At least 11 people have been stabbed at a Walmart in Michigan in what the local sheriff says appears to have been a random attack. A suspect is in custody.

COLLINSVILLE — A 19-year-old Walmart employee here stabbed a coworker because he felt "disrespected," according to charges filed this week. On May 7, federal investigators sent a subpoena looking into the relationship between Montgomery and a man named Malik Taylor.
