The indictment says on March 12, 2016, that Shelton possed a Colt Model M4, a .22 caliber rifle, knowing that he had been previously convicted of a crime.

When reached for comment, the DA’s office said:

“The defendant is classified as a felon not to possess a weapon and the charge is appropriate.”
