Air and water craft began searching the river after her car was found abandoned in the middle of the bridge's lower level.
A short time later, a recovery effort was launched.
The upper level has a suicide-prevention fence. The lower level doesn't.
The youngsters were at an annual retreat sponsored by the Newark Catholic Committee on Scouting at Ross Dock picnic area along the river in the Fort Lee section of Palisades Interstate Park.
The NYPD, Port Authority and Palisades Interstate Parkway Police all had boats in the water north of the riverfront park.
Since the upper-level fence was completed, there have been a few jumps from the lower level, as well as from the area on the New York side above the Hudson Hudson Parkway.
