A man authorities say started a blaze when he was 12 years old that killed a firefighter at a community college library in Everett, Washington, pleaded guilty Thursday to first-degree murder. The Daily Herald reports that Elmer Nash, now 47, is a recently released convict with a long criminal history. According to court documents, Nash over the years repeatedly admitted setting the fire. Firefighter Gary Parks was killed in the Feb. 16, 1987, fire at Everett Community College. More than 100 firefighters responded to the large blaze that gutted the structure, and Parks was among the first to arrive and enter the building.
