Costa Crociere's crisis coordinator, Roberto Ferranini, received the longest sentence: two years, 10 months. Also convicted were the ship's hotel director (two years, six months), two bridge officers and a helmsman, whose sentences ranged from one year, eight months to one year, 11 months.
All five were convicted of negligence and multiple manslaughter as part of a plea agreement.
The news comes a day after the trial of former Capt. Francesco Schettino was adjourned until September. Schettino, who has had two plea requests rejected, is being tried separately. When his trial resumes, it's expected to last into spring 2014 and could see the testimony of as many as 1,000 witnesses -- many of them survivors of the tragedy.
Schettino was captain of Concordia on January 13, 2012, when the ship struck a large rock off the coast of the Italian island Giglio and sank. Schettino is charged with manslaughter and abandoning ship.
