A Dorchester man was convicted of voluntary manslaughter today for stabbing 26-year-old Adam Rich to death in a brawl at a South Boston tavern, Suffolk County District Attorney Daniel F. Conley announced.

BERNARD PISCOPO (D.O.B. 3/4/69) will be sentenced tomorrow at 10:00 in courtroom 917 of Suffolk Superior Court. Saying “the likelihood of a jail sentence in this case is quite great,” Judge Linda Giles ordered Piscopo’s bail revoked. He was handcuffed in court and will be held in the custody of the Suffolk County Sheriff’s Department tonight.

Piscopo was indicted for second-degree murder in connection with Rich’s death; voluntary manslaughter was a lesser included offense that carries up to 20 years in state prison. Piscopo was also charged with another stabbing during the same incident that left a 24-year-old Malden man injured; he was acquitted of that stabbing.

During two full weeks of trial, Assistant District Attorney Holly Broadbent introduced evidence and testimony showing that the victim and another man became embroiled in a fistfight at The 6 House on West Broadway in the early morning hours of June 17, 2007. The evidence showed that others present intervened in that melee, including Piscopo and the surviving victim.

Rich was escorted from the bar but soon returned and struck Piscopo. The evidence proved that Piscopo produced a knife and stabbed Rich seven times in the back, chest, stomach, legs, and hand before fleeing through the bar’s back door. Rich was pronounced dead of his injuries at the Boston Medical Center a short time later.

Piscopo’s conviction comes after three full days of jury deliberations. On Friday, jurors sent Giles a note indicating that they were deadlocked; Giles read them a legal instruction urging them to try again to reach a unanimous decision.

Nicole Crosta was the victim-witness advocate assigned to the case. Piscopo was represented by attorney Robert George.
