Unless we get access to the police records, I don't think we can know. I can tell you I was one of the 3 closest neighbors, and the police never came and asked me any questions. That has always struck me as odd. (why I keep mentioning it here)
I dawned on my when I read the July 2001 article in the Omaha World Herald, that JJ did have a close relationship with Rev. E.V. I don't buy into all of the stuff with dates and numerology, but if his parents bothered to mention that the priest and Jason had discussed priesthood, and Jason had looked into a seminary in St. Louis, that the two had been in contact with each other on a regular basis. This contact is more frequent than any we have established so far with JJ. Remember, he is a loner. We haven't uncovered even a best friend, let alone GF, or work buddies.
The Rev. E.V. does not show up on the list the archdiocese recently released of clergy sex offenders in the Eastern Nebraska area, but I suspect only 1/2 of them have ever been exposed. I spent 12 years in Catholic schools, and never experienced any sort of thing, but I read about it frequently these days. Recently Omaha seems to have an epidemic of woman teachers getting caught with underage boys, but the priest thing is always creepier because those men are placed in a sense of "power", and an offense is quite confusing to the victims.
He was a missionary priest, so his movement around the world does not alarm me. When I was young, I had a priest approach me about the priesthood. I was not interested though. Nothing wrong with any of that, but E.V. is as suspect as anyone. (All of Omaha is suspect?)
