A Revere man admitted yesterday he helped kill a man who was outside talking with some friends one May night two years ago, the Suffolk County District Attorney's office reports.

Abiona Sharpe, 21, was sentenced to life in prison for second-degree murder for the death of Fred Bing on Wilcock Street. Two weeks ago, Damante Burrell pleaded guilty to manslaughter for his role in Bing's murder over the death of a gang buddy of Sharpe's and Burrell's. Bing, 49, had nothing to do with the violent feud between the two gangs.

Prosecutors say Sharpe and pals got in a minivan to exact revenge for the 2007 stomping death of Terrence Jacobs, the DA's office says: "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."
