Three items from the weekend that each carry a legal question worth a paragraph: an off-duty officer’s arrest on Cape Cod, a juvenile charged after the FBI flagged a game chat, and a strike vote at the state’s largest safety-net hospital.
Sandwich officer arrested for OUI after crash into a resident’s yard
At about 9:30 p.m. Friday, a vehicle drove through the bushes of a home on Grand Oak Road in the Forestdale section of Sandwich and struck a parked car. The driver was Matthew Cotter, 44, an off-duty Sandwich police officer. Responding Sandwich officers suspected impairment, and State Police arrested him after field sobriety tests and took him to the Bourne barracks. He is charged with operating under the influence of liquor, negligent operation, a marked lanes violation and operating an unregistered vehicle. He was uninjured and has been placed on administrative leave. The department said its members “hold each other and themselves to the highest standards.” A relative of Cotter’s who arrived at the scene is under investigation for shouting obscenities at and allegedly shoving a news videographer.
The legal footnote is the POST Commission. Since 2021, every Massachusetts officer is certified by the Peace Officer Standards and Training Commission, and a department must report an arrest to it. A first-offense OUI conviction, or a continuance without a finding, is not automatically decertifying, but it is a disciplinary matter the commission tracks, and a sustained finding goes on the public disciplinary record. The department’s own investigation runs on a separate track from the criminal case, and the outcome of one does not bind the other.
Update, September 12. POST Commission records show Cotter has four prior sustained disciplinary matters, including a September 2025 untruthfulness finding resolved by a suspension held in abeyance for one year. We report the record in the officer’s POST Commission history.
Raynham juvenile charged after FBI flags game-chat threats
The FBI notified Raynham police Friday that a user on an online gaming platform had posted two statements in a game text chat, one threatening to shoot up a school and one threatening to bomb one. The platform flagged the messages. Police identified a 17-year-old Raynham resident, found the threats were not credible, and located no weapons; the juvenile had no access to any. He was arrested and charged with making a false bomb threat and will be arraigned in Taunton Juvenile Court. The Bridgewater-Raynham schools increased police presence Friday as a precaution. Chief LaPlante: “These types of threats are taken extremely seriously, regardless of where or how they are made.”
Two points on the law. First, the charge is the threat, not the plan. Under chapter 269, section 14, communicating a bomb threat is a crime whether or not any device exists, and the absence of weapons is why the charge is false bomb threat rather than something worse. Second, at 17 the case belongs in Juvenile Court under the 2013 law raising the age of juvenile jurisdiction to 18, with one exception that does not apply here: murder charges against anyone 14 or older go to adult court, as we explained in the Acton case. A juvenile adjudication is not a conviction, and the record is not public.
Boston Medical Center nurses authorize a three-day strike
Nearly 2,000 registered and licensed practical nurses at Boston Medical Center’s main campus, along with about 70 at the affiliated Brockton Behavioral Health Center, voted to authorize a three-day strike, with nearly 90 percent of those voting in favor. The nurses are represented by 1199SEIU and have been bargaining for more than six months. An authorization vote is not a strike. Federal law requires a union at a health care institution to give ten days’ written notice before striking, and none has been issued. The next bargaining session is September 25.
The ten-day rule is specific to hospitals and exists so that patients can be transferred and staffing arranged. A three-day strike is the pattern the Massachusetts Nurses Association has used at other hospitals, and hospitals typically respond by contracting replacement nurses for a minimum block, often five days, which is why a three-day walkout can turn into a five-day lockout. Nothing about the vote changes patient care this week.
Sandwich arrest from the Sandwich Police Department, Cape News, NBC Boston and WHDH, September 12, 2026. Raynham arrest from the Raynham Police Department’s release, September 11, 2026. Strike vote from WHDH and WCVB, September 12, 2026. Matthew Cotter and the Raynham juvenile are presumed innocent. General information about Massachusetts law, not legal advice.
