Yes, I misunderstood. I can't see the Rs suspecting FW and simply giving up on it. If they suspected, or LE suspected, the Rs would be relentless. Wouldn't anyone? Remember they sent their surviving child to FW's home that morning. Hardly something you'd do if you suspected him of killing your other child. The DNA didn't match FW, either. There were no prints or fibers linking him to the crime. While he did admit touching the tape, the suitcase and some broken pieces of glass, it doesn't seem that he raised anyone else's suspicions, and JR's "suspicions' were simply for the purpose of deflecting blame from himself and Patsy. That can't be the reason for the rift between the families.
