Judge Christopher Gee found Mattison guilty, ordered a pre-sentence investigation and set sentencing for Aug. 27.

The charges stem from the Feb. 24, 2017, death of James Lennon, 33. Sheriff’s deputies said they responded to his home north of Troy and found him not breathing. A woman at the residence also overdosed but survived.

Also charged in the death was former West Milton resident Derek T. Gardner, 33, now of Sidney. He earlier pleaded to charges of attempted corrupting of another with drugs, a third-degree felony, and one count of aggravated trafficking in drugs.

Gardner’s sentencing is scheduled July 23.
