Doctors are still trying to determine what caused three young children to become sick inside their Hazelwood home.
Authorities say the children's babysitter called 9-1-1 Thursday afternoon when she had trouble waking the children, ages two, three and four. Firefighters pulled the children from the home on Tamma Lane and rushed them to DePaul Hospital.
Just what made them sick is still a mystery. Firefighters checked the home for carbon monoxide leaks, but found none. Initial toxicology tests also gave no clues.
The children were later airlifted to Cardinal Glennon Children's Hospital for more extensive testing. Hazelwood police say they're being told the children are expected to recover.
