HARRISBURG — A former high-ranking supervisor with the Pennsylvania attorney general’s office has resigned from his job in a county prosecutor’s office, the latest fallout from the disclosure that employees of the office swapped e-mails with pornographic images or videos.

Rick Sheetz, who led the criminal division until Attorney General Kathleen Kane took office early last year, resigned Monday from his part-time job as an assistant district attorney in Lancaster County.

District Attorney Craig Stedman said the e-mail scandal prompted Sheetz’s departure. Sheetz and his attorney did not respond to requests for comment.

Two other former prosecutors from the office, Chris Abruzzo and Glenn Parno, resigned from the Department of Environmental Protection last week after Kane released redacted copies of e-mails sent or received by eight former employees of the office. Abruzzo was the DEP secretary and Parno a department lawyer.

All worked for the office when Gov. Tom Corbett was attorney general from 2005 to 2011. Corbett has not been identified as a sender or recipient of the e-mails, which came to light during a review by Kane into how the office handled the Jerry Sandusky child molestation case.

Another former state prosecutor under Corbett identified by Kane, who later worked for Corbett in the governor’s office, has left the large law firm where he has worked for the past year. Chris Carusone said he was forming his own practice, but declined to discuss why he left Conrad O’Brien. The firm’s chairman, Jim Rohn, released a statement that wished Carusone well, but did not address the circumstances of his departure.

State Police Commissioner Frank Noonan, who also is one of the eight named by Kane, has kept his job.
