WINDHAM, Maine — A local man was being held without bail Wednesday on a murder charge in the fatal shooting of a man who was trying to steal his marijuana plants, Maine State Police said.

Joseph Green, 44, was arrested at his mother’s home in Casco late Tuesday in the death of David Harmon, 41, of Windham. Harmon’s body was found last week at the base of an 8-foot ledge on Green’s property.

Harmon was reported missing Aug. 31 by his wife, who told police she had dropped him off at the corner of Land of Nod and Cole roads earlier in the day so he could scout hunting sites. But police said their investigation revealed that Harmon was on the property to steal marijuana plants that Green allegedly was growing.

Harmon and Green knew each other, police said.

An autopsy by the state medical examiner’s office showed that Harmon died from a “through-and-through wound consistent with a gunshot,” said police spokesman Stephen McCausland. His death has been ruled a homicide.

A handgun believed used in the shooting and some marijuana have been recovered, McCausland said.

Harmon’s wife was aware that her husband was searching for marijuana plants, but no charges have been filed against her, McCausland said.

Green was being held in the Cumberland County Jail and was expected to make a court appearance this week.
