( CNN ) -- Human remains have been found on the wrecked Costa Concordia , possibly answering what happened to the last two missing people from the cruise liner that struck rocks off Italy 's Giglio Island in 2012 , a spokesman for the head of Italy 's civil protection agency said Thursday . Divers will try to recover the remains , which were found on deck 4 , on Thursday afternoon , the spokesman said . The discovery comes a week after engineers finally righted the ship , which capsized when it hit rocks in the Tyrrhenian Sea in January 2012 , killing 32 of the 4,200 people on board . The toll of 32 includes the two people who were missing but presumed dead : Russel Rebello of India and Maria Grazia Trecarichi of Sicily . Their bodies were long believed to be either trapped beneath or inside the ship . Tragedy transforms island paradise . Rebello , 33 , was a cruise waiter who was last seen helping passengers off the ship . Trecarichi was on the cruise to celebrate her 50th birthday with her 17-year-old daughter , who survived . Authorities say the ship struck the rocks off Giglio Island after the captain , Francesco Schettino , ordered the liner to veer more than four miles off course to salute a former sea captain who had retired on Giglio . How the ship was raised . Schettino faces charges of manslaughter , causing a maritime disaster and abandoning ship with passengers still on board . His trial , which began with preliminary hearings in March , resumed Monday in Grosseto . Schettino argues that he is a hero who saved the lives of more than 4,000 people , not a villain whose negligence led to the deaths of 32 . His defense is trying to prove , among other things , that the ship 's watertight doors did not function properly , and that is the reason the ship sank , leading to all 32 deaths during evacuation . Engineers rotated the ship back to vertical last week after it rested 20 months on its side . The unprecedented maneuver , called parbuckling , exposed a twisted mass of metal dotted with mattresses , passenger luggage and deck chairs on the ship 's previously submerged starboard side . With the Costa Concordia now upright , judges on Wednesday agreed to Schettino 's request for a new examination of the ship . He also wants to walk the judges through the command bridge in a re-creation of the night of the crash . Inside a wrecked cruise ship . Schettino also has told the court that the ship would not have crashed had his helmsman executed his instructions . According to recordings from the ship 's bridge from the vessel 's black box , Schettino directed the helmsman to turn `` hard to starboard '' in English , but the helmsman can be heard asking `` hard to port ? '' The helmsman then turned the ship right instead of left just 13 seconds before it hit the rocks . A maritime expert has testified that those 13 seconds made no difference , saying it takes longer than that to change a ship 's course . But Schettino told the court that if the helmsman `` had not turned the wheel the wrong way , we would have avoided hitting the rocks . '' The trial is expected to last through the fall with a string of witnesses , including passengers , crew members and islanders , who say they saw the captain on shore looking for dry socks before all the passengers had been safely evacuated . The helmsman , Jacob Rusli Bin , and four others were convicted in a plea deal in July for their role in the disaster . A Florence court is considering the validity of those plea bargain agreements . After salvage , island celebrations and relief .
