They say the foursome used countersurveillance devices to search the Rhoden properties to see where video cameras might be recording their own movements or picking up their sounds.
Eventually, they went shopping.
According to the documents filed in Pike County Common Pleas Court last week charging each of the four
Wagners with eight counts of aggravated murder and a host of other crimes related to the Rhoden family slayings on April 22, 2016,
they either bought or built what they needed to carry out their plan. The documents indicate they bought special shoes at Walmart and "brass catchers," specially designed bags that connect to a gun and collect the spent shell casings.
Prosecutors say they bought ammunition, gun clips and equipment to build their own silencers to muffle the blasts.
And it was that last bit of workmanship that investigators say proved key to their undoing.
During a news
conference announcing the charges Tuesday, Pike County Sheriff Charles Reader said the killers had made a mistake:
They had left behind pieces of the equipment they used to build silencers. And, after 2½ years of investigation,
the final break came Oct. 30: Authorities recovered a silencer.
No one would say how or where, but Ohio Attorney General Mike DeWine said that final piece of evidence was taken to the lab to be processed. Those results came back Nov. 7.
