Deputy Sean Street, 37, was fired after a internal review board hearing, according to a news release.
Street, who had been on the force for four years, had been suspended with pay before the review board, Strength said.
The sheriff said an internal investigation had been launched after Street’s name came up in another operation the department was conducting with the Internal Revenue Service into cases of identity fraud and false tax returns.
Investigators determined that Street had been collecting names, addresses, and Social Security numbers of people and supplying those names to another person suspected in a tax fraud scheme.
Investigators have not determined whether any of the names collected by Street were used to file false returns, and Street has not been charged with a crime, Strength said.
He said the sheriff’s office is continuing to work with the IRS in the investigation, which he expected to result in indictments.
He declined to elaborate or supply more details about the investigation.
Strength said a second sheriff’s employee who had been on suspension with pay during the investigation has been cleared and returned to work.
