The mistery of Mary Celest

The captain's wife was nine months pregnant and started having contractions. Quickly, the other crew took her to an empty room. Few hours after the baby was stillborn and the mother passed away. The captain went mad and killed all the crew and launched the bodies overboard so nobody knew what had happened. Later, the captain put some ammunition in a lifeboat and escaped. He was rowing for two weeks without knowing what direction to take. Some sharks smashed the lifeboat and ate him.
