On Friday, April 15, 1994, in San Diego, California, surfers noticed a shape bobbing in the water that seagulls were perched on. Upon inspection, what the surfers thought may have been a kelp outgrowth was actually the body of Michelle von Emster, completely naked aside from a brass bracelet and two rings on her left hand. The ME concluded that Michelle was the victim of a shark attack, but the experts disagreed.
