A 12-year-old boy in Michigan stabbed a man four times in the back in a desperate attempt to save his mother from a domestic assault, authorities said.

Deputies from the Chippewa County Sheriff’s Office responded to a home on Lake George Road on Sugar Island about midnight on Monday after receiving reports of a domestic disturbance involving gunshots and a stabbing, WLUC reports.

Chippewa County Sheriff Michael Bitnar said the adult male suspect fired several rounds into the floor of the home during the alleged assault, prompting a 12-year-old boy to stab the armed man multiple times before running out of the house with his mother through a back door.

The suspect allegedly fired several shots at the woman and her son as they fled toward the St. Mary’s River, which separates Michigan from Canada. Both the boy and his mother were later found by responding officers in good condition.

The suspect was arrested several hours later and remained in custody as of early Tuesday, Bitnar confirmed to The Post.

“This case is still ongoing and the report is not finished yet,” Bitnar wrote in an email. “As you can imagine, this investigation has many moving parts and when it is complete, it will be sent to the prosecutor’s office for review for charges.”

The suspect had not yet been arraigned as of early Tuesday.

Investigators are considering multiple felony charges against the man, including felonious assault, aggravated domestic assault, reckless discharge of a firearm and felony firearm possession, WLUC reports.

Investigators do not believe the boy and the suspect are related, Bitnar said.
