A child fell of a boat into the Delaware River Friday night during a family outing and two men went in after him.
That was around 9 p.m. near the Tacony-Palmyra Bridge, according to the Coast Guard.
One man was found alive and a search by water and by air continued late Friday for the other two as distraught family members hovered on the shore near at the Frankford Arsenal, awaiting word.
Coast Guard and state police Marine units are using infrared lights to search the water. Philadelphia's police chopper is helping from the air.
