A Pottawattamie County man was severely injured on the night of Friday, July 4th, when a firework detonated in his hand. Cole Mayer, 30, of Council Bluffs, was apparently trying to light a large firecracker, known as an “M-80”, when it went off in his hand. Pottawattamie County Sheriff Jeff Danker was quoted as saying “It pretty well took that hand off at the wrist.” A helicopter flew Mr. Mayer to the University of Nebraska Medical Center in Omaha. The accident occurred in rural Council Bluffs, in the 13000 block of 220th Street. M-80s are illegal in Iowa. The accident remains under investigation.
