ST. CLOUD, Minn. (AP) -

A judge has certified a 17-year-old boy to stand trial as an adult in the death of a college student who was punched in a St. Cloud alley.

Prosecutors have charged Jesse Jean Smithers of Sauk Rapids with second-degree murder, first-degree manslaughter and first-degree assault.

Smithers appeared in adult court Monday. A judge set unconditional bail at $1 million or conditional bail at $500,000.

A complaint accuses Smithers of jumping out of a car on Sept. 20 and punching 20-year-old Colton Gleason once in the face.

Gleason fell backward and hit his head. The Minnesota State University, Mankato student later died.

The St. Cloud Times reports Smithers has denied having anything to do with the attack on Gleason.

A message left for Smithers' attorney was not immediately returned Monday.
