A guilty plea was accepted Wednesday from a man who joined former Gophers quarterback Philip Nelson in the severe beating of Isaac Kolstad after bar closing time in downtown Mankato nearly two years ago.
Trevor S. Shelley, 22, of Mankato, admitted to first-degree assault in Blue Earth County District Court. A lesser felony count of third-degree assault was dismissed. A jury trial had been scheduled for Monday.
As part of the plea agreement, Judge Bradley Walker will stay any potential prison time — up to 10 years was possible — and sentence Shelley to "up to a year of local incarceration," said County Attorney Patrick McDermott. Sentencing is scheduled for May 13.
Shelley, a high school classmate of Nelson's at Mankato West, was charged in May 2014 in connection with the attack on Kolstad around 2 a.m. on a downtown street. Nelson shoved Kolstad after mistaking him for a bouncer who had kissed his girlfriend.
Kolstad then knocked Nelson to the ground, but as Kolstad walked away, Shelley punched Kolstad in the head. Video shows Kolstad falling and smacking his head on the pavement. Nelson then kicked a prone Kolstad in the head.
While pleading guilty, Shelley acknowledged that it was his blow to Kolstad's head that satisfied the legal standard of inflicting "great bodily harm."
"Alcohol-fueled decisions … drastically changed lives for years to come," McDermott said after Shelley's admission in court.
Nelson, 22, was sentenced in March 2015 to 100 hours of community service after pleading guilty to fifth-degree misdemeanor assault. Nelson also was sentenced to two days in jail, with credit for two days already served. Felony charges that could have sent him to prison were dropped.
