Three people have been arrested after federal investigators said they were part of a plot to kill a Charleston-area woman for money.

The plot was exposed Friday when Charleston police pulled over Aaron Russell Wilkinson, 39, of Louisville, Ky., in a traffic stop, according to an affidavit filed in federal court Monday by an agent with the Bureau of Alcohol, Tobacco, Firearms and Explosives.

Police found a revolver and box of ammunition in the car, according to the affidavit. Wilkinson was arrested for driving with a suspended driver’s license. Wilkinson told police he was in Charleston because he was involved in a plot to kill a local woman for money, according to the affidavit.

The woman was targeted by Wilkinson’s former cellmate, Samuel Arthur Yenawine, 38, of Louisville, Ky. They had driven to Charleston previously and met with Yenawine’s ex-wife, Wendy Annette Moore, 37, who gave Yenawine money and pills to kill the woman with, according to the affidavit.

Wilkinson and Moore were booked into the Charleston County jail. Yenawine was booked into the Oldham County Jail in Kentucky.

All three were to be charged with conspiracy and travel in interstate commerce with the intent to commit murder and aiding and abetting, according to the affidavit.

Wilkinson and Yenawine were to be charged with possession of a firearm by a felon, the affidavit said.

The identity of the woman who was targeted for the hit has not been confirmed.
