GUYS HELP ME.

So uhm, some little girl in my area got pregnant, and apparently, my brother is being framed! He said that he had never seen the girl or ever did the dirty with her and he also said that her parents had no proof that he did it, but my brothers jacket was under the bed and he was shocked, well, i was shocked, and the girl was saying it was my brother in a stupid little annoying voice, and i defended my brother saying he was home playing with his friends on his PS5, and her parents kept denying it. I asked if they had camera proof and they were really hesitant to show me it because it was private and inappropriate, but i told them if they didnt show me proof then they were lying, and the girl too. They never showed me the proof, well yes, it is very disgusting, but if they dont show me atleast like where they were preparing with their clothes on, im saying that they are lying and either it was a family member or some random dude. But what do you guys think?
