JEROMESVILLE, Ohio - Authorities say three children killed in an overnight house fire in rural north-central Ohio died from smoke inhalation.
Fire officials say three other people who were in the house have been hospitalized with what appeared to be non-life-threatening injuries.
The State Fire Marshal's Office says the fire started on a front porch.
The Associated Press reports there was an incubator on the porch; however, fire officials told FOX 8 News that has not yet been determined. They are still working to determine the actual cause.
Officials identified the children who died as 12-year-old Faithlyn Bogavich, 4-year-old Delaney Bogavich and 1-year-old John Jeffrey Bogavich.
The others injured included a 13-year-old boy.
The two-story house in Jeromesville was fully engulfed in flames when firefighters arrived at the scene about 70 miles southwest of Cleveland.
At least six fire departments responded.
