Very possible.But wasn't the shark caught in the Raritan Bay a Great White ? This conflicts with the fact that only Bull sharks are known to be able to swim in fresh water ( Matawan Creek). So maybe this was actually two sharks. A great white that killed the two swimmers along the coast and a Bull that swam up the creek and did its damage there.
Too much time has passed to really know for sure. Only info is from media reports. Most papers in those days were tabloid-ish, so you have to filter out the garbage. Have to think there was much hype with this one. Like the human remains inside the sharks, are there any pics? Or, is it just" a guy said that he heard" kind of stuff.
