From the post Gazette July 11 1999''

Contacted on the day before his retirement from over three decades with the Pennsylvania Game Commission, Law Enforcement Bureau Director, Dick Fagan said, "There has not been a confirmed wild mountain lion sighting in Pennsylvania in my 34 years with this agency. But that doesn't mean there isn't one out there. I've been around wildlife too long to ever say never." \
