Summary based on the NamUs case record (MP7864) and 7 other sources
The disappearance of Ronald Joseph Stobierski is a perplexing case that began in the summer of 2003. Initially, he was reported missing on July 9, 2003, from the residence of his girlfriend, Bonnie Kelly, in Aurora, Illinois. However, as investigators delved deeper, the details surrounding his last known whereabouts became more complex. It was later clarified that while the initial report came from Aurora, Stobierski was actually last seen in Niles, Illinois. At the time he went missing, he was 44 years old, stood between 6'1' and 6'3', and weighed between 130 and 150 pounds. He had brown hair and brown eyes. He was possibly wearing a light-colored T-shirt, blue jeans, and white athletic sneakers. Distinctive features included a scar on his neck, another scar on his right forearm, and a tattoo of an unknown design on one of his shoulders.

Further investigation revealed that Stobierski's life before his disappearance involved several location changes. Prior to vanishing, he had been living in Dixon, Illinois. Before his time in Dixon, he was enrolled in a V.A. assistance program in Chicago. It was at the Hines Veterans Administration Hospital in Chicago where he and his girlfriend, Bonnie Kelly, met another patient named Joseph Lemmer. Kelly had been at the hospital seeking treatment after a suicide attempt. Following their meeting, both Stobierski and Kelly went to live with Lemmer at his home in Dixon. It was after this move that the couple was last seen, and they have not been heard from since.

The circumstances surrounding their disappearance from Dixon have led to troubling suspicions. Authorities received information that around the time Stobierski and Kelly went missing, fresh concrete had been poured in a barn on Joseph Lemmer's property. This has led to speculation that the couple may have met with foul play and could potentially be buried there. The case is being handled by the Kane County Sheriff's Office. The investigation into what happened to Ronald Stobierski and Bonnie Kelly has been ongoing for years, yet their disappearances remain unsolved. The overview of this case involves a man and his girlfriend who vanished after moving in with an acquaintance they met at a V.A. hospital, with the last known circumstances pointing to a specific location where foul play is suspected but unconfirmed.
