Mansfield Mystery Update: Town Leaders Say Police Chief Not Fit to Serve as Top Cop

Town leaders say Mansfield Police Chief Ron Sellon is not fit to continue serving as police chief, and the town will now begin "dealing with" Sellon's employment status

The NBC10 Boston Investigators have an update to the Mansfield mystery they've been following for months.

Town leaders now say Ron Sellon is not fit to continue serving as police chief.

As the NBC10 investigators previously reported in April, the town quietly placed their top cop on paid administrative leave almost a year ago, meaning taxpayers were paying nearly $400,000 for two police chief salaries.

We fought for months to get a copy of the town's private investigation. The state eventually sided with us and ordered the Massachusetts town to provide a redacted copy. They sent us the full report just a few minutes before midnight Friday. It detailed many instances of inappropriate work behavior, including fits of rage, angry and threatening text messages, abusive and disrespectful behavior, and damage to police department property.

The town's private investigation also uncovered Nest doorbell video that captured Sellon in a profanity-laced outburst about town leaders outside his home following the town election last May. In the video, you hear loud banging noises and a tirade aimed at residents, the town manager, and the chair of the select board.

In a statement, Sellon responded in part saying he is "heartbroken" by the town's conclusion and said the outburst was due to the emotional and physical stress of being on paid leave for so long. He said he does not agree with the outcome and believes the process to these findings were "unacceptably flawed." And just like he did last month, the chief reiterated that he remains committed to the job.

"I just want to go back to work," he said. "It's everything to me."

The town says it will now begin "dealing with" Chief Sellon's employment status. They didn't put a timetable on what happens next, but the NBC10 Boston Investigators will keep you posted on any new developments.

The Town of Mansfield released a Nest video from a neighbor capturing an outburst by Police Chief Ron Sellon on May 10, 2022.

In an exclusive interview with the NBC10 Investigators last month, Sellon spoke publicly for the first time about the workplace misconduct allegations that landed him on paid administrative leave last year.

“I have done my very level best to resolve this situation and bring it to an amicable close,” Sellon said in July. “And I’m still here waiting. Nobody wants to get paid to sit at home. My goal is to get back to the business of doing what I love.”

Sellon and his attorney provided an excerpt of the private investigation conducted by Matthews & Matthews, LLC on behalf of the town.

According to the report, the firm was hired to probe allegations of “harassing, bullying and unbecoming conduct” by Sellon over the past three years.

When asked to describe the allegations, Sellon responded: “They are not exactly the most flattering thing on the face of the earth. But at the same time, not what I would amount to misconduct.”

At his home in Mansfield, Massachusetts, Ron Sellon sat down for an exclusive interview with the NBC10 Boston Investigators to discuss why he has been on paid administrative leave for months.

As we first reported, the town hired the private investigators last December. Financial records show the town has paid at least $13,000 to date for the investigators to prepare and conduct interviews with a handful of people, including the deputy chief, a lieutenant, a detective, two administrative staffers and Sellon.

Those interviews occurred at beginning of the year, according to invoices. Months later, with the investigation seemingly concluded, taxpayers are continuing to shell out a rate of $388,000 for two police chief salaries.

According to the documents, private investigators had reached their own conclusions at the beginning of May. They sustained a number of allegations against the police chief. Those included:

  • Profanity-laced outbursts
  • Angry and threatening messages to subordinates
  • Abusive and disrespectful behavior
  • Damaging his town cell phone after throwing it in his office
The police chief in Mansfield has mysteriously been on paid administrative leave since last year and taxpayers are shelling out two police chief salaries.

When questioned, Sellon denied having an anger management problem and told us none of his behavior justifies losing his job.

“I’m not a perfect person,” he said at the time. “I think I could’ve obviously handled certain things better. That said, I don’t believe there was anything that couldn’t have been handled with a conversation.”

When asked if he is fit to serve as Mansfield’s top cop, he responded at the time: “I’m absolutely fit to serve as the police chief.”
