Not yelling but LE can't arrest and charge someone to bait and switch their actual suspect. They surely know a lot that we don't, but he is who they are certain did this. Maybe there will be others who get hauled in for protecting him or lying (maybe not), but he said himself he grabbed her and he left her dead in the cornfield, then he proved the latter is true by taking them to her.
This has happened in the past through. The Memphis 3. They were sentenced and put in jail for a crime they did not commit.
