Indiana officials are still trying to determine the cause of a blaze Friday that claimed the lives of a toddler and an infant.
The children's mother was burned trying to save them, according to TheIndyChanel.
Five-year-old Alle Abbott managed to escape and ran to a neighbor's for help, the station reported.
Serena Abbott suffered burns and was overcome by smoke while trying to save her kids.
"I backed out. I just got scared and then I saw Serena and her hair was burnt and her face was black," a neighbor of the victim told RTV6.
Abbott was taken to the burn unit at Wishard Hospital in Indianapolis.
Firefighters recovered the bodies of John, six months, and Haley, 18 months, on Saturday morning.
A neighbor whose daughter was at the victims' apartment before the fire began said there were candles burning in the living room, but it's unknown if that was the cause, the station reported.
"We don't believe this will be a criminal investigation," Johnson County Sheriff Doug Cox told reporters.
Investigators say it could be weeks before they determine a cause for the fire.
