May pleaded guilty Thursday before U.S. District Judge Irene Berger in Beckley to conspiracy to defraud the federal government. The charge stems from his actions at the former Massey Energy mine where 29 men died April 5, 2010.

Prosecutors say May disabled a methane monitor, falsified records and manipulated the ventilation system to fool inspectors.

May is the highest-ranking company official charged in connection with the blast.
