You know, I was never sure who was lying, however, the more I hear the testimony and past statements, I am inclined to sayMM was not clear to anyone!!! I really think the Dr and his dad would have reacted much differently if he told them the sexual version!!!
Disclaimer: This is pure speculation.
Could have gone something like this:
Investigators: Mike, we are told you witnessed Jerry in the shower with a young boy. Is that true?
Mike: Yes.
Investigators: Is that all you saw?
Mike: Yes. I wasn't sure what I saw, actually.
Investigators: We are investigating Jerry because we have evidence that he is a serial pedophile. Was he abusing that boy in the shower?
Mike: He may have been. I'm not sure what was going on. I heard some sounds, and saw Jerry and a boy in the shower. It kind of freaked me out, so I slammed my locker and left.
Investigators: You didn't do anything to break it up?
Mike: No, other than slamming my locker.
Investigators: Mike, you witnessed a serial pedophile in the shower alone with a boy, and you didn't do anything to stop it? You could be charged with child endangerment! However, as the only eyewitness to Jerry's crimes, we can really use your help. Instead of being one of the bad guys in this story, you could be the hero........
