The eerie images show investigators swimming through darkened hallways and stairwells, picking their way through water-logged books on the submerged deck. They also find what appear to be shoes left behind when the doomed ship capsized two and a half years ago. Computer terminals at a reception desk remain in place, as does a vase holding flowers on the countertop.
Another shot shows a tangle of pipes from within the 290-metre ship that ran aground off the coast of Italy on Jan. 13, 2012. The disaster killed 32 people. Officials announced on Thursday that an operation to refloat the ship should be complete within 10 days.
