That's an interesting theory, but here's another one: It Was An Alien Who Beamed In And Out Of The House From His UFO, which explains why he was never seen or caught. Look... Beverly was one of my grandmother's favorite students. This case has been on our minds since 1964. After six years in uniform, my Dad became a Cleveland detective a year later in late '65. My grandmother spent the rest of her life prodding my father to solve this case. Either the killer was already hiding inside, or it was someone Bev trusted enough to let into the house. Problem is, she'd been paranoid all through the summer and fall because of unsolicited gifts, hang up calls, and a feeling that she was being watched. Now, considering it was teenagers involved in that drama, all those things might have had absolutely nothing to do with her actual murder. Yet because she was on "high alert," there was NO WAY she was letting the local priest into the house. A visit by him, announced or unannounced, would have struck her as being too bizarre. She may have let Roger in, even though he passed a polygraph, as unreliable as those exams are. Still, his prints didn't match those found at the scene. (Although, I'd like to see his DNA tested against the blood sample they have in this case.) If she let her killer in, there's only a couple of suspects to choose from, Roger being one of them. If the killer was lurking in the house, he must have been hiding in the basement, and followed Beverly up to her bedroom when he heard her go upstairs. The entire attack took place on the second floor. The rest of the house was devoid of any signs of violence. The motive was probably rape, which may not have occurred because the assailant was interrupted by the arrival of Bev's girlfriend knocking on the doors, side and front. This case is still very much solvable. All the possible suspects, still alive, are senior citizens today. Detective Horrigan thought he knew who the killer was, and had it been a priest, I doubt very much he would have kept that information to himself. It was 1964, not 1764, and any man within 30 miles was a viable suspect; Beverly's Dad, teachers, the milkman, clergymen, the letter carrier, fellow cops---Whomever! Had any of the evidence pointed to a priest, Horrigan's gloves would have come off, and he would have exposed the good father, and damn the legal consequences! No, if Horrigan was truly onto the killer, and his suspicions were correct, Bev was killed by either her current or ex-boyfriend. The ex was the one who moved to Israel shortly afterwards, and to my knowledge never returned to this country. Both were far more likely to have been involved than a local priest.
