"He should go to jail today. I don't think there should be a waiting period," Quarles said. "He's had long enough."
But Quarles wants to see more people behind bars -- not for advance warnings -- but for their role in the disaster that took his son.
"We need people to go to jail for the explosion that killed 29 good, innocent men," he said. "That's what I'm looking for."
Jonathan Hughart, 32, said his father is still cooperating with federal prosecutors but said the wrong man was in the courtroom.
"It should be Don Blankenship," he said. "Don Blankenship was a very strong influence on my father. He was always in fear of losing his job."
Upper Big Branch was the worst U.S. coal mining disaster in 40 years.
Four investigations found that worn and broken cutting equipment created a spark that ignited accumulations of coal dust and methane gas. Broken and clogged water sprayers allowed what should have been a minor flare-up to become an inferno.
The federal Mine Safety and Health Administration said the root cause was Massey's "systematic, intentional and aggressive efforts" to conceal life-threatening problems. Managers even maintained two sets of pre-shift inspection books -- an accurate one for themselves, and a sanitized one for regulators.
Hughart had faced up to six years under the law. His lawyers argued in June that he'd been unfairly linked to the disaster and asked the court for leniency in sentencing. They said his life had been ruined by the "terrible negativity" and publicity surrounding his case.
Hughart never contested his crimes but said none of his actions "can be linked to any actual mining injury."
Prosecutors, however, argued for a stiffer sentence because the conspiracy endangered miners' lives.
