Six people were shot and killed and several others wounded in Michigan on Saturday night in a series of apparently random shootings, Reuters quoted authorities as saying. Authorities said they had the suspected gunman in custody. The Kalamazoo Department of Public Safety said on its Facebook page that six people had been shot and killed and several others seriously wounded in three shootings in Kalamazoo County, in southwest Michigan. "We seem to be dealing with a worst-case scenario, someone driving around shooting," Kalamazoo County Undersheriff Paul Matyas told NBC News earlier. At least three people were wounded in the attacks.
