NANTUCKET (CBS) -- A Nantucket man out fishing Sunday on Sconset Beach ended up hooking into something a bit larger. Elliot Sudal caught a brown shark, about seven feet long and 200 pounds. Sudal was bluefishing but soon noticed there was something else swimming offshore. As he was reeling in the bluefish, they were getting bitten in half by something big.
