The former top elected African-American official in Prince George's County, Maryland, has been sentenced to more than seven years in prison and fined $100,000 after pleading guilty to federal extortion and evidence-tampering charges

Jack Johnson, who served eight years as county executive, was arrested in 2010 after after FBI agents monitored a phone call in which Johnson and his wife, Leslie, discussed quickly getting rid of evidence. Johnson instructed his wife to flush down the toilet a $100,000 check from a developer and to hide nearly $80,000 in cash in her bra. Female agents say that they discovered the cash. A federal grand jury indicted Johnson on a series of charges including extortion, bribery and evidence tampering in February 2011. Johnson must serve three years on supervised release after an 87-month prison term, a law clerk for U.S. District Judge Peter Messitte said. The African-American must pay $30,000 by February 2012 and the remainder of his fine in $2,000 monthly installments starting after his release from prison, the clerk said.
