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.
Estabrook’s next court date is November 26 for a probable cause hearing. Arias’ next court date is November 27 for compliance hearing. .
“We allege that Bin, in a joint venture with others, including Estabrook, intended to rob the victim during a home invasion where, during a struggle, the victim was shot in the head,” District Attorney Leone said. “This is a disturbing case of drugs fueling an act of gun violence. We intend to hold these men accountable for their actions that took the life of another person.”
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 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 Estabrook, Bin and others broke into the victim’s home in the morning of July 7 with 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 Estabrook, Bin and the other intruders in the kitchen where an assault ensued. It is alleged that the 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.
Bin was arrested in Lynn by the Lynn Police with the assistance of the State Police assigned to the Middlesex District Attorney's Office, the Billerica Police, and the Peabody Police.
