The captain of the Costa Concordia, Francesco Schettino, has been placed under arrest and may be facing manslaughter charges stemming from the six deaths authorities now say he caused.

Italy’s Corriere della Sera newspaper reports that the captain executed a swing-by maneuver near the island of Giglio so the ship’s head waiter could wave to family on shore. It is not known if the waiter asked for the maneuver, or if the captain intended to surprise him.

The waiter’s sister had posted a Facebook status:

Which translates to:

‘Shortly the “Concordia di Costa Cociere” will be close. A salute to my brother, who will finally disembark for a holiday in Savona.’

However, apparently the captain misjudged the maneuver and crashed the ship into the rocks near the island. More than 4,000 people were evacuated in the night. Six have been found dead so far; fifteen are still missing.
