Summary based on the NamUs case record (MP5409) and 9 other sources
Bonnie Rae Kelly, a 41-year-old woman, was reported missing on July 9, 2003, from Aurora, Illinois. At the time of her disappearance, she was described as a white female with red/auburn, medium-length, curly hair and brown eyes. She was approximately 5 feet 7 inches to 5 feet 9 inches tall and weighed between 135 and 150 pounds. When last seen, she was wearing an oversized white t-shirt with writing on it, blue jeans, and white sneakers. She also wore prescription glasses made by Paris. The initial report stated she was missing from her residence in Aurora, but it was later clarified that she had been living in Dixon, Illinois, before she vanished. Prior to her time in Dixon, she had been at a V.A. assistance program in Chicago.

The circumstances surrounding Bonnie's disappearance are complex and troubling. She was not alone when she went missing; her boyfriend, Ronald Stobierski, also disappeared at the same time. The couple's history indicates a period of vulnerability for Bonnie, who had previously sought treatment at the Hines Veterans Affairs Hospital in Chicago following a suicide attempt. It was at this hospital that she and Ronald met another patient, Joseph Lemmer. After meeting Lemmer, both Bonnie and Ronald went to live with him at his home in Dixon. It was from this point that neither Bonnie nor Ronald were heard from again. The case is classified as an endangered missing person case, partly due to Bonnie's history of mental health challenges.

The investigation into their disappearance has uncovered unsettling details. Witnesses reported that around the time Bonnie and Ronald went missing, Lemmer had fresh concrete poured in a barn on his property. This has led to speculation that the missing couple could possibly be buried there. Joseph Lemmer has since passed away, adding another layer of difficulty to the investigation. The Kane County Sheriff's Office is the investigating agency for Bonnie's case. Despite the passage of time, the case remains unsolved, and the whereabouts of Bonnie Rae Kelly and Ronald Stobierski are still unknown, leaving their families without answers.
