What we know about the deadly shooting at a Michigan Mormon church

At least 100 federal investigators are responding to an attack in a Michigan community where a former Marine crashed a pickup into a Mormon church during a Sunday service, shot into the building and set it ablaze. It was the latest of many shooting attacks on houses of worship in the U.S. over the past 20 years, including one in August that killed two children during Mass at the Church of the Annunciation in Minneapolis. Hundreds of worshippers were inside the Church of Jesus Christ of Latter-day Saints in Grand Blanc Township at about 10:25 a.m. Sunday, when a man got out of a pickup with two U.S. flags raised in the bed and began shooting, according to law enforcement.
