CHARLESTON, W.Va. -- Authorities said a former Glasgow police officer and another man invaded a Smithers home dressed as State Police troopers on Monday night.The former Glasgow policeman, Donald Scott Wills, 43, of Smithers, was arrested and charged with first-degree robbery Tuesday, Smithers Police Chief Gerald Parker said. Parker said Wills and another man went to a home along Michigan Avenue in Smithers wearing State Police jackets and carrying fake badges and non-working handguns. The men identified as State Police troopers and told the homeowners they needed to come inside to speak with them, he said. The two men then ordered the homeowners to the ground and tied them up, Parker said, then began looking for drugs and cash.Eventually, Parker said, police were notified of the commotion. Smithers officers arrived as the two men escaped on foot. The officers, assisted by Fayette County sheriff's search dogs, failed to locate them.Investigators discovered on Tuesday that Wills was allegedly involved. Wills was arrested at his home and was to be arraigned Tuesday afternoon in Fayette County Magistrate Court.The search is still on for the second man, who also will be charged with first-degree robbery, Parker said. He did not name the second suspect.Wills was fired as a Glasgow police officer in April after allegedly buying drugs from a confidential informant.The informant told sheriff's deputies that Wills bought drugs while in uniform and driving a Glasgow city police car, according to a criminal complaint filed in Fayette County Magistrate Court.Deputies set up a sting operation at the informant's home and the informant called Wills at the Glasgow Police Department and asked him if he would come over to buy drugs, according to the complaint.Wills allegedly came later, in street clothes, and bought 30 oxycodone pills for $30, offering to pay the rest of the money owed for the pills once he sold them, Fayette County Sheriff Steve Kessler said.Wills was arrested and charged with possession of a controlled substance with intent to deliver, a felony. He was indicted by a Fayette County grand jury on the charge in September.Reach Travis Crum at firstname.lastname@example.org or 304-348-5163.
