A suspect who authorities say is a principal defendant in a shooting that killed two women and a man in Boston four years ago is set to be arraigned on Monday.
Keron Pierre, formerly of Mattapan, was returned to Boston from Trinidad on Friday and arrested. He's set to appear in Suffolk Superior Court.
Pierre is accused of fleeing Massachusetts days after Anthony Peoples, 19, and Shacora Gaines and Chantal Palmer, both 20, were fatally shot in a car outside a party in Boston's Dorchester neighborhood in March 2009.
Pierre, 27, was arrested in Trinidad on unrelated charges in 2010, Suffolk County District Attorney Daniel F. Conley said on Sunday. Pierre abandoned a challenge to extradition and U.S. marshals escorted him to Logan Airport where he was arrested, Conley said.
Pierre faces charges of first-degree murder, armed assault and firearms offenses. It was not known Sunday if he's represented by a lawyer.
"Three families placed their trust in us to see their loved ones' killer held accountable," Conley said. "Today we're one step closer to that goal, and today this defendant knows what others have already learned: We will find you wherever you run. And we will not rest until justice is done."
Authorities say Pierre and the three victims spoke outside the party at about 4 a.m. on March 29, 2009, and that the conversation escalated into an argument. An altercation prompted Pierre to open fire on the victims as they sat in the car, police say.
Another defendant, Nigel A. Nichols, 27, is in custody as an accessory after the fact. Prosecutors say he drove Pierre from the scene following the shootings.
Nichols, of Brockton, pleaded not guilty in January 2010.
