With its human cargo of migrants filling every available space, the battered blue trawler was about halfway from Libya to Italy when its engine cut out in the night.
The vessel wobbled sharply, flooded and capsized. Less than 15 minutes later, it sank into one of the Mediterranean's deepest points, off the coast of Greece. Hundreds of people are thought to have been on board when the boat went down Wednesday, although authorities have no precise figure.
