His mother, Mary Hobbs, confirmed the tragic news in a statement provided to the Sun.
"He was just moving [the ATV] from one parking spot to the next for me, so I could back into park," she said.
"He pulled [in] front of me to park the ATV and the ground gave way from all the rain and mud."

Sean suffered severe head injuries after the ATV flipped over, according to his mother.
She recalled: "I ran to neighbors trying to get someone to help me get the ATV off of him. No one answered. I ran back to him.
"By that time, I realized he wasn't alive anymore."
The grieving mom went on to say she 'laid next to her son until an ambulance arrived at the scene'.

Hobbs added: "There was a huge part of my heart that died with my son on Wednesday.
"He was my only son, my rock, my strength when I had none left. We loved spontaneously jumping in the car for a road trip or a beach sesh. We bonded over music, fast cars and shooting guns and taking new adventures.
"Sean brightened my world in a way no one else could ever come close to. He was my baby boy, my squishy, my heartbeat."
Watauga County Sheriff's Office Major Kelly Redmon told the Watauga Democrat that Sean had been identified as the victim after the Watauga Medics, the Boone Fire Department, and the Watauga County Sheriff’s Office responded to the fatal incident.
