RAYTOWN, Mo.–A northern Missouri child was stabbed after police say he and his grandfather got in an argument over a doughnut.

It happened in Raytown, Mo. Tuesday morning.

Neighbors say the 12-year-old came running out of the house– screaming, bleeding, and holding his right arm.

The woman who called 9-1-1 said the boy told her his grandfather stabbed him.

“I opened the door, saw a little boy there with his arm wrapped up and saying his grandpa tried to kill him and stabbed him in the arm, and he needed help,” said Dana Payne, the 911 caller. “And then he kept going ‘Why’d my grandpa try to kill me? Why’d my grandpa do it?'”

Raytown police confirmed the grandfather was involved, and that he had left the scene before they arrived.

He is now charged with first degree assault and armed criminal action.
