A Rockville man admitted in federal court Wednesday that he helped defraud banks of more than $188,000 in a check-kiting scam, federal prosecutors said.

Cal Dennis, 32, who pleaded guilty in the District’s federal court to conspiring to commit bank fraud, faces between 21 and 27 months in prison under federal sentencing guidelines. He is scheduled to be sentenced in November.

Federal prosecutors said that Denis and others conspired to target nine banks in their check scam, which lasted from June 2009 through June 2011.
