Wisconsin Woman Accused In Cold Case Killing Of Best Friend

A Wisconsin woman has been taken into custody and is awaiting charges in a cold case killing that occurred when she was a teenager.

Fort Wayne Police arrested Holly Boisvert, 33, on Wednesday in connection with the 2002 killing of Stacy Degrandchamp, 17. Boisvert is currently being held in a Wisconsin jail on suspicion of murder, according to the Fon Du Lac Reporter.

Degrandchamp was stabbed to death at a Fort Wayne, Indiana home on Aug. 15, 2002. Boisvert was a teenager at the time and was fighting with Degrandchamp that night, local outlet WANE reported. Multiple witnesses reported seeing the two get into a physical altercation that night.

However, when Boisvert spoke to police in 2002 about Degrandchamp’s death, she denied she had a knife on her during the fight and claimed that the other girl might have gotten stabbed when she was knocked into some recycling bins during the altercation, Indiana's WPTA21 reported.

Despite authorities interviewing numerous individuals who witnessed the brawl between the two girls, Degrandchamp’s case went cold until police began investigating again in 2019, WANE reports. Police told the station that they spent a year “reviewing evidence, conducting forensic testing, and interviewing multiple witnesses in several states” before they were able to issue a warrant for Boisvert’s arrest this week — and allegedly get a confession.

Det. Brian Martin said that after initially contacting Bosivert in 2019, “she seemed somewhat surprised but we were able to speak to her for approximately two hours,” according to a WPTA21 report.

Boisvert allegedly admitted to the killing then, telling police, "I think I killed my best friend," and, "If I had just walked away and not turned around to fight," according to court documents filed in the case, WPTA21 reported.

It was during that conversation that Boisvert handed over a knife she had with her on the night of the murder to police, the station reports. Authorities then turned the weapon over to a pathologist in Allen County, who was able to conclude that the knife was the correct size to have been used to inflict the fatal wounds that killed Degrandchamp nearly 20 years ago.

Degrandchamp was killed a week before she was slated to begin her senior year at Wayne High School, according to the WANE report. She died of her wounds at a local hospital, according to a 2002 obituary.
