Admitted Murderer and 'Hitman' Testifies in Bulger Trial

John Martorano, an admitted murderer, calmly told jurors in the trial of James "Whitey" Bulger about several murders he was involved with, according to media reports about Monday's testimony.

According to WBUR, when asked about several of his victims, including Johnny Jackson, Tony Veranis, and Robert Palladino, Martorano replied about each man, "I shot him."

Martorano told the jury Bulger "broke my heart" when he learned Bulger and Stephen Flemmi, a Bulger associate, were informants for the FBI, according to BostonHerald.com. "The were my partners in crime. They were my best friends," Martorano said, according to the news website.

Martorano admitted to killing 20 people, and he reached a controversial plea agreement that let him out of prison in 2007 after serving 12 years, BostonHerald.com adds.

Despite that, and despite a book he worked on with Howie Carr titled, "Hitman," Martorano told jurors he wasn't a hired killer.

Martorano linked Bulger to some of the murders, including that of Al Notorangeli, according to Boston.com.

Bulger is accused of participating in 19 murders.

Martorano's testimony made several references to Somerville and Somerville's Winter Hill Gang, according to Twitter reports from news outlets covering the trial.

WBUR tweeted: "Martorano describes murdering James Sousa in back of garage in Somerville. Says #bulger came by and helped clean up all the blood."

The Winter Hill Gang's garage, on Marshall Street, has since been converted to a church.

Martorano also talked about a gang war that broke out between Somerville and Charlestown in the 1960s, WBUR tweeted.
