Greece ? Investigators using a remote-controlled submarine found a sunken Greek cruise ship’s data recorder and planned to bring it to the surface Friday, authorities said.

The Merchant Marine Ministry said the recorder could reveal details of the sinking of the Sea Diamond, information they hope to use in the prosecution of crew members.

Two French tourists remain missing from the ship, which struck well-marked rocks April 5 and sank off the main port of the Greek holiday island of Santorini. Nearly 1,600 people were rescued, including hundreds of Americans and groups from Canada, Britain, Australia, France and Spain.

The ministry and the cruise line have blamed the sinking on human error. The ship’s captain and five other crew members have been charged with negligence and are expected to testify next week in the ongoing probe.
