HARRISBURG — State police on Friday searched the hard drives of three state Senate computers issued to state Sen. Jane Orie amid an investigation into alleged document-tampering related to her mistrial this year on corruption charges.

According to the warrant approved by Dauphin County Judge Richard A. Lewis in Harrisburg, the hard drives were from a laptop computer and two desktop computers — one each from Orie’s offices in suburban Pittsburgh and her office in Harrisburg — used by Orie herself.

The computers were searched in Harrisburg because they’re no longer used by Orie. Rather, they have been kept in a locked room by Senate Computer Services at the state capitol at the behest of the Republican caucus, which is cooperating with the investigation.

The computers are being searched for evidence that Orie — or someone using her login “PASEN/jorie” — scanned and then deleted versions of documents used to defend her at trial, including some documents deleted or changed after the Allegheny County prosecutors subpoenaed the computer records in April.

The documents include one that Allegheny County Judge Jeffrey Manning deemed to be a “cut-and-paste” forgery and prompted him to declare a mistrial in March, while a jury was deliberating corruption charges against Orie, 50, and her sister, Janine Orie, 57.
