IDAHO FALLS — After a week-long trial, a jury found Mark Bent guilty of first-degree murder Monday night.
Bent, 43, was convicted of murdering Nikolas Todd Bird on Sept. 3, 2022. He was also found guilty of using a deadly weapon in the commission of a felony.
Shortly after the shooting, Bent reportedly admitted to the killing on Facebook.
This was a key part of Bonneville County Deputy Prosecutor Steven Haderlie’s closing arguments.
“My main goal was to kill Nik Bird,” Haderlie quoted from Bent’s Facebook post. “I tried to talk myself out of it. I followed through with said plans. You never know when someone is going to decide to do something about it, like me.”

Haderlie said the post was published on Sept. 3, 2022 at 10:31 p.m — minutes after the shooting.
Bent sent his parents a similar Facebook message.
“Mom and Dad, I’m really sorry to tell you this, but I have just committed murder of someone in the car scene here that was involved with slandering and threatening me and I’m either going to jail for the rest of my life or going to commit suicide,” the message read.
According to Haderlie, Bird’s autopsy showed that the angles of the bullet wounds suggest that Bent shot Bird while Bird lay on the ground.
On Friday, Bent testified that he “blacked out” during the shooting.
Haderlie told the jury the alleged blackout was not mentioned in Bent’s conversation with his parents, his father’s 911 call, or the Facebook post.
But in these instances, along with a phone call to his dad and his testimony in court, Haderlie noted Bent confessed to the murder five times. Bird did not threaten Bent, Haderlie said, and there was no cause for his murder.
Defense’s closing arguments
Bent’s defense attorney, Serhiy Stavynskyy, said there were discrepancies in the times events took place and criticized the state for bringing Bent’s father as a witness.
Stavynskyy argued the state failed to prove the murder was premeditated, which is a requirement for first-degree murder convictions.
“He (Bent) has a dashcam in his truck that records every single moment of his driving. He has a phone on him. He drives around. He calls the police and tells them what happened. This is not a premeditation case, and the state hasn’t shown anything to indicate that,” Stavynskyy said.
Prosecutor Randy Neal argued that Bent would not have driven to Idaho Falls to visit the friends from the car club who had been harassing him, of whom he was afraid. He also reminded the jury that Bent testified that he looked up Bird’s address, and driving to his neighborhood was not happenstance.
“My main goal was to kill Nik Bird and I just coincidentally did during a blackout,” Neal said of Bent’s testimony.
Bent’s sentencing is scheduled for Feb. 10. He could face life in prison, under Idaho law.
