Officials explained that Elizabeth escaped the burning home on 2800 block of North 4th Street with other family members when she realized her son was missing and ran back into the home to rescue him.
Elizabeth and Nathaniel never made it out of the house. Officials later found the mother with her son in her arms in an upstairs bedroom, but suspect smoke may have barred their escape.
ABC reports that six other residents, among which were four minors, escaped the fire and were in stable condition.
Investigators are still investigating what caused the fire.
