WASHINGTON CROSSING, Pa.—Pennsylvania authorities drew on 100 people, drones and cadaver dogs Monday in their search for two missing children whose family’s car was swept away in flash flooding that ravaged the East Coast over the weekend. Other parts of the country endured threateningly high temperatures and severe air pollution from Canadian wildfires.
In eastern Pennsylvania, authorities described Monday’s search for missing Matilda Sheils, 2, and her 9-month-old brother Conrad Sheils as a “massive undertaking” along a creek that drains into the Delaware River. The children are members of a Charleston, South Carolina, family that was visiting relatives and friends when they got caught in a flash flood Saturday.
