An Ohio mother lost five family members, including her four young children and their grandmother, in a suspected carbon monoxide poisoning incident that occurred while they were waiting for assistance with a flat tire. The incident took place on Wednesday when the car, occupied by Adriana Coleman's children and their grandmother, Candace McAllister, became filled with the odorless gas at levels described as "five times the lethal limit."

The victims included Coleman's four-year-old twins, Liberty and Legacy, three-year-old Storm, and two-year-old Stone. Their grandmother, 36-year-old Candace McAllister, also died. The children's father, Kesaun Coleman, discovered the unresponsive family members after his mother called him for help with the flat tire. He immediately called 911, and first responders attempted life-saving measures, but they were unsuccessful.

Authorities stated that the car's windows were closed and the air conditioning was running when the lethal gas silently filled the vehicle. According to Coleman, a detective informed her that the carbon monoxide levels detected in the car were five times the lethal limit.

Legacy, known as 'Ace,' was the last to pass, surviving for nearly two days before Coleman made the difficult decision to take him off life support on Friday. Coleman expressed her profound grief, stating, "I’m here, but I have no idea what’s going to happen after I walk out these hospital doors. I just want my babies."

When the children's father, Kesaun Coleman, arrived, he found all five family members unconscious inside the vehicle and called 911

In a heartfelt Facebook tribute, Coleman wrote about her devotion to her children, saying, "There is absolutely nothing that I enjoyed, loved, fought harder to be aside from being a mommy. And the kids I was given made that so very easy." She also lamented the loss, stating, "I've lost everything I've put my all into over the last five years."

Kesaun Coleman also shared his devastation on Facebook, recounting, "Woke up yesterday, was on my way to get the kids and sit with my mom and figure out a tire. But instead I pulled up to my mom and kids gone. I'm beyond crushed."

Coleman's mother-in-law, 36-year-old Candace McAllister, was also killed

McAllister had been driving the children when the flat tire occurred. The Toledo Police Department initially reported an "active hazmat incident" in the area before investigators determined the cause to be accidental carbon monoxide poisoning. Toledo Fire Chief Allison Armstrong noted that hazmat crews responded due to the unknown nature of the situation.

The Toledo Fire Chief said they had a hazmat respond to the scene 'because we didn’t know what we were dealing with'

The family is seeking financial assistance for funeral costs, as they reportedly did not have life insurance. Donations can be made to the Coleman-McAllister Fund at any Fifth Third Bank branch.

Toledo Mayor Wade Kapszukiewicz issued a statement expressing condolences, saying, "Today, a family experienced a tragedy that no family should ever have to endure. Our hearts are with this family as they face an unimaginable loss."

While foul play is not suspected, law enforcement is conducting a thorough investigation to ascertain the exact circumstances of the incident. Toledo Police spokesperson Sgt. Mohamad Nasser stated, "Our thoughts continue to be with the family and loved ones affected by this heartbreaking tragedy."
