Tyson Michael Goodsell: The North Mankato homicide investigation and seven-defendant prosecution

NORTH MANKATO — Tyson Michael Goodsell was 17 when he was fatally shot on May 23, 2026. What began as a late-night gunfire call in a residential neighborhood developed into a prosecution involving seven defendants, allegations of a planned robbery and efforts to conceal evidence, and separate weapons cases.

This account follows the publicly reported investigation through October 29, 2026. The charges and statements attributed to defendants are allegations, not findings of guilt. The sources reviewed do not establish a final disposition for every defendant.

Remembering Tyson

Tyson attended Mankato West High School and played football. His mother, Carissa Weber, described a teenager looking forward to graduation and greater independence. The family account describes her last conversation with him around 10 p.m. on May 23, when he asked about borrowing a tent for a camping trip.

May 23: gunfire, a crashed vehicle and lifesaving efforts

Police were called around 11:03 p.m. to Pleasant View Drive and Willow Lane after reports of gunshots. They then learned a vehicle had crashed into a townhome on Willow Trail. Officers found Tyson wounded inside, removed him and attempted lifesaving measures. He was taken to Mayo Clinic Health System in Mankato, where he was pronounced dead.

KEYC’s initial investigation report described the police response and the first arrests. The homicide investigation was led by North Mankato police in Nicollet County.

The alleged robbery plan

According to criminal complaints described by local news outlets, a meeting presented as a cannabis-product sale was allegedly arranged to rob Tyson. Prosecutors accused Ryan Robert Wolner of helping organize the plan and obtain a rifle. Reports describe different dollar amounts for the proposed purchase and the products targeted; those figures should not be treated as an established loss.

FOX 9’s June 4 account of the complaint says Abdikhadar Fakhi Mohidin approached Tyson’s vehicle. Investigators alleged that Tyson tried to drive away, ran over Mohidin’s foot, and Mohidin fired six rifle rounds. The complaint also attributed statements about the shooting and later discussions about hiding evidence to the suspects. These are prosecution allegations; the reporting does not resolve possible defense challenges to those accounts.

June: the first charges

On June 4, North Mankato police announced seven felony charges against Mohidin: second-degree murder, attempted first-degree aggravated robbery, conspiracy to commit first-degree aggravated robbery, a firearm or ammunition offense, and three assault counts.

The same release announced five additional counts against Ahmed Fuad Mohamud involving alleged obstruction and aiding assaults. He had initially faced attempted aggravated robbery and conspiracy charges. The release is a dated account of the charges announced then, rather than a certification of each case’s current status.

Wolner initially faced robbery-related and aiding-an-offender charges. Later reporting described nine felony counts against him in the Nicollet County case, including aiding and abetting second-degree murder. That later description is important: the five-count initial summary does not capture the subsequent prosecution.

Reports also described Mohidin and Wolner as having been on conditional release in separate cases. Those pending matters are distinct from the Goodsell prosecution and do not establish guilt in either case.

August: additional defendants and evidence allegations

KEYC reported charges against Christa Marie Wolner, Ryan Wolner’s mother, involving alleged obstruction and helping an offender avoid arrest. The complaint accused her of helping search for discarded phones, funding lodging for co-defendants and assisting with evidence after the shooting. Those alleged actions remain subject to court proceedings.

An August 4 report identified two more defendants: Jaxon Sageng and Devon Bakke. Sageng was accused of supplying the phone and vehicle used to arrange the meeting. Bakke was accused of storing and later moving the rifle. Their alleged roles differ from the allegation that Mohidin fired the shots.

By September, reporting identified seven people charged in connection with the case: Abdikhadar Fakhi Mohidin, Ryan Robert Wolner, Ahmed Fuad Mohamud, Ahmed Mohamed Mohamud, Christa Wolner, Jaxon Sageng and Devon Bakke. Ahmed Fuad Mohamud and Ahmed Mohamed Mohamud are different defendants.

A separate August weapons case

A further development came in KEYC’s August 26 update. It reported a separate Blue Earth County felony machine-gun charge against Ryan Wolner based on an alleged firearm conversion device. According to the complaint as reported, a BCA analysis linked a DNA profile on the device to Wolner, and investigators examined monitored jail calls about retrieving items before a search.

That report specifically said Christa Wolner had not been charged in that machine-gun complaint at the time of the update. The alleged DNA result concerned a conversion device; it should not be described as proof that ballistic testing connected a particular rifle to Tyson’s death.

September: prosecutors seek enhanced sentences

KEYC’s September report said prosecutors sought upward sentencing departures for several defendants if convicted, citing alleged group participation and planning. It also reported that assistant attorneys general joined Nicollet County prosecutors in the related cases.

An enhanced-sentencing request is a prosecution position. It is not a sentence, conviction or judicial finding that the alleged aggravating factors have been proven.

October: Wolner arrested again

FOX 9 reported October 22 that Wolner had been arrested following an October 19 domestic-disturbance call in Mankato while out on bail. Police allegedly found two unserialized handguns in a backpack linked to him, one equipped with a conversion device. New weapons charges were reported in Blue Earth County.

These October allegations are separate from both the homicide prosecution and the August weapons complaint. KEYC reported a hearing scheduled for October 29 at 2:30 p.m.; an outcome for that hearing was not verified for this article.

Reported upcoming court dates

KEYC reported October 13 that Ahmed Fuad Mohamud’s pretrial hearing was set for November 30, 2026, at 10:30 a.m. in Nicollet County District Court. His jury trial was scheduled for January 4–15, 2027, beginning at 8:30 a.m. on January 4. Court dates can change; these are the dates reported in that update.

The public accounts reviewed do not establish final forensic conclusions, all defense positions or the ultimate resolution of every charge. Each defendant is presumed innocent unless proven guilty.
