Officials believe a 19-year-old man is responsible for a murder-suicide in Olmsted County.
Deputies responded to a medical call Monday night and discovered the man and woman in the shed near a house. The property is located on the border of rural Oronoco and Pine Island off of County Road 12.
Authorities said they found 18-year-old Kayla Jill Koranda, of Rochester, with what appeared to be a gunshot wound. She died at the scene.
Authorities also found 19-year-old Nicholas Bryan Roecker, of Pine Island, with a gunshot wound. Roecker was taken to Mayo Clinic where he later died.
Olmsted County Sheriff David Mueller said investigators believe Roecker had the gun and shot the two of them. They also believe he had mental health issues.
Roecker's father found the two bodies, and a handgun was recovered at the location. Roecker lived at the home, according to authorities.
Roecker and Koranda were previously classmates at Lourdes High School in Rochester. Koranda was a student at the University of Minnesota at the Twin Cities campus. Roecker attended the University of Minnesota Duluth.
Mueller said it doesn't appear the two were romantically involved.
"They were friends, acquaintances; we are still in the process of gathering more information as to the relationships," Mueller said.
The Bureau of Criminal Apprehension is assisting the Olmsted County Sheriff's Department in the investigation.
Additional details have not been released.
