The Washington State Department of Transportation (WSDOT) has asked the Washington State Patrol and Pierce County Prosecutors Office to investigate a former WSDOT employee for allegedly scamming the state for $67,000 in unearned overtime over the last two years.

According to WSDOT spokesman Lloyed Brown, WSDOT has been reviewing its budget and closely examining overtime when alterations to timesheets showed up. The female employee—who had worked for the department for four years—accused of altering her own time sheets has resigned and Brown says WSDOT has referred the case for criminal prosecution and is also seeking a "civil penalty and restitution with interest."

Brown says the department is continuing its audits but hasn't turned up "any other irregularities."
