conviction on all charges. She was sentenced to 48 years for murder and an additional 5 years for concealment, to be served consecutively. Sarah Kolb is currently serving her sentence at Logan Correctional Center in Illinois.
