The former CEO of Patriot Coal was gunned down in a cemetery in West Virginia on Monday.

Local law enforcement said Tuesday evening that an Ohio man connected to the shooting of Bennett K. Hatfield was in custody.

Hatfield, 59, resigned as president and CEO of Patriot Coal just weeks before the coal company filed for bankruptcy for a second time in 2015.

Hatfield was the chief executive officer of the International Coal Group in 2006 when an explosion at the Sago Mine in the northern part of the state killed a dozen miner workers, according to the Associated Press.

The local sheriff did not disclose a motive in the shooting after arresting Anthony R. Arriaga of Delphos, Ohio.

Police found a gun on a river bank near the cemetery. They believe he snuck along the river to escape to Ohio after the shooting.

He was arrested Tuesday in Ohio and waived his right to an extradition hearing. His bail is set at $1 million.
