A Washington State Patrol investigation into the former director of Island Transit didn’t uncover any criminal wrongdoing, the Island County prosecutor concluded.

But Prosecutor Greg Banks calculates that former Island Transit director Martha Rose was overpaid by nearly $7,000 as part of her separation agreement. He said the agency probably can’t do anything to recoup the money because the board of directors ratified the payout amount as part of the settlement.

Banks asked detectives with the State Patrol to investigate last fall after a report by the state Auditor’s Office identified discrepancies between Rose’s calendar and her vacation leave balance.

The Auditor’s Office analyzed the transit agency’s records after financial problems forced officials to lay off employees and cut bus routes. Rose eventually left under pressure from the public and the Island Transit board of directors.

The board approved a $106,000 payout as part of Rose’s severance package, which included $88,000 for unused vacation.

The state audit report, and the state patrol investigation, stated that Rose hadn’t reported many days of vacation time.
