Investigators said the fire started in a basement stairway of the home on the 3100 block of Concord Lane.
As investigators search for a cause of a fire that tore through a Wadsworth home Wednesday afternoon, police are looking into why two young children were in the home by themselves.
"We could hear these kids screaming," one neighbor said. "They were just screaming, like, they can't breathe, they think they were going to die, 'Help us.'"
The two siblings -- an 8-year-old boy and a 9-year-old girl -- were found within two feet of each other in a bedroom of the house on the 3100 block of Concord Lane. Their limp, lifeless bodies were removed from the home.
"Our fire crews did an excellent job to revive them," said Waukegan Fire Chief Dan Young.
A 5-year-old who also lives in the home was with a neighbor.
Officials briefly shut down a fairway on the Midlane golf course to accommodate the Flight for Life helicopter, the Lake County News Sun reported.
Investigators said the fire started in a basement stairway of the home but haven't yet determined exactly how it began.
Neighbors said they're relieved that the two youngsters are alive and using it as a life lesson for their own children.
