The Tragic Timeline Of Holly Boisvert And Brandon Muff: A Cold Case, A Stabbing, And A 2030 Release Date

The true story of Holly Boisvert and Brandon Muff is not a tale of romance, but a chilling narrative rooted in jealousy, betrayal, and a decades-long cold case that shocked Fort Wayne, Indiana. This deeply disturbing love triangle culminated in a tragedy that took the life of a young woman and saw the perpetrator finally face justice nearly two decades later. As of late 2025, the case remains a prominent fixture in true crime discussions, with the convicted killer currently incarcerated and her projected release date looming in the not-too-distant future.

The name "Holly Boisvert and Brandon" is inextricably linked to the 2002 stabbing death of 17-year-old Stacy DeGrandchamp, a case that baffled police for years before a long-awaited arrest and confession finally brought a measure of closure to the victim's family. The entire confrontation was sparked by a petty, yet deadly, rivalry over Brandon Muff, Holly's ex-boyfriend and Stacy's new partner.

The Jealousy That Led to a Cold Case in Fort Wayne

The foundation of the tragedy was a toxic mixture of teenage drama and escalating jealousy. Holly Boisvert and Stacy DeGrandchamp were once close friends, but their bond fractured when Stacy began dating Brandon Muff. Brandon, who was a few years older and had recently graduated high school, was Holly's ex-boyfriend. Holly, just 15 at the time, was reportedly obsessed with the idea of reconciling with Brandon, and Stacy’s new relationship with him was a massive point of contention.

On the night of August 15, 2002, a chaotic house party was taking place at a residence on Guthrie Street in Fort Wayne, Indiana. Both Holly and Stacy were in attendance. Witnesses later recounted that a verbal argument between the two girls quickly escalated into a physical altercation. The fight was reportedly brief, with other teenagers stepping in to separate them. Tragically, in the chaos, Stacy DeGrandchamp was stabbed twice.

Despite being rushed to a local hospital, Stacy succumbed to her injuries. The initial investigation into the murder was complicated by the large number of witnesses at the party, many of whom were uncooperative or offered conflicting accounts. Although Holly Boisvert was an immediate person of interest, the case went cold for years. The lack of concrete evidence and the silence of the partygoers allowed the case to stall, leaving the DeGrandchamp family without justice for nearly two decades.

The Arrest, Confession, and Sentencing Update

The case remained a Fort Wayne cold case until new forensic techniques and renewed investigative efforts brought it back into the spotlight. In a major breakthrough, Fort Wayne Police arrested Holly Boisvert in 2019, 17 years after the murder. At the time of her arrest, Boisvert was 33 years old.

The arrest was a result of a combination of factors, including new witness testimony and the re-examination of old evidence. Boisvert was extradited to Indiana to face charges. In a move that finally provided a clear resolution to the case, Holly Boisvert entered a plea deal in 2021. She pleaded guilty to the lesser charge of Voluntary Manslaughter rather than the original murder charge.

During her sentencing, Boisvert offered an apology for her actions. She was sentenced to 25 years in prison. This conviction finally closed the book on one of Allen County's most enduring cold cases, a story that was later featured on the Investigation Discovery (ID) series Mean Girl Murders.

Where is Holly Boisvert Now? The 2030 Release Date

The most pressing question for those following the case is the current status of the convicted killer. As of late 2025, Holly Boisvert is incarcerated at the Indiana Women's Prison in Indianapolis.

Boisvert, who is now in her late 30s, is serving her 25-year sentence for the voluntary manslaughter of Stacy DeGrandchamp. Due to Indiana's sentencing guidelines, which include credit for time served and potential good behavior, her sentence is significantly reduced from the full 25 years. According to her inmate records, Holly Boisvert's earliest possible release date is projected to be March 25, 2030.

This date marks the end of a long, painful chapter for the families involved. For the DeGrandchamp family, the conviction and ongoing incarceration represent a form of justice, though it can never fully heal the wound left by Stacy’s untimely death. The case serves as a stark reminder of how quickly teenage disputes, fueled by intense emotion and jealousy over a relationship with figures like Brandon Muff, can turn into permanent tragedy.

The story of Holly Boisvert, Brandon Muff, and the murder of Stacy DeGrandchamp remains a critical piece of the Fort Wayne criminal history, illustrating the painstaking work of cold case detectives and the long, difficult path to justice.
