(ANSA) - Rome, August 23 - Law enforcement officers are seeking the killers of Gaetano Marino, reportedly a member of an organized-crime group, who was shot dead Thursday at a bathing establishment south of Rome. The police are evaluating witness accounts and setting up road blocks in the area in an attempt to find the assassins. The 48-year-old Neapolitan victim was reportedly a boss in the local Camorra mafia, police said. He was killed after walking into the Serenella beach establishment resort in the coastal town of Terracina in front of terrified beach-goers. His two killers arrived on location driving a grey car, and fled immediately after shooting him as many as seven times, according to police witness accounts made by bathers during the course of Thursday evening. Marino was only wearing swimming trunks at the time, having just walked in from the beach. He was accompanied by bodyguards, though the events took place so quickly they were helpless. One of the reported motives could be a power struggle internal to the criminal group known as the "Scissionisti." The killing took place one month after a similar attack in a public square in the coastal town of Nettuno, south of Rome. In that case, assassins shot and killed Modestino Pellino, reportedly another participant of local organized-crime groups, in the back. Terracina is about 80 km southeast of Italy's capital Rome.
