MANKATO — A second man sought in connection with a downtown beating that left a former Minnesota State University football player in grave condition has been arrested.
Trevor Stenner Shelley, 21, of rural St. Peter was arrested Monday night.
Mankato police received numerous tips about the Sunday morning assault. A segment of surveillance tape of the scene was released to the public Monday afternoon to help identify the unknown suspect.
Shelley was booked into the Blue Earth County Jail Monday night for the same charges Philip Nelson, 20, is facing, which are first- and third-degree assault.
Surveillance videos not released to the public allegedly show a man now thought to be Shelley knocking 24-year-old Isaac Kolstad to the ground with a punch to the face, police said. Nelson, a former quarterback at West High School and the University of Minnesota, is then seen kicking the head of an unconscious Kolstad, according to a criminal complaint charging Nelson.
Occupants of the white vehicle in the publicly released video also came forward. Police are still looking for additional witnesses and others with knowledge about the whereabouts of the involved parties throughout the hours preceding the incident.
The man police suspect was Shelley can be seen running east down Front Street after the assault. Shelley's Facebook page says he lives in St. Peter, and he was a 2011 graduate of Mankato West High School. Nelson graduated from West in 2012.
Mankato detectives were assisted by Le Sueur County sheriff's deputies and the Minnesota Bureau of Criminal Apprehension when they arrested Shelley at his house at 44294 Hillside Court at 6:15 p.m. Monday. The house is across the river from St. Peter in Le Sueur County near the Shoreland Country Club golf course.
Kolstad remained in critical condition Tuesday at Mayo Clinic Health System in Mankato. His father, Blaine, said on a CaringBridge journal that Isaac had undergone surgery and it went well.
