BUFFALO, Minn. (AP) - A Minnesota man has pleaded guilty in a fight that led to the death of a former University of North Dakota student body president.

Twenty-four-year-old Alexander Tuomisto of St. Michael pleaded guilty Monday in Wright County to first-degree assault. A charge of second-degree unintentional murder is expected to be dismissed at his sentencing April 15.

The Grand Forks (N.D.) Herald reports that under a plea deal, Tuomisto will serve no more than five years in prison and pay no more than $20,000 in restitution.

Authorities say Tuomisto punched Adam Baker last May outside the Corner Bar in St. Michael, causing him to hit his head on the ground.

Baker was in a coma for seven months before dying in December at 32.

According to court documents, a defense attorney argued that Tuomisto was not the aggressor and was defending himself.
