10-year-old boy drowns in New Jersey river, sister lives, and another child is missing

A 10-year-old boy drowned in a rain-swollen river in Passaic, New Jersey, while playing with two siblings in Pulaski Park. His sister survived after he reportedly helped her stay above water, but another 10-year-old girl remains missing as search efforts continue. Heavy rainfall caused the river to rise, complicating rescue operations.
