A Wasilla man was stabbed to death after a dispute over a vehicle at a home on Knik-Goose Bay Road Wednesday night, according to Alaska State Troopers. Michael R. Plummer, 43, died at the scene.

A Thursday AST dispatch on Plummer's death says troopers received a call at about 10:24 p.m. reporting an altercation at a Knik-area home near Mile 15 of Knik-Goose Bay Road, with one person likely dead.

Troopers say Plummer and his fiancee Jessica Smith -- whose parents owned the home -- were present with another woman, when the woman's husband and two other men came to the house to get a pickup truck the couple shared. A confrontation ensued when they arrived, however, during which troopers say Plummer was stabbed.

Gunfire from inside the home then hit one of the three men, who fled in two vehicles.

Smith says Plummer was only trying to get the men out of the house, and he didn't have any weapons.

"When I saw Mike falling he was stabbed in the throat," Smith said. "I grabbed my dad's gun -- I shot at them and I hit her husband in the shoulder, and then they ran away."

One of the vehicles was found unoccupied near Mile 14 of Knik-Goose Bay Road, with troopers saying it was inoperable due to a damaged tire. A K-9 handler with the Wasilla Police Department helped troopers trace tracks from the vehicle to the woods, but no one was located. AST said there were signs that a second vehicle stopped near the location before headings towards Wasilla.

Personnel from the Alaska Bureau of Investigation's Mat-Su Unit were called in to assist with and ultimately assume control of the investigation.

Shortly after the altercation, Mat-Su Regional Hospital staff told troopers a man with a gunshot wound arrived at the emergency room for treatment. Troopers visited the hospital and determined that he was one of the people involved in the altercation; the extent of his injuries were not known Thursday.

"It is believed that all parties associated with this incident have subsequently been contacted or identified," troopers wrote.

AST spokesperson Megan Peters said Thursday that the investigation into Plummer's death was still in progress and many details -- including whether troopers are still looking for suspects and whether any charges are yet pending -- can not currently be released.

Meanwhile, Smith said she was still coming to terms with the loss of her fiance.

"This is about nothing more than a couple fighting and their problems got brought to my doorstep; I don't know what they were here for or came into the house -- they killed him 'cause he was tring to get them out," Smith said. "I just lost my partner and my baby's dad and I don't understand why Mike; we didn't never do anything to them. I don' t know -- it's terrible."
