He won the NBC TV show and its one million dollar prize in 2008.
After winning America's Got Talent, Neal recorded one album titled My American Dream.
Boyd died at his mother's house in Sikeston, Missouri on Sunday night, according to Scott County Coroner Scott Amick. "So sad. Rest peacefully, Neal E. Boyd".
One year ago, Boyd and his mother were involved in a serious vehicle accident in Scott County, after running off the right side of the road, striking a tree. "I shattered a lot of bones, and shattered my hip, which has left me nearly unable to use that leg for now", Boyd told the Southeast Missourian in February. "It's been hard, because you can't get up on stage right now, you can't perform for the audiences and you can't really do too much recording or traveling".
"You never know what's going to happen next. When God's given you the time to rebuild your spirit and rebuild your body", the singer said.
Neal was rushed to hospital in a serious condition along with his mother, but both made a full recovery.
He was also very involved in politics and campaigned for a Missouri District 149 House Seat in 2014.
