Prosecutors say they're reviewing whether Kankakee County should revoke the pension of a former sheriff's deputy convicted of fraud.

Kankakee County State's Attorney Jamie Boyd tells The Kankakee Daily Journal that his office is reviewing Timothy Swanson's case. Swanson was sentenced in May to more than two years in federal prison for mail fraud, money laundering and tax evasion.

Swanson previously was police chief in the Chicago suburb of Countryside. That city's police pension board has revoked Swanson's $101,000 annual pension. He will receive personal money contributed to his pension but no public money.

Prosecutors say Swanson created a tax-exempt organization to operate two helicopters for law enforcement. Officials say he asked for contributions, which he then spent on personal purchases.

Swanson pleaded guilty to the counts in January.
