The mystery of what caused a fatal southeast Salt Lake City house fire will go to the grave with the victim.
Salt Lake City Fire Capt. Tom Burckhard said investigators have given up trying to determine the cause of the Tuesday blaze that caused more than $100,000 in damage to the home of John Newsome, 81, who died shortly after being pulled from the 665 Wilson Ave. (1750 South) residence by firefighters.
"The fire is no longer under investigation and will go down as being of an 'undetermined' cause," Burckhard said Thursday. "Mr. Newsome was our only witness, and the damage to the house was so extensive we just cannot find the cause."
