CHESTER, Maine — The man shot and killed Saturday during a standoff with police in the woods off Route 116 was identified Sunday as Shad Gerken, 34, of Woodville.

Three members of the State Police tactical team involved in the shooting have been placed on administrative leave with pay, which is standard procedure following a police-involved shooting, according to Stephen McCausland, spokesman for the state police.

Sgt. Nicholas Grass, Sgt. Donald Shead and Detective Gregory Mitchell have been placed on leave while the Maine Attorney General’s Office investigates the incident to determine if the officers’ use of deadly force was justified.

Grass is the tactical team commander and a 19-year veteran of the state police, McCausland said. Shead has 26 years of experience and Mitchell has been on the job for 13 years.

The game warden who suffered a superficial cut on his left hand as he attempted to restrain Gerken earlier in day Saturday is Sgt. Ronald Dunham.

Investigators returned to the scene Sunday to gather evidence, McCausland said.

The incident began when deputies with the Penobscot County Sheriff’s Office responded to a 10:09 a.m. report Saturday of a man with a knife walking down Route 116 and acting erratically, Sheriff Glenn Ross said Saturday afternoon.

Gerken held police at bay from midmorning until about 6 p.m. when he was shot, according to a previously published report.

State police negotiators responded and attempted to talk to the man. Members of the tactical team also were called to the scene, according to a press release McCausland issued Saturday night.
