A man found guilty of assaulting a Roseville police officer at a Walmart was sentenced to three years of probation this week.
Collin Scott Magnuson, 32, of St. Paul, received a sentence of one year in prison, which was stayed for three years, and a 77-day sentence, which he’s already served.
State sentencing guidelines did not call for prison time, though the Ramsey County Attorney’s Office asked that he be sentenced to more jail time. Magnuson’s attorney, Thomas E. Harmon V, argued against it during Monday’s hearing.
Magnuson opted for a bench trial and Ramsey County District Court Judge Maria Mitchell ruled in May that he was guilty of fourth-degree assault of a peace officer causing demonstrable bodily harm and not guilty of third-degree assault causing substantial bodily harm.
Harmon wrote in a closing argument to the court that the case “is about the unfortunate convergence of two people battling their respective demons. Mr. Magnuson battles alcohol” and he noted that Roseville Sgt. Ryan Duxbury sustained a traumatic brain injury when he was shot in the line of duty in 2022.
“On March 5th, 2025, they both lost, and we as a society are the worst for it,” Harmon wrote. “Mr. Magnuson does not pretend that his poor decision making before he entered Walmart that evening didn’t lead to this encounter. That does not mean he broke the law. That does not mean he was looking for a fight. That does not mean he deserved to be slammed to the ground.
“It means he has the right to hold the government to its burden of demonstrating proof beyond a reasonable doubt,” Harmon continued. “The government has failed to meet its burden.”
But Assistant Ramsey County Attorney Allison Fredrickson wrote that Duxbury “was using the de-escalation techniques that he had been taught: to talk to Mr. Magnuson, to use a calm voice, to give warnings and ask him to do things, like enter the office. Mr. Magnuson was told that he would be handcuffed if he did not comply. Immediately, Mr. Magnuson said no and pushed his weight into Sgt. Duxbury and grabbed his jacket, as if to leave.
“Sgt. Duxbury did not slam Mr. Magnuson to the ground,” she continued. “He testified that he grabbed his arm to handcuff him and when he did not comply, he tried to get him in the best position to put him in handcuffs to detain him. Sgt. Duxbury was doing his job, he was asked to assist in the apprehension of a shoplifting suspect.”
Fredrickson also noted there was no evidence presented at trial that Magnuson was under the influence.
On March 5, a Walmart asset protection officer saw Magnuson, who was at self-checkout, didn’t scan all the items he selected and then began walking out of the Roseville store, Mitchell wrote in a court document about her findings of fact.
Duxbury was working contracted overtime at Walmart and was notified by loss prevention about the suspected theft.
From the assault, Duxbury sustained cuts and bruising on his hand, had bruising on his face and experienced headaches, Mitchell wrote. He went to the doctor and did not receive a diagnosis of a concussion.
“It’s unfortunate that people, while committing crimes, … think that it’s OK to assault a police officer,” Roseville Deputy Police Chief Joe Adams said Tuesday. “It should be clear that if you’re going to assault a police officer, we’re going to partner with the Ramsey County Attorney’s Office and hold you accountable.”
