The second defendant charged in Fred Bing’s 2009 homicide pleaded guilty today, Suffolk County District Attorney Daniel F. Conley said.

ABIONA SHARPE (D.O.B. 6/3/89) of Revere pleaded guilty to second-degree murder for the 49-year-old Dorchester man’s shooting death on Wilcock Street on the night of May 13, 2009. He was sentenced to the mandatory life term plus a two-and-a-half-year house of correction sentence for unlawfully possessing the .22 caliber rifle he used that night.

Sharpe’s co-defendant, DAMANTE BURRELL (D.O.B. 9/5/92), pleaded guilty to manslaughter and gun charges two weeks ago in connection with Bing’s homicide. He is serving up to 25 years in state prison.

“No term of years can return Mr. Bing to his family and no proceedings could ever make sense of his death,” Conley said. “We hope, however, that these sentences and the defendants’ admissions of guilt can bring his loved ones and friends some satisfaction that the truth has been found and justice has been done in his name.”

Had the case proceeded to trial, Assistant District Attorney Ian Polumbaum of Conley’s Homicide Unit would have introduced evidence and testimony to prove that Sharpe, Burrell, and two others travelled to Wilcock Street in a minivan at about 10:20 that night. At that moment, Bing and a small group of friends were standing outside talking.

The evidence would have shown that Sharpe was seated in the rear of the vehicle and fired the rifle multiple times at Bing’s group. Burrell fired a 9mm handgun from the front passenger seat, raising himself up through the window and firing over the roof.

Bing’s group scattered at the sound of gunfire, Polumbaum said. No one called 911, but the city’s ShotSpotter system activated and Boston Police responded within minutes. The officers saw no victims at the scene and Bing’s friends thought he had fled.

“His friends thought he had gone home because he had family nearby,” the prosecutor said.

In fact, Bing was found at the end of a driveway off Wilcock Street early the next morning. He had been struck in the foot, thigh, and torso. His body was blocked from view by a vehicle and the porch of a residential building.

Police obtained a description of the van and soon found it parked on nearby Estella Street. The engine was warm and the roof had a gouge from one of the 9mm rounds striking it from right to left. There were shell casings inside the van and caught on a windshield wiper that would later match casings at the Wilcock Street scene.

Police were drawn to an occupied Acura nearby when it backed up, struck another vehicle, and sped away; when they stopped it, it contained Sharpe, Burrell and two other males, including one who was sitting on the keys to the minivan.

A search of Estella Street turned up the handgun and the rifle stashed in an alley. These guns matched shell casings from the van and the crime scene – but investigators could not determine which weapon fired any of the projectiles that struck Bing.

Sharpe was a close friend of 16-year-old Terrence Jacobs, who was murdered in a 2007 incident that began on Wilcock Street and ended nearby. In that case, Jacobs’ assailants beat, kicked, and stabbed him to death; four men were later convicted of his murder and are serving life terms for it.

Bing had no role at all in Jacobs’ death, prosecutors said, and was shot for standing on a street in the area in which the youth had been killed two years earlier.

“That stupid, shameful mindset has left too many innocent people – adults and children both – dead in this city,” Conley said. “It has to stop.”

Catherine Rodriguez was the DA’s assigned victim-witness advocate. Sharpe was represented by attorney Samuel Goldberg.
