MANSFIELD — The mother of a 5-year-old boy who died inside a hot car in June 2025 remained in the Richland County Jail on Wednesday after her arraignment on three felony charges .
Kiarra Brock, 31, of Mansfield was indicted by a county grand jury this month on charges of involuntary manslaughter, reckless homicide and endangering children, according to court records.
Richland County Common Pleas Court Magistrate Mackenzie Mayer set bond at $75,000 cash and surety plus personal recognizance bond. Electronic monitoring was ordered if Brock is released, along with no unsupervised contact with minor children.
Brock was still in jail on Thursday morning, according to jail records.
Involuntary manslaughter is a first-degree felony. Reckless homicide and endangering children are both third-degree felonies.

Victim suffered from ‘elevated body temperatures’
Brock’s son, Kyrie Brown, suffered from “elevated body temperatures” in the moments leading up to his death on June 26, Mansfield police said at the time of the incident.
Police records show the initial 911 call was placed at 3:05 p.m., by Brock. The first police officer arrived at 3:07 p.m. Backup arrived by 3:22. A total of 10 Mansfield police officers responded to the incident.
Brock told a dispatcher she had left her “baby in the car” across from Mansfield Memorial Homes.
Brown was unresponsive and life-saving measures were immediately started by both police and fire personnel.
He was transported to a local hospital, where he was later pronounced dead.
An investigation indicated the child had been left unattended in the mother’s vehicle for an extended period of time. It appeared the boy had been left inside the car while Brock went into Mansfield Memorial Homes to work that morning.
Mansfield police investigated the incident with the Richland County Prosecutor’s Office and Richland County Children Services.
35 children died inside hot cars in 2005 across USA
According to the website kidsandcars.org, 35 children died after being left inside vehicles in the United States in 2025.
According to the National Highway Traffic Safety Administration website, more than 1,010 children nationwide have died from heatstroke after being left or becoming trapped inside a hot car in the last 25 years.
In 2024, 39 children died of heatstroke in vehicles — up 35 percent from 2023.
According to the website, a child’s body temperature rises three to five times faster than an adult’s. When a child is left in a vehicle, that child’s temperature can rise quickly — and the situation can quickly become dangerous, the NHTSA said.
Heatstroke begins when the core body temperature reaches about 104 degrees. Death occurs at a core body temperature of 107 or above, according to the website.
In the summer, a car’s interior can become dangerously hot, reaching temperatures far exceeding the outside air temperature.
Even on a mild 70-degree day, a car’s interior can reach nearly 120 degrees after just 90 minutes, according to www.scottsauto.com.
On a 100-degree day, the temperature inside a car can reach 119 degrees Fahrenheit in just 10 minutes, the website said.
