This ought to get your spine tingling if you were terrified of the movie "Jaws."

A 14-foot Great White Shark tagged last year in Cape Cod, is now being tracked this week just off the coast of Boynton Beach.

Katherine, as its named, has traveled at least a hundred miles south since Tuesday and isn't showing signs of stopping.

Earlier this week a diver near Vero Beach had a close encounter with a great white that swam aggressively around him...although it's not confirmed if that shark was Katherine.
