A 22-year-old man was found guilty Monday for his role in an attack on a 24-year-old mentally disabled man in October 2008.
Jonathan Michael Diepold of Northfield will be sentenced in December after being convicted of charges including kidnapping, aggravated robbery and assault.
Diepold was one of five people charged in the incident in rural Dakota County, and is the last one convicted.
Prosecutors said Diepold was one of the primary perpetrators in the attack, in which the disabled man had to be hospitalized for his injuries.
The incident took place over two nights, as the man was lured to a rural area where he was accused of assaulting a girl and was beaten. On the second night, the man was able to make his way to a nearby road where a motorist picked him up and took him to a hospital.
Sentences for the others involved in the attack ranged from four days in jail plus community service work to eight years in prison.
