On July 15, 2023, a family from Charleston, South Carolina, was caught in a sudden flash flood on Route 532 in Washington Crossing, Pennsylvania, after about seven inches of rain fell in roughly 45 minutes. Nine-month-old Conrad Shiels was swept away along with his two-year-old sister Matilda Mattie Shiels and their mother, Katheryn Seley; the father and a four-year-old child reached safety and the grandmother survived after being swept away.

An extensive search involving hundreds of volunteers and multiple agencies used drones, boats, K9 teams, divers and sonar to search land and waterways including the Delaware River. Mattie’s body was recovered several days later more than 30 miles from where she was last seen, and Katheryn Seley and four other victims of the flood were also recovered. Officials ultimately announced they had exhausted available means and concluded the active search for Conrad.

If anyone was in the Washington Crossing area on July 15 or saw conditions on Route 532 that day, please come forward with information that might help the family.
