Nearly a dozen people were stabbed at a Walmart in Traverse City, Michigan, Saturday afternoon, in what police are calling a “random” act by a lone attacker. Six of the injured were still in critical condition hours later.

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