A female passerby saw the young boy and and girl by the closed daycare center on 100th Street before 11 a.m.

The children were brought to Elmhurst Hospital in good condition.

The 62-year-old driver, Munevar Pastora, was charged with endangerment of the children's welfare and reckless endangerment.
