TRAVERSE CITY, Mich. (AP) — A man accused of entering a Walmart in Michigan and randomly stabbing 11 shoppers before being detained by bystanders in the store parking lot is expected to face terrorism and multiple assault charges, authorities said Sunday.

Grand Traverse County Sheriff Michael Shea said a motive behind the attack by Bradford Gille of Afton, Michigan, remains unclear. Gille, who Shea said had “prior assaultive incidents as well as controlled substance violations,†said very little as he was arrested. He is expected to be charged with one count of terrorism and 11 counts of assault with intent to murder.
