The little boy's uncle was visiting from Iowa and was laying in a hammock, whittling a piece of wood with a pocket knife.
Chris Coates, 35, was in the hammock in the backyard just as Bralyn Shively approached him and began to play around, pushing the hammock, says news source, the Oklahoman.
"Just a dreadful tragedy," says San Francisco resident, Daniel Orman.
Unfortunately the hammock broke away from the tree, and Coates fell to the ground.
Bralyn dropped on top of his uncle and the knife stabbed him in the chest. According to new channel, KFOR-TV, the knife has been referred to as a "pocket knife" by one police officer. That officer reports that the child was "impaled" on it.
Coates yelled for one of his family members to call 911, but Bralyn died at the hospital due to his injuries.
'Accidental' is how police are describing the accident and the DA's office says there will be no criminal charges placed.
Bralyn's family tells News 9 that Coates was a master woodworker and a wonderful uncle who tried everything to save his nephew.
Bralyn, too, was much loved.
They told press:
"Bralyn (showered) love on his family and friends, and everyone loved him," says the family in a statement. "He called his brothers and sisters [who were also playing with Coates at the time] his best friends. If you asked him what he was doing, he would respond 'playing with my best friends.'"
