Riley died at the scene near Kinnickinnic River State Park after the boat he was on, with Puhalla at the helm, collided with rocky cliffs shortly before midnight.
A Hudson resident, Daniel Michael Schultz, 55, told investigators he gave Puhalla several warnings that the boat wasn't where it should be, the St. Paul Pioneer Press reported.
The charges against Puhalla, according to the Hudson Star Observer, include:
- homicide by intoxicated use of a vehicle (two counts)
- negligent operation of a vehicle
- causing injury by operating a boat while intoxicated (two counts)
