I've been telling you there something weird about this case. This is the one we've been following all week where this kid was killed when he went home at lunch with his sister. Cops make and arrest and then today -- you never see this happen -- say they were wrong. To call him a "person of interest" means nothing. That's a made up term, and they are just using it here to cover there arses from too much bad press.
Edit: A commenter reminded me of my post below where the lady wrote on Facebook that the first guy that was arrested should have been executed immediately. Wonder if she is rethinking that.
