The bizarre crime involves smugglers, gangsters, suspicious deaths, and a mystery that remains unsolved to this day.

The Shark Vomits Up Evidence

A fisherman caught a small shark off Coogee Beach, which was immediately swallowed by a 12-foot tiger shark. The larger shark was taken to the Coogee aquarium as an attraction, especially timely since sharks had recently killed three men in the area. On April 25th, Anzac Day, the shark began acting strangely and eventually vomited up a human arm in front of spectators, setting off a murder investigation.
