This the body of Robert Palladino, Johnny’s first victim. Martorano was 24 years old, and Palladino was an ex-con who might have been a witness in a murder case involving a hooker, Barbara Sylvester, who had been murdered in Johnny’s father’s club.”

John Jackson was a bartender at the club, a black man from Cambridge. Johnny caught up with him at dawn and that was the end of another potential witness. Martorano’s hits included at least five blacks, including three on Normandy Street in Roxbury in 1969. He was looking for a black guy who’d beaten up his Mob mentor, Stevie Flemmi. Unfortunately, there were two black teenagers sitting in the car when Johnny arrived on the scene. When police arrived, the girl, shot dead in the head, was still holding a burning cigarette between her fingers. From then now, Johnny was known as “Sickle Cell Anemia” – he was deadly to blacks.

Boston Globe list of Martorano’s victims. Johnny was on the lam from 1978 to 1995, but was finally arrested in Boca Raton. He flipped after Stevie Flemmi admitted he was an informant, and Johnny got to read the FBI 209 reports – in which his old pal Stevie called him a “pimp” and considered framing him for his planned murder of Mafia captain Larry Baione. Once Johnny flipped everyone began turning, as some of the following letters show.

The Government’s Motion For Reduced Sentence
 

The Martoranos, Johnny and Jimmy, were born 11 months apart, and they were in the same class at Milton High. Can you spot them in this photo? Hint: top row. If you guessed that Johnny, with the ducktail, is fourth from the left, you're right. Jimmy is sixth from the right, with one poor guy between them.
