A Torrington teen killed in town on Friday died of stab wounds to the head, neck, torso and extremities, according to the medical examiner's office.
The death of Holly Aeschlimann, 19, of Torrington has been ruled a homicide.
The office of the chief medical examiner in Farmington said that Aeschlimann died of sharp force injury of head, neck, torso and extremities.
Heather Birden, 20, also of Torrington, has been identified by police as the suspect, but she still has not been charged yet.
Police received a disturbance call at 1:12 a.m. on Friday in the area of Prospect and Hungerford streets, responded and learned from a passerby that Aeschlimann had been injured and taken to Charlotte Hungerford Hospital.
Authorities later learned she has died from her injuries, police said.
Multiple people who spoke with NBC Connecticut indicated that there was bad blood between the victim and the suspect and police said there's been an ongoing history between them. Friends told NBC Connecticut that Aeschlimann was riding her bike in the area when she was attacked by another young woman with an axe to grind and a knife in her possession.
Birden is not being charged as of yet, police said, but was arraigned Friday in Bantam Superior Court for an active arrest warrant issued by the Winchester Police Department for an unrelated case from Aug. 7. She was charged with assault in the second degree, reckless endangerment and breach of peace in that case. Friends said that the other case also involved a stabbing, but that is not confirmed with police. Birden was also charged with violation of probation.
While friends aren't sure how or when the feud between the victim and suspect started, they said the two had scuffled about a year ago.
"I guess she was trying to get back at her for something that happened, that she started," Thomas Farr, Aeschlimann's cousin, previously said.
Their latest dispute was apparently about a man.
"I know that Heather liked the guy, but I know that Holly was just hanging out with him," Maddie Brown, another friend of Aeschlimann's said.
Three friends were with Aeschlimann at the hospital, Brown said.
The investigation in the stabbing is ongoing and the Connecticut State Police Major Crime Squad is assisting.
No additional information has been released.
There was an impromptu gathering on Friday night in Aeschlimann's memory and there was an organized vigil on Sunday.
