A massive search is underway in suburban Philadelphia for a missing 9-month-old boy and his 2-year-old sister who were swept away in a flash flood while driving to a barbecue with their family. The search effort involves 100 crew members and numerous drones along the creek that drains into the Delaware River. The children are part of a South Carolina family visiting relatives when they got caught in the floodwaters. The mother and two other children were swept away and later found dead, while the father and another child were able to reach safety.
