Former Prince George's County Executive Jack Johnson after he pleaded guilty to federal corruption charges in May.
Prosecutors have released audio recordings of conversations between former Prince George's County Executive Jack Johnson and his wife, Leslie Johnson shortly before they were arrested at their Mitchellville home on federal fraud charges in November of 2010.
The tapes, which were made public for the first time this week, document a conversation between the Johnsons as FBI agents were waiting outside the house to serve a search warrant.
On the call, which was documented in federal charging documents, Jack Johnson instructs his wife to find a check in their bedroom and flush it down the toilet. They then discuss cash also hidden in the home, and Jack Johnson instructs Leslie to "put it in your panties and walk out of the house."
Jack Johnson was accused of running a "pay-to-play" scheme with business interests in the county, and last spring he pleaded guilty to two counts of extortion, evidence and witness tampering. He is expected to be sentenced Dec. 6.
Leslie Johnson pleaded guilty to a felony charge of destroying evidence in June, and shortly after resigned her Prince George's County Council seat. She is expected to be sentenced in the coming weeks.
