Gary May will be sentenced in federal court Thursday. He's cooperating with prosecutors in their ongoing criminal investigation of the 2010 explosion that killed 29 miners at the former Massey Energy operation.
May pleaded guilty last March. He was accused of defrauding the government through his actions at the mine, including disabling a methane gas monitor and falsifying records.
