NEW BOSTON – The New Hampshire Attorney General’s Office, New Hampshire State Police and New Boston Police responded to a fatal officer-involved shooting at the New Boston Space Force Station Friday.

The incident occurred on an access road to the New Boston Space Force Station located off of 317 Chestnut Hill Road.

The AG’s office in an update Sunday said the man who was killed was 33 and from Massachusetts. Officials are withholding the man’s name pending notification of family members.

An autopsy conducted by Deputy Chief Medical Examiner Dr. Mitchell Weinberg determined that the man’s cause of death was a single gunshot wound, and his manner of death is homicide. As used by the Office of the Chief Medical Examiner, homicide is defined as the killing of one person by another.

The update also stated the incident involved a New Boston police officer and a member of a contracted security agency.

According to sources, a man approached the armed guards at the entrance gate of the secure facility on Chestnut Hill Road and engaged in a conversation with the personnel.

The man allegedly exited his vehicle with a weapon or weapons, and was fatally shot at the entrance. New Boston, Amherst and Bedford Fire and EMS responded, but the shooting victim was deceased. According to radio dispatch, one person was going to be medically evaluated by medics, but it is not known if that was an employee of the base.

The vehicle contained a gas can and propane tank which could be seen on the ground next to the vehicle where investigators were working. Initially, the presence of the gas can and propane tank concerned responders, and an evaluation was done to deem that they were not a danger.

New Boston Police were stationed on Chestnut Hill Road blocking the entrance to the facility Saturday morning. New Hampshire State Police Major Crime investigators could be seen working in the area of the car, which had Massachusetts plates.

The U.S. Space Station was formerly operated by the U.S. Air Force until the transition to the newly formed Space Force.

The Attorney General’s Office on Saturday said that no officers were physically injured in the incident.
