The report, not yet confirmed by Italy's Civil Protection Authority, follows the authority's Wednesday announcement that all accessible areas of the wreck had been searched, along with the surrounding seabed. This had yielded 'the remains of a body and other bones' that were to undergo DNA testing.
The results of the tests were to determine whether the search for the two missing bodies could be considered definitively concluded or whether the effort would need to continue later, when Costa Concordia is out of the water.
Besides Trecarichi, a passenger from Sicily, crew member Russel Rebello of India was missing.
Officials had resumed their search for remains of the January 2012 grounding, which left 32 people dead, after the wreck was uprighted in a parbuckling operation completed last month.
