Garland Allen is charged with second degree murder of his wife Tracy, which could be amended to first-degree.
Altus Police Chief Tim Murphy says in December, Allen led authorities to his wife's remains in a remote area north of Snyder, near Tom Steed Reservoir.
District Attorney John Wampler believes Tracy may have been killed in 2001 during an argument in Allen's trailer.
