A Suffolk County Grand Jury has indicted Johnnie Bonnie, 22, of Jamaica Plain, in the June killing of Evens Archer.
Archer, 17, was gunned down at a South End party on Castle Court.
Prosecutors aim to prove Bonnie was the man who fired one shot into the back of Archer’s head. It was three weeks before Archer, a Dorchester resident, died from his injuries, prosecutors said in a statement.
Grand jurors handed down the indictment on Friday. Prosecutors said video and witness statements finger Bonnie as the shooter. Bonnie is in jail on $15,000 bail on a separate charge of having an illegal firearm, the Suffolk County District Attorney’s office said.
Friends of Archer paid tribute to him with a YouTube video and the Twitter hashtag #LongLiveEA.
