Two Brockton brothers were sentenced to four months in federal prison each on Monday for staging a bank robbery that netted $197,146 from a West Roxbury credit union where one of them worked as a teller. Jenel Flounoury, 30, and Justin Flounoury, 34, were also ordered to serve three years of supervised release and to jointly repay the full amount they stole.
U.S. District Court Judge Allison D. Burroughs handed down the sentences in Boston federal court, according to the U.S. Department of Justice. The case stemmed from a September 2024 incident at Energy Credit Union, a $129 million asset institution with a branch at 156 Spring Street in West Roxbury, as detailed by the Credit Union Times. As Boston 25 News reported, authorities said Jenel and Justin Flounoury stole the money from the credit union on September 24, 2024.
An Inside Job From the Start
According to court documents cited by Boston 25 News, Jenel Flounoury arranged for a large cash deposit to be stored in a vault section he could access, then set up a plan for his brother to pass him a note demanding money while he worked his teller window. On the afternoon of the heist, Justin left his job in South Boston early and was driven to West Roxbury wearing a disguise that included a hat, dark clothing, sunglasses, and a face mask, per the Department of Justice.
Once inside, Justin presented his brother a note reading “Hand it Over” at the teller station. Rather than following standard protocol, Jenel bypassed his own cash drawer and went directly to the vault, loading nearly $200,000 into a bag he retrieved himself before handing it off to his brother, court documents say.
Bank Managers Spotted the Red Flags Fast
The Suffolk County District Attorney's Office said Energy Credit Union's Chief Financial Officer flagged the incident as suspicious almost immediately, noting that tellers are trained to comply with robbery demands using only the cash available in their own drawers rather than accessing the main vault. Handing over far more cash than the note demanded, while skipping his assigned station entirely, was what first tipped off management that the robbery had been staged.
The case also carried an uncomfortable staffing backstory. The Suffolk County District Attorney's Office noted that Jenel Flounoury had been fired by Energy Credit Union in May 2023 for violating company policy, only to be rehired in August 2024 — just one month before the staged theft took place.
Burned Clothes and Marked Bills Sealed the Case
Investigators moved quickly. Police executed a search warrant at the brothers' home hours after the robbery and recovered more than $160,000 in cash, with the Credit Union Times putting the exact figure at $160,275 — leaving roughly $36,871 of the stolen funds unaccounted for. Energy Credit Union employees had recorded the serial numbers of ten $100 bills known to be in the vault before the robbery, and investigators later recovered those same marked bills during their search.
Surveillance video also captured the brothers burning dark-colored clothing matching the robber's outfit in a grill at their residence, and officers later recovered burnt clothing remnants, according to the Department of Justice. Cell site location information placed Justin Flounoury's phone within a quarter mile of the credit union during the robbery, per court documents, and that same location data reportedly tracked him back to the shared residence shortly after the incident.
Brothers Turned on Each Other Before Pleading Guilty
The Flounourys were indicted by a federal grand jury in January 2025 on felony charges of credit union larceny and conspiracy. The case grew contentious well before sentencing: in April 2026, both brothers filed separate pretrial motions to sever their trial, according to court records on CaseMine. Justin claimed Jenel had worked with an unknown third party, while Jenel claimed Justin was the sole instigator of the scheme.
That antagonistic defense strategy never reached trial. In July 2026, federal prosecutors agreed to drop the substantive larceny count in exchange for guilty pleas to conspiracy from both brothers, a deal the Credit Union Times reported significantly narrowed their legal exposure. Credit union larceny carries up to 10 years in prison, compared to a five-year statutory maximum for conspiracy under 18 U.S.C. § 371, which also allows fines of up to $250,000, per the Department of Justice.
In the end, Judge Burroughs imposed four months in prison for each brother, well below the statutory ceiling, along with three years of supervised release and joint responsibility for repaying the full $197,146 taken from the vault.
