It's then that things take a weird turn. Up until now, I've pretty much taken Gerry Koob, the former priest who had a close personal relationship with Sister Cathy, at face value. He seemed genuine, and sincerely affectionate toward Cathy. And he had an alibi witness, right? Rev. Pete McKeon went with Koob to have dinner and see "Easy Rider," then raced over to the apartment with him when Sister Russell called that night.
