LOWELL – A fourth person has been charged in connection with the July 7 murder of Quintin Koehler, 22, of Billerica, and all four men were indicted today by a Middlesex Grand Jury, Middlesex District Attorney Gerry Leone informed the public today.

A Middlesex Grand Jury indicted the following defendants:

• Adam Bradley, 27, of Lynn, was indicted on charges of murder, attempted armed robbery, home invasion, and possession of a firearm.

• Peter Bin, 25, of Peabody, was indicted on charges of murder, attempted armed robbery, home invasion, and possession of a firearm.

• Jason Estabrook, 28, of Lynn, was indicted on charges of murder, home invasion, and attempted armed robbery.

• Gabriel Arias, 20, of Lynn, was indicted on charges of misleading a criminal proceeding.

An arraignment date in Middlesex Superior Court has not yet been set.

The four defendants are accused of shooting Koehler during an attempt to rob the victim while breaking into his home inBillerica.

Bin was arrested October 26 and has been held without bail following his arraignment in Lowell District Court.   Estabrook and Arias were arraigned September 27 in Lowell District Court.  Lowell District Court Judge Thomas Brennan ordered Estabrook held without bail.  Judge Brennan ordered Arias held on $20,000 cash bail.  Arias was also held on a probation warrant from a case out of Lynn.  Bradley has been held on unrelated charges out of Essex County.

According to authorities, on July 7 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, evidencing a gunshot wound.  The victim was transported to Lahey Clinic where he was pronounced dead.  The Office of the Chief Medical Examiner determined the cause of death to be a gunshot wound to the head and the manner of death to be homicide.

It is alleged that Bradley and co-defendants were looking for a person to rob and together agreed to rob the victim.  Bradley, Estabrook, Bin, Arias and others traveled from Lynn to Billerica in the early morning of July 7 with the intent to rob the victim.  Authorities believe the home was targeted because the defendants believed marijuana and money would be present at the home.  The victim and a witness heard the defendant and others in the home and discovered Bradley, Estabrook, and Bin in the kitchen where an assault ensued.  It is alleged that gunshots were fired, hitting the victim in the head.  The suspects then fled the scene.

Authorities allege that Arias misled investigators during the investigation by providing false information to the police.

These charges are allegations and the defendants are presumed innocent until proven guilty.

The case is being investigated by Billerica Police and State Police assigned to the Middlesex District Attorney’s Office.

The Assistant District Attorney assigned to the case is Cara Krysil.  The Victim Witness Advocate is Kathleen Keefe.
