A member of the radical militia group Forever Enduring Always Ready, or F.E.A.R., had his sentence reduced Thursday after he cooperated extensively with the government against fellow members in the 2011 slayings of Tiffany York, 17, and Michael Roark, 19. Michael Burnett will now serve only eight years instead of 10 years, but he will still be on probation for 40 years. Burnett entered into a plea agreement Aug. 27, 2012, pleading guilty to a slew of charges surrounded the young couple’s death.
