Police arrested a 42-year-old man, Bradford James Gille, 42, of Afton, Mich., in the Saturday stabbings of 11 people in a Traverse City, Mich., Walmart.

After nearly a dozen people were stabbed at a Walmart in Traverse City, Michigan, Saturday afternoon, the quick actions of a couple of Marines and other bystanders helped stop the attacker from causing further harm.

The man was captured in three minutes thanks to "citizen involvement," Grand Traverse County Sheriff Michael D. Shea said.
