Months before two Boston policemen went against orders and undertook a high-speed chase on Morrissey Boulevard that ended in the deaths of three teenagers, one of the cops involved improperly discharged a BPD firearm in his Hyde Park apartment, narrowly missing a sleeping neighbor.

Yet the politically connected officer, Triston Champagnie remained on the job. And he seems to have thus far avoided being disciplined for the shooting, after a meeting between Internal Affairs (IA) cops and Police Commissioner Michael Cox, a contemporary of his father, Det. Sgt. Patrick Champagnie.

A notation in official BPD records says that last October, months after the deaths of the three teenagers, disciplinary action for the earlier shooting incident was placed “on hold”:

“Per GF (green folder) Mtg w/Commissioner Cox, this case discipline is still on hold.”

It also notes, “Discipline Pending Green Folder Mtg. Oct. 10, 2024 Days/hrs suspended: O”

A department spokesman said the phrase “green folder” refers to preliminary findings in an IA investigation.

Six months after Champagnie improperly discharged his departmental firearm, as the investigation dragged on, the three teenagers died following a chase by Champagnie and fellow Officer Matthew Farley on Jan. 4, 2024.

According to a report in the Boston Globe, the cops were ordered to break off the dangerous pursuit. A supervisor radioed them, “Okay, just to confirm, we have nobody pursuing that motor vehicle. Is that correct?”

“Correct,” Champagnie said. “No pursuing.”

But the transmissions from Champagnie continued, monitoring the youths’ vehicle until it crashed, after having attained speeds of up to 106 m.p.h., according to the State Police.

Thrown from the vehicle and killed were Troy Winslow, age 15, Immanuel A. Brooks, 14, and Kevin Lenes-Davila, age 17.

The BPD internal affairs investigation into the three deaths remains open. The gun violations against Champagnie have been “sustained” by what is called the Firearm Discharge Investigative Team. That finding triggered an IA investigation which seems to have resulted in no disciplinary action.

The shooting occurred at Champagnie’s apartment on Dana Avenue in Hyde Park on June 14, 2023. Another BPD officer, identified as Eric MacPherson, was also present although “he was in the shower at the time of the discharge.”

So as his pal was taking a shower, Champagnie was for some reason handling his buddy’s gun – a loaded Glock 43X.

“Officer Champagnie accidentally discharged one round, which went through the wall and into the neighboring apartment. The round traveled through the headboard where (neighbor) Ryan Kluska was sleeping, through the comforter, and another wall before striking the stove and stopping.”

So did Officer Champagnie then follow BPD procedure and notify an Operations Division Supervisor? He did not.

“Instead (he) notified his father, Sgt. Det. Champagnie, who notified District 18, who notified Operations.”

Daddy Champagnie is a big shot in the BPD. He made $368,222.47 last year, according to city payroll records.

Triston, despite his checkered career, including at least two disputed traffic stops in addition to the shooting in Hyde Park and the triple fatality in Dorchester, was paid $111,387.05 last year.

One brother, also named Patrick, is also on the job, collecting $231,979.64 last year. Another brother, Preston, made $70,560.16 from the BPD last year.

The IA report on the Hyde Park firearms discharge was produced by a different sergeant detective, Daniel Conway. He made $333,069.33 last year.

By coincidence, there are as many Conways on the BPD payroll as Champagnies. In addition to crack sleuth Dan, Officer John A. Conway made $352,667 last year working in “headquarters dispatch.” A John D. Conway grabbed $310,560,41 in “mobile operations.” And Police Officer Kendra Conway made $165,687.34 in 2024.

The incident involving the firearm and the fellow officer in the shower occurred in June 2023. Yet the incident report is numbered IAD2024-0015, indicating the probe wasn’t officially opened until early last year, probably after the three teenagers were killed on Morrissey Boulevard.

On Wednesday, I asked the BPD about the apparent six-month delay in officially opening an investigation. A BPD spokesman said that the 2023 Firearms Discharge Investigative Team had to first “sustain” the charges, before the IA investigation could begin in 2024.

In the interim between the two investigations, Champagnie’s probationary period as a police officer ended, which meant that he had much greater civil-service and union protection from being fired. How convenient.

I also formally inquired if Commissioner Cox is a “personal friend of Champagnie’s father.”

There was no answer.

Doesn’t the City of Boston now have a civilian review board of some kind? Surely this is the sort of matter that should rise to the level of their attention?

What about the Boston City Council? Do they still have a Public Safety Committee? At one time, I believe the chairman was Tania Fernandes Anderson.

Does she have time to probe this matter before May 5, when she is scheduled to plead guilty to multiple felonies committed in City Hall?

On Monday, a lawyer for one of the aggrieved civilians seeking BPD internal-affairs documents on Triston Champagnie expressed his frustration about the Boston cops’ reluctance to comply with court orders (not to mention public-records demands).

“They flat out refused to comply with the court’s orders,” the lawyer said. “If we don’t (follow) court orders, we get held in contempt.”

Forget it Jake, it’s the BPD.

In my official inquiry to the BPD, I had one final question:

“Does the Commissioner regret not taking action against Champagnie in 2023 that might have kept him off Morrissey Blvd. on the night when the three youths were killed? Would he like to issue a public statement of apology to the families of the dead youths for his apparent lapse in judgment?”

No answer.

It’s enough to make you want to take a shower. But not in Officer Champagnie’s apartment. That would be almost as dangerous as driving around on Morrissey Boulevard.
