WOBURN – Middlesex District Attorney Marian Ryan has announced that two men were sentenced today after being convicted of charges in connection with a home invasion in Billerica on July 7, 2012 during which Quintin Koehler, 22, of Billerica was shot and killed.

Peter Bin, 27, of Peabody, was convicted on December 19 by a jury in Middlesex Superior Court on a charge of first degree felony murder. Bin was sentenced by Middlesex Superior Court Judge Kathe Tuttman to life in prison without parole.

Gabriel Arias, 22, of Lynn, was convicted on December 19 by a jury in Middlesex Superior Court on a charge of misleading a police investigation. Arias was sentenced by Judge Tuttman to five to seven years in state prison.

“The jury’s verdict confirms what our investigation revealed,” said District Attorney Ryan. “Peter Bin was part of a conspiracy to carry out an armed robbery. When the gunmen forced their way into a Billerica home, carrying pistols and wearing masks, two brothers went to investigate and confronted the home invaders. During the struggle that followed, one of the gunmen shot and killed Quintin Koehler. Gabriel Arias tried to thwart the investigation, repeatedly lying to police about his whereabouts and the whereabouts of others.”

“Today our thoughts remain with the family of the victim,” said Billerica Police Chief Daniel Rosa. “I am grateful for the hard work done by our detectives, the Massachusetts State Police, as well as the District Attorney. Billerica is a safer community today because of their fine work.”

According to authorities, on July 7, 2012, at approximately 3:55 a.m., Billerica Police responded to 795 Boston Road for a report of a shooting. Officers discovered the victim, Quintin Koehler, suffering from a gunshot wound. The victim was transported to Lahey Clinic, where he was later pronounced dead.

The Assistant District Attorneys assigned to the case are David Solet and Bethany Stevens. The Victim Witness Advocate is Kathleen Keefe. The case was investigated by Billerica Police and State Police assigned to the Middlesex District Attorney’s Office.
