Three teens frantically used their cellphones to call for help from a sinking van after their troubled mother drove them into a river, their father said Thursday. Ultimately, a passer-by helped all four escape from the cold Delaware River in Florence Township after one sibling kicked out a window. About the same time, township resident Darnell Taylor said he and his wife were driving by the boat ramp when he noticed the partially submerged van in the river. Smith expressed gratitude for Taylor's help in saving the family and noted he's received a lot of support from church and neighborhood groups.
