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.

Here's what we know about the shooting victims.

John Bond

John Bond, 77, was one of four congregants killed in the attack, according to a GoFundMe created by his family. Bond, a Navy veteran, was remembered as a devoted husband, father, and grandfather.

Bond served nine years in the U.S. Navy and remained active in his community, the GoFundMe page states. The fundraiser described him as “a lover of golf and trains,” who cherished time with his grandchildren.

"He was a well-known and loved member of his family and active in his community," the family wrote. “(He) always loved spending time with his family and grandkids."

The Detroit Free Press confirmed with GoFundMe that the fundraiser is legitimate. Donations are expected to cover memorial costs and support Bond's wife, Joanne Bond.

What we know about the victims

According to Renye, two of the dead victims were shot. At least two others were believed to have been trapped inside the church when the fire started and perished in the flames.

Eight people ranging in age from 6 to 78 were treated for gunshot wounds and smoke inhalation, according to Dr. Michael Danic, medical chief of staff at Henry Ford Genesys Hospital.

Five people were treated for gunshot wounds, including one patient who died in the emergency department, Danic told reporters on Sept. 29. Another person remains in critical condition, and a child who was stabilized was then transferred.

Two of the patients treated for smoke inhalation have been discharged, and the third is still intubated, he said.

Community member: 'My heart just breaks'

Stephanie Giddings, of Fenton, Michigan, went to the reunification site to be close to her fellow church members, the Detroit Free Press, part of the USA TODAY Network, reported. She said she had to leave work early because she was shaken up.

"They're family," she told the Detroit Free Press, noting that her daughter had been baptized recently at the chapel. "I'm in complete disbelief, and my heart just breaks."

"Places of worship are meant to be sanctuaries of peacemaking, prayer and connection," Doug Andersen, a church spokesman, said in a statement. "We pray for peace and healing for all involved."
