WICHITA, Kan. (AP) — A man has been stabbed by the adult son of a woman he was arguing with in Wichita.

According to Wichita police Sgt. Roger Runft, police responded to a call about “a couple arguing” early Saturday morning. He says a 36-year-old man and a 39-year-old woman were arguing when one of the woman’s sons pulled out a knife and stabbed the man.

The suspect and his brother fled the scene.

Runft says the man suffered five cuts and two stab wounds and his injuries are serious, but not life-threatening.

Authorities say the woman’s two sons, who are 19 and 20, have not been located yet.
