The Court of Cassation annulled without delay the life sentence imposed on the boss of 'Ndrangheta Tommaso Costa for the murder of the merchant Gianluca Congiusta, killed in Siderno in an ambush on May 24 of 2005. However, the Court of Appeals will have to go back to ruling on Costa to determine the punishment of a conviction for Mafia association, drug trafficking and attempted extortion.
The man's attempt to foil an attempted extortion against his father-in-law is the motive for the murder. According to the reconstructions of the DDA the story would intertwine with the rivalries between the Costa and Commisso clans.
