Two children from Minnesota visiting their aunt in Ohio died in a house fire early Tuesday.
NBC 4i in Columbus reports 12-year-old Kathryn Foster and her brother, 10-year-old Aaron Foster, were still with their aunt after asking to extend their trip one more day.
A fire started at the home early Tuesday – their aunt and her adult son made it out, but the two children were trapped inside, the station says.
According to the Columbus Dispatch, neighbors tried to break down a door they believed the children were behind with a sledgehammer. But neither they, nor firefighters, nor the kids' aunt could get to them.
The cause of the fire hasn't been determined, but it appears to have started in the basement where the woman's son stayed, the paper reports.
A GoFundMe campaign to held the children's mother has been started, and hopes to raise $5,000 to help with living and funeral expenses.
More than 1,100 people have died in home fires so far this year, the U.S. Fire Administration says. Sixty of those deaths have occurred in Ohio, while 13 have happened in Minnesota.
The National Fire Protection Association says the leading cause of civilian home fire deaths was smoking. The second most common cause was heating equipment.
