MOUNT PLEASANT, Mich. —  A 12-year-old boy stabbed his sister in the arm in an argument over a chicken pot pie, authorities said.

The boy is charged as a juvenile with assault with intent to do great bodily harm less than murder and assault with a dangerous weapon, said Robert A. Holmes, senior assistant Isabella County prosecutor.

The alleged attack took place Monday evening at the siblings' home in Mount Pleasant.

"They were having a brother-sister argument," Officer Michael G. Covarrubias told The Saginaw News for a story Wednesday. "This is going to make them sound stupid, but they were arguing over a chicken pot pie."

When the 13-year-old girl refused to give up the microwavable pie, her brother drew a nine-inch folding knife and attacked, Covarrubias said.

"They were just arguing over the pot pie, and she said her brother became very upset and pulled out this knife and swung at her," he said. "It appeared she put her arm up to block it, and then she got stabbed."

Medics treated the girl at the scene for an inch-long forearm gash, Covarrubias said. The siblings' 35-year-old mother apparently broke up the fight and called police, he said. Authorities did not release the mother's or children's names.

The boy was ordered held in a youth home in neighboring Osceola County pending a Feb. 23 pretrial conference. He faces anywhere from probation to detention until he turns 19, Holmes said.
