Sauk County Sheriff's Office investigators examine the scene of a fatal shooting Aug. 8 south of Loganville.

(CNN)A 10-year-old boy accidentally shot and killed his brother during a game of 'cops and robbers' when, police say, he pointed a rifle he didn't know was loaded.

The incident happened Tuesday at a rural home in Loganville in Wisconsin's Sauk County.
The boy was playing with his 14-year-old brother and another child. They were toying with a rifle that had the magazine removed but, unbeknownst to the boy, still had a round in the chamber, the sheriff's office said.
    When the boy pulled the trigger, the bullet struck his older brother in the chest. He died at the scene.
