What started as a night of drinking between neighbors in Utah ended in a deadly stabbing — and now the man responsible has learned his fate.

Gerald Vandermeer, 57, has been sentenced after admitting he killed his neighbor, 45-year-old Cory Whittenburg, during a violent argument in Cedar City.

Vandermeer pleaded guilty to homicide by assault as part of a plea deal that reduced his original first-degree murder charge.

According to court reports, the two men were neighbors who spent the evening of Feb. 12, 2025 drinking heavily together. Vandermeer reportedly showed up at Whittenburg’s home with a bottle of vodka and a case of beer. During the gathering, the men also used THC, according to statements presented during Vandermeer’s March 4 sentencing hearing.

At some point during the night, the situation spiraled out of control.

Investigators said the two men began arguing, though Vandermeer later told police he couldn’t remember exactly what the fight was about.

What is known is how it ended.

Authorities were called to the home after reports of both a stabbing and a gunshot. When officers arrived, they encountered Vandermeer first. He had visible injuries, including cuts on his face and hands.

Inside the home, they found Whittenburg dead.

The victim had suffered multiple stab wounds, including two severe wounds to his back.

During the sentencing hearing, Vandermeer’s attorney argued that his client had been in a severely distressed state following the fight.

Defense lawyer Richard Gale told the court Vandermeer was “in a very traumatized mental state” after the confrontation turned violent, noting that both men had been injured and that alcohol and THC played a role in clouding his judgment.

Gale also pointed out that Vandermeer suffered stab wounds and even a broken ankle during the altercation.

But prosecutors said the most disturbing detail came after the attack.

Instead of calling for help, Vandermeer left the scene while Whittenburg was dying.

“This case involves the loss of human life,” prosecutor Shane Klenk told the court. “Cory Whittenburg is dead as a result of a violent encounter with the defendant.”

Klenk emphasized that Vandermeer abandoned the victim rather than trying to save him.

Following the hearing, the judge sentenced Vandermeer to up to five years in prison. He will also have to pay $5,800 in restitution, plus interest, to cover funeral expenses and other related costs.

The deadly confrontation has left a Cedar City neighborhood shaken — a tragic reminder of how quickly a night of drinking can spiral into irreversible violence.
