Jonathan Amerault, 25, a white male, was a Keene, New Hampshire resident who was killed on September 20, 2020. According to investigators and court records, after discovering messages between his wife and Amerault, Armando Barron used his wife Britany's phone to lure Amerault to a park near the Massachusetts border on the night of September 19. There, Barron beat Amerault and tried to force Britany to shoot him.
When she refused, Barron shot Amerault himself in Rindge, New Hampshire, inside Amerault's car. Barron then compelled Britany, under threats and violence, to help move and hide the body. The couple drove north to a remote campsite in Coos County near Errol, where Britany—acting under duress—was forced to behead Amerault and help conceal his remains and belongings.
Authorities tied the killing to the sequence of events that began in Rindge and ended deep in New Hampshire's North Country. Reports described the scene near Errol as a remote campsite area where Amerault's remains were hidden and items were burned or buried, details that later became central to the prosecution's narrative at trial.
Armando Barron was arrested and ultimately tried in Cheshire County. On May 26, 2022, a jury found him guilty of first-degree murder and related charges; the following day, a judge sentenced him to life in prison without the possibility of parole, plus additional consecutive terms. In April 2025, the New Hampshire Supreme Court rejected Barron's appeal, leaving the conviction and sentence in place.
Britany Barron, who cooperated with investigators and testified about the threats and abuse she endured, pleaded guilty in August 2021 to three counts of falsifying physical evidence. She was sentenced that October to three and a half to seven years, with two years suspended, and was later granted parole in 2022. Court filings and subsequent reports indicate prosecutors continued to examine facets of the case in 2024, even after the convictions and sentencing.
