MANKATO, Minn. (WCCO) — A southern Minnesota man is in critical condition after police say he was stabbed by his son Wednesday afternoon.

The Blue Earth County Sheriff’s Office says deputies were called just after 1 p.m. to the 200 block of Eleanor Street in South Bend Township, in rural Mankato.

The 59-year-old homeowner reported that his son had a knife, and had assaulted him before. The dispatch operator also heard “an apparent struggle” happening while law enforcement were en route to the residence.

Deputies arrived to find the man’s 24-year-old son waiting outside, who “confirmed the disturbance.” He also told them he stabbed his dad, who was still inside.

The victim was rushed to an area hospital, and his son was taken into custody and is waiting criminal charges in the Blue Earth County Jail.

WCCO-TV does not typically identify suspects before they have been formally charged with a crime.
