FORT WAYNE, Ind. (WFFT) - It was a cold case older than its victim.
Stacy DeGrandchamp was just 17 years old when she was stabbed to death in Fort Wayne in August of 2002.

Now 18 years later, police arrested and charged 33-year-old Holly Boisvert with murder in her death.
"I think for the family, this is a relief to finally get an arrest because I don't think they anticipated this would happen," JAVA Board Member Amy Davis said.
A probable cause affidavit released this week says the girls were both teens, and even friends, before it happened.
On August 15, 2002 the two were mad at one another.
It said Boisvert followed DeGrandchamp into a backyard and they yelled until they fell to the ground while kicking and pulling hair.
When DeGrandchamp got up she was bleeding, but the affidavit said no one who was there that night ever saw a knife.
Boisvert reportedly told police she must have landed on something.
The case grew cold.
Then the justice advocacy nonprofit JAVA, encouraged the family to keep pressing for answers.
"Once we did it on our public access channel for JAVA, we were able to share that link and from what I think tips may have been called in from us sharing that. I'm not sure if they were called in or through social media, but there were people in the community that commented and knew about the case," Davis said.
Police continued the investigation which led them to Boisvert now living in Wisconsin.
The affidavit said Boisvert gave investigators the knife used to kill DeGrandchamp.
They said she also told them “I think I killed my best friend ... and that it wouldn't have happened had she walked away.”
Davis said having a new set of eyes on the case helped.
