FORT WAYNE, Ind. (WANE) — Update: Holly Boisvert has been taken into custody at the Allen County Jail. WANE 15 will update this story as more details become available.
An arrest has been made in a Fort Wayne cold case dating back to 2002.
Fort Wayne Police on Wednesday arrested 33-year-old Holly Boisvert on a charge of Murder in the August 2002 stabbing death of 17-year-old Stacy Degrandchamp. Boisvert would have been 16 at the time.
According to a probable cause affidavit, Boisvert stabbed Degrandchamp during a fight in the backyard of a Fort Wayne home on Aug. 15. Fort Wayne Police were called to the scene around 10:50 Thursday night. They found Degrandchamp lying in the driveway bleeding.
Early on authorities knew that Degrandchamp and another girl were fighting. The girl Degradchamp was fighting with was questioned shortly after the stabbing. Investigators interviewed a number of witnesses who said they tried to break up the fight.
According to court documents, one witness told police that Boisvert said that, “Degrandchamp is going to take an [expletive] whipping tonight,” then went to the backyard and began to argue with her. The argument became physical, according to a probable cause affidavit. The two fell onto the ground and began fighting, kicking and hair pulling, the affidavit said.
Degrandchamp would have started her senior year at Wayne High School the week following the fatal stabbing.
A second witness pulled Degrandchamp away from the fight. That witness told police Degrandchamp took a few steps to leave before falling to the ground. She had blood on the front of her shirt that was not there prior to the fight, according to court documents.
In September 2002, Boisvert was interviewed by Fort Wayne Police detectives. Boisvert told police that she was sitting on the front porch of the home when Degrandchamp arrived. Another person who was at the home told her Degrandchamp was outside but assured Boisvert that Degrandchamp had “no problem” with her so it was okay to go out there.
According to court documents, Boisvert told police that she heard Degrandchamp yell, “what is she doing here?” as she started to walk out of the back door. Boisvert said she heard Degrandchamp talking about one of her friends and that’s what “set her off.”
Boisvert told police that she started yelling at Degrandchamp and they got in each other’s faces. According to Boisvert, Degrandchamp pushed her and she fell over into some recycle bins. She said Degrandchamp grabbed her by the hair and drug her from the recycle bins to a grassy area of the yard. That’s when Boisvert said she grabbed Degrandchamp by the wrists and threw her down on the ground where they were kicking each other.
She told detectives she did not have a knife.
When a detective asked how Degrandchamp got stabbed, Boisvert said she “probably landed on something when she got knocked into a recycle bin.”
In Jan. 2003, a witness told police that Boisvert changed into sweats and pulled her hair into a ponytail before confronting Degrandchamp. A few days after the stabbing the witness said Boisvert told him that she had a knife on Aug. 15.
After Degrandchamp was stabbed the witness said Boisvert said she washed her hands and put the knife on or near a car that was parked in front of the house. However, the witness said Boisvert denied stabbing Degrandchamp.
Police said they’d worked over the last year “reviewing evidence, conducting forensic testing and interviewing multiple witnesses in several states” before a warrant was issued for Boisvert’s arrest on Tuesday.
In Dec. 2019, a Fort Wayne Police detective interviewed Boisvert in Fond Du Lac, Wisconsin, where she current lives. According to court documents Boisvert appeared to be upset and had tears in her eyes. The detective was present when Boisvert said, “I think I killed my best friend and that’s why you’re here” and “If I had just walked away and not turned around to fight.”
Boisvert also voluntarily gave police a knife she had during an interview months earlier, which matched the one used to kill Degrandchamp, according to the affidavit.
Detectives arrested Boisvert in Fond Du Lac, Wisconsin. She was brought back to Fort Wayne to face charges.
