Salt Lake Fire Capt. Roy Anderson said the fire at the Hawthorne House, 379 E. First Ave. (50 North), was accidentally ignited by an apartment tenant while smoking. He said a mattress was in flames when firefighters arrived at the scene.The tenant suffered a minor laceration to a hand while trying to get a fire extinguisher. "We suspect it was a cigarette," Anderson said.
