Summit County prosecutors formally charged Austin Kenneth Garceau, 38, with murder on Wednesday, July 29, in the fatal stabbing of 34-year-old Damon Enman at a short-term rental on Deer Valley Drive. It is Park City's first homicide in nearly nine years.

Garceau, of Salt Lake County, faces a first-degree felony, according to TownLift. He is being held without bail at the Summit County Jail and is scheduled to make his initial appearance in 3rd District Court on Thursday, July 30 at noon.

The charge advances a case that began on Friday, July 24. As we reported July 27, Enman called 911 from a rented house at 505 Deer Valley Drive at approximately 8:30 a.m. that morning, telling the dispatcher Garceau had threatened to kill him and then stabbed him. Male voices could be heard on the call yelling "Austin, stop!" according to court documents.

New charging documents show a preliminary medical exam found Enman was stabbed more than 10 times. He was airlifted to the University of Utah Hospital, where he was pronounced dead shortly after 10:30 a.m. The Office of the Medical Examiner ruled the death a homicide caused by multiple sharp force injuries.

Three witnesses were inside the home during the attack. One told investigators Garceau called Enman "a reptilian" before stabbing him. That witness jumped on Garceau's back and bear-hugged him, repeatedly telling him to drop the knife. Garceau eventually let it go and said, "What did I do?" according to the probable cause affidavit.

Police requested the no-bail hold because Garceau is reportedly close friends with the witnesses, which officers said could put them in danger if he were released. Park City officials have said the confrontation appeared to be an isolated event with no continuing threat to the public.

Parents speak for the first time

Enman's mother, Heather Thorstenson, told KPCW on Wednesday that she and her husband, Jim Thorstenson, were shocked by their son's death but feel some comfort now that Garceau has been charged.

"I feel better knowing that he's been arrested, that, you know, there are consequences to our actions," she said.

The Thorstensons said their son had struggled with addiction for years but had recently graduated from a recovery program. His mother said he had maintained sobriety, was passing drug tests, and was working to get his life back on track.

The family expressed no anger toward Garceau. Heather Thorstenson said she feels sadness for him and his family, speculating drugs may have been involved. Authorities have not confirmed whether substances played a role.

Jim Thorstenson said following media coverage of his son's death has been surreal. He described Enman, known to friends as "Dae," as someone who made people feel heard and special. Dozens of friends have posted tributes on social media since his death, and an online fundraiser is underway to help cover funeral costs and support the family.

Garceau's Thursday court appearance will be his first since the formal murder charge was filed.
