The memorial honoring Nathan Desjardins was held Friday at the Augusta Civic Center.

The 20-year-old Fryeburg officer suffered a head injury when the boat he was riding in hit a submerged object May 27 during a river rescue. The body of the missing canoeist was recovered four days later. Desjardins died June 6 at a hospital in Lewiston.

The Maine Warden Service says Desjardins' death is the state's 85th law enforcement death in the line of duty.
