It's now four months later, but the only reference I could find on Google to the life or death of Frank Mullins was his obituary in the Bristol Herald Courier which mentioned that "Franklin Shane Mullins, age 25, formerly of Haysi, passed away May 14, 2004, due to a job-related accident."
Incidentally, Merriam-Webster defines "accident" as:
1 a : an unforeseen and unplanned event or circumstance b : lack of intention or necessity : CHANCE
2 a : an unfortunate event resulting especially from carelessness or ignorance
So was the death of Frank Mullins an accident?
