Here's the surveillance video from the Isaac Kolstad beating that had Mankato, Minnesota police chasing after a second suspect...
The suspect in question was arrested Tuesday.
21-year-old Trevor Shelley is now thought to be that suspect, but it's not known if Shelley was the one who punched Kolstad before Philip Nelson allegedly kicked him while he was on the ground. Nelson's attorney maintains his client was not the aggressor in the assault.
Nelson is facing two felony assault charges and is out on $20,000 bail.
Rutgers University head football coach Kyle Flood announced Tuesday Nelson has been dismissed from the team and that the university's thoughts and prayers are with the Kolstad family.
The most recent post on the Kolstad-created CaringBridge page came early Tuesday afternoon:
Isaac had surgery early this morning. It went well. Isaac remains in critical condition.
Please keep Isaac and all involved in your prayers.
