Whitey Bulger trial: Hitman John Martorano implicates former boss in 9 murders A former Boston mob hitman has revealed even more chilling details in his second day of testimony at the trail of his long-time boss, James 'Whitey' Bulger. John 'The Executioner' Martorano, who has admitted to killing 20 people, implicated Bulger in nine murders in less than two days on the witness stand. He is expected to tie the former organized crime kingpin to 11 killings from the 1970s to the early 2000s. Martorano, a 72-year-old who lives a quiet life on a golf course, calmly described brutal executions of associates, cold-blooded betrayals of friends and mistaken hits on victims who weren't mixed up in organized crime at all - just in the wrong place at the wrong time. He admitted to gunning down six people who he hadn't meant to kill - including a bartender Michael Milano who had the misfortune of driving the same kind of car as one of Martorano's targets. The Boston Globe reports Martorano portrayed himself as a 'man of honor' and claimed Monday he 'wasn't a hitman' because he never accepted money for the murders he committed. He said he only killed people to help friends or family members. On Tuesday, though, he admitted that he had been paid $50,000 to murder an Oklahoma businessman in 1981. The money was given to him by, John Callahan, who had been skimming profits off the businessman's Florida company. Martoano said he considered Callahan a good friend. But in 1982, Bulger an the other leaders of Bulger's Winter Hill gang decided that Callahan had to go, too. I felt lousy. But these were my partners,' Martorano testified. We were up to our necks in murders already. If it had to be done, it had to be done. He subsequently went to Miami with an associate, Joe MacDonald, and set up a meeting with the unsuspecting Callahan. When Callahan met Martorano at a van he had rented, Martorano shot Callahan in the back of the head with a handgun wrapped in a towel. Callahan's body was later found in the trunk of an abandoned car at Miami International Airport. Another slaying he described seemed to come right out of a scene from a Martin Scorsese film. Thomas King was a mobster with a rival gang that Bulger and his crew had been forced to work with. Bulger hated King, Martorano testified. 'Him and Tommy couldn't get along, He wanted to get rid of Tommy,' he said. Bulger decided to kill the dangerous King, but knew he would be wary of being lured into a trap. So, he had Martorano and his allies contact King and tell him they needed his help murdering another mobster. They gave king a bulletproof vest and then a gun. The gun had only blanks in it. King got into the front passenger seat of a car he believed would take him to the bar where his target was. Martorano got in the back seat behind him. 'I shot Tommy,' Martorano told the court. Where did I shoot him? In the head. Martorano also said he witnessed Bulger kill mobster Edward Connors in 1975 because he had bragged about helping Bulger's gang murder a rival. Bulger and his partner Stephen 'The Rifle' Flemmi lured Connors into a phone booth in Dorchester. 'They walked to the phone booth and shot Eddie,' Martorano testified. Martorano, is a star witness in the Bulger trial. He has said he had a detailed knowledge of many of the 19 murders Bulger is accused of committing.
