"Four people were killed and eight others were wounded in the rampage, which unfolded during Sunday morning services at the Church of Jesus Christ of Latter-day Saints meetinghouse in Grand Blanc Township, about 60 miles (97 km) northwest of Detroit,according to police.
The suspect, identified as Thomas Jacob Sanford, 40, from the nearby town of Burton, was shot dead in a parking lot outside the building about eight minutes after the carnage began, police said.
Hundreds of people were inside the meetinghouse - the Mormon faith's term for the place of worship they most often use - when the suspect rammed his pickup truck into the front doors of the building. Officials said he then sprayed the interior with a barrage of gunfire before deliberately setting the building ablaze.
Two victims were found shot to death, and two other bodies were discovered hours later in the charred ruins left of the building. Authorities had said late on Sunday they feared that additional remains might turn up."
