Authorities in Michigan say search crews did not find any additional bodies inside a Church of Jesus Christ of Latter-day Saints chapel where a former Marine opened fire and set the building ablaze, killing four people.

Police had feared they would find more victims in the charred wreckage but now believe everyone is accounted for after Sunday’s attack.

Investigators are focusing on what motivated the former Marine to ram his pickup truck into the church in Grand Blanc Township.

The suspect was killed while exchanging gunfire with two officers. Eight other people were treated at a hospital, including five with gunshot wounds.
