Toby was the only one missing when they watched the chase broadcast. Therefore my money is on toby because that was a pretty important part of the strangler timeline. The reason he could have been missing that day was because he might have been planting some evidence to frame George Howard Skub. Toby did, after all write crime novels and he talked about writing books about people planting evidence, so he probably knew how to do it. However the only thing that casts doubt on the Toby theory for me is that he was on the jury against the Scranton Strangler. The odds of him getting on the jury of the Strangler trial is so incredibly small. Like less 1% of a chance. The only thing I can think of is that maybe Toby somehow threatened someone and the jury was fixed, so he was able to go on just to make sure the “strangler” would be sent to jail. Half way through Toby might have started to feel regret about framing him and that’s why he felt so bad after the trial, he would always talk about how he sent an innocent man to jail. Maybe that’s because he knew George wasn’t the stranger. Also when Toby went to the prison, he said he would tell the Strangler he thought he was innocent, that might of been his way of saying he was going to confess to the strangler that he was actually the strangler. That might of been why George strangled him, because he was so upset that he was framed and put in jail over something he didn’t do.
