A man accused of punching a former Minnesota State, Mankato, football player in the head and knocking him to the ground is free on bail.
Police arrested 21-year-old Trevor Shelley of St. Peter on Monday, hours after they released surveillance video showing a man in a red shirt running from the scene in downtown Mankato. According to the criminal complaint filed Wednesday, witnesses identified Shelley as the man suspected of punching 24-year-old Isaac Dallas Kolstad and knocking him to the ground.
Shelley has been charged with both first and third-degree assault. If convicted, he faces up to 20 years in prison and $30,000 in fines on the first-degree charge and up to five years in prison and $10,000 in fines on the third-degree charge.
The complaint says Shelley told police that he didn't hit anyone.
A judge set his bail at $20,000. Shelley was released from jail Wednesday afternoon and had no comment. He is due back in court May 22.
Defense attorney Michael Padden said they'll argue self-defense.
Former Minnesota quarterback Philip Nelson is already charged with two felony assault counts; he allegedly kicked Kolstad in the head.
Kolstad's family said on its CaringBridge website that a surgery Kolstad had on Tuesday morning went well. He was still in critical condition as of Wednesday morning.
