Michigan church shooting: What we know on the Grand Blanc attack that killed 4 people

Four people were killed and several others were wounded Sunday when, authorities say, a man opened fire at a Church of Jesus Christ of Latter-day Saints in Grand Blanc Township, Michigan, and set it ablaze in what a federal official called "an act of targeted violence." At least two of the four victims were fatally shot, police said. Five people were wounded by gunfire and three suffered smoke inhalation, said Dr. Michael Danic, the chief of staff at Henry Ford Genesys Hospital, where the injured were treated.
