Police initially suspected her ex-boyfriend, Cornelius Bighetty. His name was cleared after successfully passing a lie detector test. She and Cornelius had an argument earlier in the evening at the Cambrian Hotel. During the initial days of the investigation, attention was placed on Betty's friends. Unfortunately, unacceptable recording and preserving of evidence at the Pump House (the crime scene) seriously crippled the investigation. Dwayne Archie Johnston, James Robert Paul Houghton, Lee Scott Colgan and Norman Bernard Manger, four young men from The Pas, were eventually implicated in her death. However, it was not until December 1987, sixteen years after her death, that any of them were convicted of the crime. It was at this time that Constable Rob Urbanowski took over the investigation and placed an ad in the local newspaper asking for witnesses to come forward. Even then, only Johnston was convicted, as Houghton had been acquitted, Colgan had received
immunity for testifying against Houghton and Johnston, and Manger was never charged. The
Aboriginal Justice Implementation Commission conducted an investigation into concerns surrounding the length of time involved in resolving the case. According to the Commission report, Osborne's autopsy showed that "along with well over 50 stab wounds, her skull, cheekbones and palate were broken, her lungs were damaged, and one kidney was torn. Her body showed extensive bruising." The Commission concluded that the most significant factors prolonging the case were
racism, sexism and indifference of white people. The
Royal Canadian Mounted Police officially closed the Osborne case on February 12, 1999. == Aftermath ==
