CIMARRON COUNTY, Okla. (KFOR) -- Two men who pleaded no contest to murdering a 77-year-old Oklahoma man outside a convenience store will spend several years in prison for the crime.
In June 2013, 77-year-old Charles Nieman and his wife stopped at the Loaf-'n-Jug convenience store in Boise City to get gas.
Authorities say Nieman was outside his vehicle when a man walked up to him and demanded his wallet.
Nieman, who investigators say was hard of hearing, turned to his wife and asked her what the man said. That is when the man shot Nieman in the head, according to the Oklahoma State Bureau of Investigation.
Nieman was rushed to the hospital where he was pronounced dead.
For several years, investigators struggled to gain any ground in the case.
In February, officials with the Oklahoma State Bureau of Investigation announced that Timothy Erish Dees and Zachery Lee Wilson were taken into custody in Alabama.
