Matchett matched the description of the armed man who had just held up the store.
The victim told deputies Matchett walked into the store and demanded cash from the register. She said he pointed a gun at her when she hesitated and asked why he was robbing her.
He "said he would have to answer to God for this," according to charging papers.
Deputies found a bag containing the stolen money and rings when they arrested him, records show.
Matchett has a prior conviction for second-degree burglary.
