Authorities are investigating after a gun was found at Stonehill College following an Oct. 11 shooting incident that was initially reported as a “workplace accident,” according to an Easton police report obtained by the Globe.

Dean Tupper, 57, claimed he was attempting to make a homemade bullet by molding lead to the top of a charge when the charge exploded, causing the lead to shoot off, and strike his co-worker Dave Pigeon, who was walking by, according to Sergeant Darren Mangott, who wrote the report.

Pigeon was found at his desk, the police report states, and authorities observed a blood stain on the floor nearby, but said no blood stains were found on the floor close to where Tupper said he was working.


Tupper was shaking, slouching, avoiding eye contact, and mumbling his short answers to their questions, according to police.

“Mr. Tupper’s body language and speech were consistent with a person who was not being truthful,” Mangott wrote in the report.

Pigeon told police that he was sitting at his desk when “felt a pain in his right knee.” He then began bleeding.

According to the police, Pigeon “does not know what happened,” and does not remember hearing a loud bang. Before police called emergency medical services, Pigeon reportedly told them Tupper had apologized.

Police returned to the school’s campus that afternoon after Lieutenant David Bamford of the Stonehill College Police Department informed Mangott that a K-9 unit discovered a gun in a grassy area close to the building where the shooting occurred.


The gun, which had a magazine inserted but no ammunition, had a legible serial number. The police did not name the gun’s owner.

In a message on Nov. 28 to the Stonehill community about the shooting, the school stated that it had terminated the employee who “brought the unauthorized firearm to the campus.” The school did not say the employee terminated was Tupper.

The incident, which occurred in the plumber’s shop of the school’s Clock Farm, across the street from the main campus, was first reported more than six weeks after it happened, drawing criticism to the school for withholding details.

In the Nov. 28 message, the school acknowledged that officials should have followed up with the community to provide additional details about the incident after the initial investigation concluded.

The Clock Farm houses facilities management offices and workshops, according to a history of the property posted on the school’s website.
