FARGO — Court records indicate the 22-year-old man recently charged in the stabbing death of a 14-year-old middle school girl in Fargo was looking forward to becoming a first-time father and wrestling with anger issues in 2017 when he was involved in an assault case in Morton County District Court.

In that case, Arthur Prince Kollie pleaded guilty to hitting a corrections officer in the face, later writing to a judge that he reflected on his anger issues and wanted to turn his life around so he could support an expected child.

In the most recent case against Kollie, prosecutors accused him of murder, robbery and aggravated assault in the death of Jupiter Paulsen, who suffered fatal wounds in a knife attack on June 4 and was pronounced brain dead on June 8.

In the 2017 Morton County case, Kollie, who according to recent court records has no permanent address, pleaded guilty to hitting a woman in the face while he was being held at the North Dakota Youth Correctional Center. Available court records do not indicate why Kollie was committed to the facility.

The woman Kollie admitted to striking in the face was a juvenile institutional residential specialist who worked at the youth correctional center.

In the Morton County case, Kollie was sentenced in October 2017 to a year behind bars, with 189 days stayed. He was also given credit for having served 176 days and was placed on supervised probation for two years.

Court records show prosecutors later alleged Kollie committed several probation violations, including failure to show up for probation appointments and marijuana use.

In July 2019, the court ruled Kollie committed one or more probation violations and sentenced him to serve one year, with credit for having already served 199 days.

Letter to the judge

Later that same month, Kollie wrote to Morton County District Judge James Hill asking for a sentence reduction so he could work to support family members.

"My girlfriend are expecting a new member in our family and ima be a dad for the (first) time in my life," Kollie wrote, closing his letter with: "I put my trust in god to lead me in my Life (journey) to be the best dad and person to my family and friends."

He also wrote that he learned a lot while on probation, including that he should talk about his problems instead of holding them in and ask for help when necessary instead of trying to handle things his own way.

Kollie asked the judge to reduce his sentence or consider placing him under house arrest at the home of his mother in Fargo.

Judge Hill denied Kollie's request, as well as a follow-up request Kollie made asking that he be allowed to finish his sentence at a halfway house in Fargo.

In his follow-up request, Kollie stated in a note to the judge: "I've had time to reflect on my anger and realize I'm smarter than what I did and am still a good person. ... I want to rebuild my life and reputation, start working for my family and move past these mistakes and move forward."

It is not clear when Kollie was released from the sentence imposed in July 2019 for probation violations in the Morton County case, but his adult court history in Cass County begins with traffic-related cases in October 2020.

Those cases were followed by a felony case in Cass County in December 2020, in which Kollie faced several charges, including unlawful possession of a firearm by a felon and discharge of a firearm within city limits.

In that case, a police report filed with the court stated that on Dec. 13, 2020, officers were sent to Kollie's apartment on a report of a single gunshot.

Kollie, described in the police report as intoxicated, stumbled out of the apartment and told officers he fell and hit his head. Police ultimately searched the apartment and found at least one gun and ammunition, according to court documents.

Kollie pleaded guilty to a number of charges in that case, including being a convicted felon in possession of a firearm.

On May 7 of this year, Kollie was sentenced to two years behind bars, with all but 27 days stayed. He was given credit for having served the 27 days.

He was ordered to obtain a diagnostic assessment within 60 days of being released and to follow all recommendations. He was also placed on supervised probation for 18 months.

Kollie's Cass County convictions also include a misdemeanor criminal trespass conviction stemming from a Jan. 15 incident, in which he admitted he refused to leave a Fargo Petro Serve USA store when asked to do so by store workers.

In that case, Kollie was sentenced on April 26, to 30 days in jail, with 25 days suspended. He was also placed on unsupervised probation for 11 months.

In another Cass County case, Kollie was arrested on June 1, just days before Paulsen was stabbed, following a fight at a bar in downtown Fargo.

According to court records, Kollie was walking away from the scene of the fight when officers arrived, and he ran away when officers told him to stop.

Kollie was arrested and pleaded guilty to a charge of resisting officers. A conviction was deferred for 11 months on the condition he satisfactorily complete 11 months of unsupervised probation and pay $400 in fines, according to court records.

The Jupiter Paulsen case

In the pending murder case, Kollie is accused of killing Jupiter Paulsen, who was riding a skateboard the morning of June 4 when she was attacked apparently at random, according to her father, Robert Paulsen.

Jupiter Paulsen was choked and stabbed more than 20 times over the course of about 20 minutes, according to her father and court records. The attack that occurred near Party City, 4340 13th Ave. S. in Fargo, was partly captured on security video.

Kollie faces charges of murder, robbery and aggravated assault in connection with the attack.

According to court records:

Kollie was arrested following an investigation that began June 4 after a garbage worker witnessed a man leaning over Jupiter Paulsen with one hand on her nose and the other on her throat.

The teen's attacker ran from the area, but police later traced him to a Walmart store about half a mile west of where the stabbing occurred.

Surveillance video from Walmart showed an individual grabbing new clothing, putting it on in a changing room and leaving without paying. Police found discarded shoes and clothing covered in blood in the changing room.

Later, police found a man matching the description of the individual who took clothing from Walmart and identified him as Kollie.

Questioned by police, Kollie said he used methamphetamine the afternoon of June 3 and denied any role in the assault on the morning of June 4, according to court documents.

Kollie told police he was walking in the area where the assault occurred but repeatedly said he did "not recall" when asked about the incident.

Kollie is being held in the Cass County Jail, with a bail amount of $1 million. The Forum's attempts to interview Kollie at the jail were unsuccessful.

Jupiter Paulsen underwent surgery June 4 following the attack, but her father said later that day it was not clear if she would completely recover.

In a June 7 update to an online fundraiser for his daughter's medical bills, Paulsen said it was unlikely she would survive.

"We just got word from the Doctor today that Our baby girl is too far gone and there isn’t anything they can do. Just to gather family and to say our goodbyes," the update said.

On June 8, Robert Paulsen said his daughter died, and her organs were being readied for donation.

In recent cases in Cass County District Court, Kollie indicated he was homeless, but in earlier cases he listed an apartment at 4430 9th Ave. Circle S. in Fargo as his home.

Residents of the building told The Forum Kollie used to live in an apartment there, but they had not seen him since last year and did not know him well.

In his communication to the judge in the Morton County case involving the assault on a corrections officer, Kollie said his mother lived at an address in Fargo. The Forum's attempts to speak with the residents of that address in person were not successful.
