Checking out the tip from a retired Parsippany police officer of weapons dumped into the Passaic River, officers found the guns Wednesday night in a box on the riverbank behind Lucky Steak Plate on Maple Avenue off River Road.
Members of the Fair Lawn Rescue Squad and Fire Co. 1 put boats in the river, Sgt. Brian Metzler said, but didn't find any additional firearms.
The Bergen County Prosecutor's Office was notified.
Makes and models were temporarily withheld while an investigation into the source of the guns continued.
