On December 10, Dale Bradley Jr., a co-worker, kidnapped Ruff while the latter was performing his duties as a security guard at Kennecott Utah Copper. Bradley locked Ruff in his trunk and took him to a remote area where he shot him to death and buried him in a shallow grave. Ruff was considered missing until his remains were discovered in July of 1993. Bradley's guilt was belatedly discovered and proved; he was arrested and charged with the crime in September 2005. He was eventually convicted and sentenced to 40 years in prison.
