"The two prints were discovered June 4 — the day after Ryan resigned — on a shelf, 80 feet from where they should have been filed. Library officials said the prints were misfiled.

Despite the discovery, Evans said at the time the criminal probe would go on.

'The anti-corruption unit will continue trying to determine if anything else is missing,'Evans said. 'We will be examining what they have there. The investigation is not over.'

The police closed the case that same day without notice to the public."
