Two more victims of the doomed cruise ship Costa Concordia were discovered by divers over the weekend, both women, bringing the total number of casualties to 13. Sunday's discovery was found towards the rear of the submerged ship and "wearing a life vest," according to an AP report. That lowers the number of known missing to 20, though Franco Gabrielli, the Italian official overseeing the recovery effort, cautioned reporters today that there "could have been X persons who we don’t know about who were inside, who were clandestine.” The victim remains unidentified, though Gabrielli suggested she may have been a Hungarian woman who frantically dialed emergency services after the accident, and who was never heard from since. 

In an attempt at helping the 3000-plus survivors cope in the aftermath of the disaster, Carnival, the parent company of Costa Cruises, has been calling up passengers daily and "asking if they are suffering nightmares or sleepless night," The Telegraph reports. Costa, who has already offered a full refund to all passengers, has further pledged an additional 30 percent discount on all future cruises:

A spokesman for Costa Cruises said: "The company is trying to do everything they can for those passengers directly affected.

"The company is not only going to refund everybody but they will offer a 30 per cent discount on future cruises if they want to stay loyal to the company."

Somehow the deal is doing little to assuage survivors, over 100 of whom have already joined a class action set to be filed in Miami this week. Each is seeking damages in the vast range of $150,000 to $1.5 million. Meanwhile, Captain Francesco Schettino remains under house arrest during on ongoing investigation into his activities leading up to and following the accident. Schettino stands accused of suspected manslaughter, causing a shipwreck and abandoning the ship. He denies the charges, though newly surfaced audio evidence of Coast Guard officials demanding he get back on board the sinking ship won't do much to bolster his defense.
