A district court judge sentenced a former Philadelphia prison guard to 48 months in prison Thursday.

George Kindle, 29, of Philadelphia, was convicted of delivering contraband to an inmate at the House of Corrections (HOC) in Philadelphia during the time he was employed there.

On two separate occasions in 2013, Kindle smuggled a cellular telephone and 100 pills marked as OxyContin past HOC prison security. Kindle was told he would be paid a $1,000 in return for the contraband, according to court documents.

In November 2015, Kindle pleaded guilty to two counts of attempted extortion and two counts of attempted distribution of controlled substances. U.S. District Court Judge John R. Padova ordered Kindle to pay a $2,000 fine and a seperate $400 special assessment fine in addition to his prison sentence.

Kindle was also ordered to three years of supervised release and 100 hours of community service.

Last month, a separate ex-prison pleaded guilty to similar charges, the Inquirer reported. John Wesley Herder was one of six correctional officers charged in a sting using prison informants to weed out contraband smugglers within the prison.
