EDINBURG — The Maine Attorney General’s Office is investigating the use of deadly force by a police officer in Edinburg, a township between Old Town and Howland.

Major Gary W. Wright of the Maine State Police said authorities received a 911 call around 5:30 p.m. Tuesday from a man who was making “suicidal and homicidal” threats.

Trooper Chris Hashey and Penobscot County deputy Ray Goodspeed responded and were confronted by 54-year-old Warren Dome, who was armed with a knife.

Hashey shot Dome, who had to be transported by helicopter to Eastern Maine Medical Center in Bangor where he remains in serious but stable condition.

Hashey has been placed on administrative leave while the AG’s office investigates.
