Prosecutors want a year in prison and a $250,000 fine for convicted ex-Massey Energy CEO Don Blankenship, who ran a West Virginia coal mine that was the site of a deadly explosion.
In a sentencing memorandum in federal court Monday, prosecutors said a shorter sentence could only be interpreted as declaring that mine safety laws aren't to be taken seriously.
Prosecutors wrote that Upper Big Branch Mine was a powder keg 1,000 feet below the surface, primed to blow at any time. The mine exploded in 2010, killing 29 men.
Blankenship was convicted Dec. 3 of a misdemeanor conspiracy to willfully violate mine safety standards at the mine.
In their memorandum, Blankenship's attorneys say he shouldn't receive more than probation and a fine. They say they intend to appeal. Defense attorneys included letters from people commending him.
