KERRICK — Authorities are searching for a missing duck hunter who was last seen in a northern Pine County lake.

Authorities believe the man fell out of the boat and wasn’t wearing a life jacket.

About 30 people from multiple agencies searched for the man Thursday. The search is expected to resume Friday morning.
