DETROIT — A close-knit church community in central Michigan is mourning the loss of four people who were killed on Sept. 28 after a gunman opened fire during morning services and set fire to the church.

The shooting occurred as hundreds of people were attending Sunday services at The Church of Jesus Christ of Latter-day Saints in Grand Blanc, a suburb of Flint, Michigan. The incident sent shock waves throughout the community as families and church members rushed to the nearby NCG Trillium Cinema to reunite with their loved ones.

The victims injured in the incident were transported to a local hospital, said Grand Blanc Township Police Chief William Renye. As of 12:30 p.m. ET on Sept. 29, one patient treated at a local hospital remained intubated and another was in critical condition.

Authorities have not publicly released the names of the victims killed in the attack, but families and friends have begun to identify their loved ones. On Sept. 29, Michigan Gov. Gretchen Whitmer ordered flags lowered to half-staff statewide to honor the victims.
