Overview

Michelle Yvette Busha, an 18-year-old from Bay City, Texas, was hitchhiking along Interstate 90 in southern Minnesota on May 26, 1980, when she was picked up, sexually assaulted, and strangled; her body was found four days later in a drainage ditch near Blue Earth in Faribault County. For years she was an unidentified Jane Doe and the killing went unsolved. The case broke not through forensics but through a confession: in 1988, Robert Leroy Nelson, an on-duty Minnesota State Patrol trooper at the time of the murder who was by then imprisoned in Texas, admitted to the killing. He pleaded guilty to first-degree manslaughter in 1989. The victim herself was not positively identified until 2015, when DNA from her exhumed remains matched a family sample, prompting the local sheriff to call it not a question of who done it, but who she was.

How it was solved

The murder was solved by the perpetrator's own confession rather than by physical evidence. In June 1988, while in custody in Smith County, Texas, Robert Leroy Nelson confessed to Faribault County investigators that he had killed the young hitchhiker found near Blue Earth in 1980. Investigators found the confession credible because Nelson supplied details that had never been publicly released, including that the victim's fingernails had been removed. He described having been on patrol as a Minnesota state trooper, watching traffic, when he saw a van drop off a young woman; he followed her, put her in his squad car, sexually assaulted and handcuffed her, and strangled her with a cord before leaving her body in a ditch off I-90. Because Nelson never learned or provided the victim's name, the case was solved as to the killer years before the victim herself could be identified; that final piece came in 2015 through DNA testing of her exhumed remains compared with a family reference sample.
