Police said the boy was found hanging and no foul play is suspected by authorities in his death.
Relatives of the third-grader had noticed a change in Jackson's behavior and say Sophia Soak Creek Elementary school bullies, who sometimes waited to torment him by his trailer park, caused the child to take his own life.
'I was spending time with him, trying to get it out of him. But Jack's the type that holds things in and I couldn't get to him,' said Jackson's grandmother and guardian, Betsy Baber.
Baber said Jackson tried to fend off the bullies with humor and sometimes by force although he had lost he desire to fight them in recent weeks. His grandmother also helped build him a clubhouse to help him make more friends.
I don't know what he was thinking,' Jackson's uncle Shane Baber said. 'He wanted to spend the night with me for two days and I couldn't figure out what was going on.'
On Saturday afternoon the boy's sister found her brother's body in his room after she went to cheer him up with a frog she had found outside.
His mother Diana Crump said: 'We came straight over. I saw the ambulance go that way and I said, "Turn around! Turn around! That's Jackson!" When I got to the hospital they wouldn't let me in so I knew when I saw EMS crying that he was gone.'
'Based upon the examination of the scene and interview of various witnesses and neighbors foul play is not suspected,' according to the Raleigh County Sheriff's Office.
Jackson's body was sent to the West Virginia Medical Examiner's Office for examination.
