In 1992, 12-years after the discovery of the body, there was a real break in the case. On November 20, the Sheriff’s Department held another press conference in Charleston, this time to announce that they had determined the identity of the Airtight victim. Her name was Diana Marie Riordan-Small, a resident of Bradley, Illinois, who disappeared from her home a short time before passersby found her remains over 100 miles away in Coles County.
The revelation was the result of cooperation between Coles County Sheriff’s Detective Art Beier and Detective Steven Coy of the Bradley Police Department. Slowly, a picture of what happened to Diana Small began to emerge.
The reason no one matching the description of the body found at Airtight turned up in the missing persons reports was that no one reported Diana missing. “Her husband… told police he wasn’t all that concerned because Small had left home on occasions before,” the Journal Gazette reported. Diana’s mother and sister had joined a small Christian sect before moving west, where they became disconnected from Diana and her husband.
After nearly a decade, her sister, Virginia, left the church and moved to North Carolina. Virginia decided to get in touch with the rest of her family and learned of her sister’s disappearance, at which point she filed a missing persons report. According to Dave Fopay of the Journal Gazette, “Detective Art Beier saw the report on a national listing, realized Small’s descriptions matched that of the Airtight Bridge victim and contacted Bradley police.” A DNA test confirmed the match.
