Authorities say a man shot a student outside a southern Minnesota high school Friday morning before dying by suicide.

All Stewartville Public Schools classes were canceled for the day after the shooting, which occurred around 5 a.m., according to Olmsted County Sheriff Kevin Torgerson.

The sheriff said roughly 40 members of the wrestling team were boarding a bus outside the high school when they heard a gunshot and saw a member of the team on the ground in the parking lot. 

Coaches tended to the injured teenager before he was taken to a hospital. While they were rendering first aid, they heard a second shot and found a man on the ground nearby with a rifle in his hand. Investigators said the man died from a self-inflicted gunshot wound at the scene.

"Those coaches did a phenomenal job right from the get-go to help the juvenile victim," Torgerson said.

The sheriff said the teen was immediately taken into surgery and is in critical, but stable, condition.

Officials said the connection between the man and the teen is not yet known, and neither has been identified publicly. What led to the shooting is under investigation.

Torgerson called a shooting like this "very rare" for Stewartville.

"We just don't have that kind of thing here," he said.

Stewartville Public Schools Superintendent Belinda Selfors said school will resume on Monday. High school choir concerts that were scheduled for Sunday and Monday are postponed.

"We are here to support our students, our staff and our communities in any way that we can," Selfors said.

After the shooting, the wrestling team members were reunited with their families nearby.

State Sen. Carla Nelson, a Republican who represents Stewartville, called the shooting "tragic."

"My prayers are especially with the student who is fighting through surgery, with their family, and with the families, classmates, coaches, and teachers as they grieve from this unimaginable shock and pain," Nelson said. "I am grateful to law enforcement and first responders for acting quickly. May we all hold this community and everyone involved in our strongest prayers."

The Rochester DFL Delegation, which consists of Rep. Tina Liebling, Rep. Andy Smith, Rep. Kim Hicks and Sen. Liz Boldon, said the community has been "forever changed" by the incident.

"We're grateful to local law enforcement for a swift response and are thankful that a greater threat is not posed to the school at large," the delegation said. "However, this is yet another chilling example of the threat our students feel every single day. High schoolers should be focused on things like exams and how they're going to spend winter break – not what to do in an active shooter situation. Our hearts are with the student who was injured and their family as they experience the unimaginable."

A Friday night basketball game has also been canceled.

"Like most people ... you think, it can't happen here," Rick Scott, a pastor at a nearby church, said. "It's such a shock. A close-knit community."

Stewartville is about 12 miles south of Rochester.
