WINTHROP, July 3, 2016–Two men are in custody and a third is in critical but stable condition after a physical confrontation at a Winthrop party ended in an overnight shooting, Winthrop Police Chief Terence Delehanty and Suffolk County District Attorney Daniel F. Conley said.

ANDREW GUILFOYLE (D.O.B. 6/3/85), the resident of the Winthrop home, and JARED DAMELIO (D.O.B. 2/25/88), a partygoer, are both charged with assault and battery with a dangerous weapon and are expected to be arraigned in East Boston Municipal Court on Tuesday.

The victim, a 27-year-old Stoneham man, is being treated after surgery at Massachusetts General Hospital.  The preliminary evidence gathered by Winthrop and State police suggests that this man had been involved in a fistfight at the 233 Revere St. party late last night.  The man left the party and returned with others shortly after midnight. He and others in his group were unarmed.

When a second fight broke out, Damelio allegedly struck the victim in the head with a baton and encouraged Guilfoyle to “get the gun.”  Guilfoyle at this point retrieved a rifle, which he lawfully owned. Guilfoyle allegedly fired the rifle once at the victim, striking him in the upper abdomen.

Responding emergency medical technicians transported the victim to MGH with life-threatening injuries. Winthrop Police recovered the rifle at the scene. Guilfoyle allegedly admitted owning and using during the conflict.

In light of the seriousness of the victim’s injuries, Winthrop Police notified the Suffolk County State Police Detective Unit, which has jurisdiction over death investigations in Chelsea, Revere, Winthrop, and parts of Boston. Because the victim is now expected to survive, Suffolk SPDU and additional State Police assets are assisting in the investigation as it is led by Winthrop detectives.
