"Enright's record shows that in 1983 he received a three-year deferred sentence. He claims he has since passed background checks to own the shotgun and the rifle that were seized by investigators on Wednesday. "
Dosen't the paperwork for a background check include some question like " Have you ever been convicted of a felony ? "
Since he was 17 at the time, unless he was tried as an adult, his record would have been expunged and the correct answer would be No.
