Regarding CJ, I think its a crime in itself for an innocent, elderly man with absolutely nothing criminal in his history, to have suffered all that unfounded accusation and humiliation.
I blame the police as well as the media, when they revealed the arrested suspect was aged 65, no name was needed it was like a red flag to a bull. Also his cars hoisted in full view of the media, arrested on suspicion of murder because of something he thought he saw, on a dark night. They released him in a few days, because they could find nothing at all against him according to a police source at the time.
Yet the real culprit was interviewed early in the inquiry and was ruled out. Wasnt his alibi checked thoroughly, he claimed later he was away at the time but neighbours saw him come home sometime after Gregg left. So it would have been known from the start that he was in the building the night of the murder, only a few yards away from Jo.
So CJ should sue them all, police, media, etc for they have destroyed what years he has left, causing him to uproot and put his very home up for sale.
Its enough to give the man an early heart attack, the prolonged ordeal will have probably taken years of his life.
