Three people, including two young children, were shot with hunting rifles during the opening weekend of deer hunting season in Michigan.

The first incident occurred on Friday when a man discharged his hunting rifle by accident inside his Crawford County home and fragments from the bullet pierced his two sons, ages 4 and 6, according to the Detroit Free Press.

The dad was attempting to place the firearm into its cover when it went off.

Fragments from the bullet went through a wall and struck the siblings inside the kitchen. They were not seriously injured, the report said.

The second shooting took place at about 5:30 p.m. Saturday when a 29-year-old man mistook his younger brother, 28, for a deer and accidentally shot him with a muzzle rifle in a Boston Township cornfield, according to the Ionia County Sheriff’s Office.

The duo got separated while searching for a deer and the older brother fired when he heard what he believed to be the animal moving around nearby.

The elder sibling called 911 once he realized he hit his brother. The victim was airlifted to a nearby hospital in serious but stable condition.

No arrests were made in either incident.
