Another suspect, 20-year-old Anthony Arriaga of Delphos, Ohio, was arraigned May 26 on a first-degree murder charge.

The body of 59-year-old Bennett Hatfield was found May 25 at a cemetery where he had been visiting his wife's grave. His SUV was found nearby. Authorities believe Arriaga and Fitzpatrick plotted to steal Hatfield's SUV and sell its parts.

Hatfield resigned in 2015 as president and CEO of Patriot Coal.
