From Fox News:
At least 11 people are in the hospital after a stabbing Saturday afternoon at a Michigan Walmart. Grand Traverse County Sheriff Michael Shea said a 42-year-old man, acting alone, entered the Traverse City store and used a folding knife to stab nearly a dozen people.
The suspect, who authorities have not publicly identified, was taken into custody without injury within minutes. Citizens in Walmart also helped to apprehend the man and treat victims.
