I agree with part of your post, but I'm puzzled why you are include CT?
It's true others were innocent, and found guilty, but most all of those cases they were found guilty due to either faulty eye witness testimony or LE did not have irrefutable DNA back then linking the suspects to the crimes committed against their victims.
That simply is not the case with CT. Imo, less, and less people who are innocent will be found guilty, and actually more, and can be excluded now.
LE/DA has more than sufficient evidence to prove this case BARD if he had not taken the cowardly way out, and stood trial. If he was innocent he certainly had a choice to exercise his constitutional right to a fair trial.
Imo, he didn't because he knew they did have all the concrete evidence where a jury could find him guilty BARD. He knew it was just a matter of time, and he was living on borrowed time. He also knew it was very likely if convicted he would also receive a sentence putting him on death row.
They already had what they needed to arrest, and charge him, but like any murder investigation more, and more evidence would be discovered by LE.
In the articles I've read when the police was answering questions, I'm glad to see they are going to continue to investigate CT to see if he was involved in other unsolved cases.
They are able to do so now due to having his DNA profile which he left in Faye's case.
