JC was 17 christmas 81 not 16.I have not been able to verify this but it's worth noting that in the WIKI entry for Chris Dawson the police have charged him with sexual relations with a child with age between 10 and seventeen. Which is to stay they aren't sure that they can prove age sixteen. However if what MD said, which I am sure she won't repeat in any carnal knowledge trial, that CD and JC were sleeping together over the xmas at the end of 81, then that makes her 16 which carries a much higher penalty (Teacher and pupil relationship) .
One other matter with respect to this . LD was intoxicated in some way the night she went missing. I'm sure in one of HT's podcasts it is mentioned that CD had done this to LD before , so that he and JC could have sex under his roof. Either HT made that up or JC stated that at some point - possibly in one of the coroner's inquests. JC is not well known for telling the truth.
BUT....we can prove she and CD where in a committed relationship starting sometime in 1980 which does confirm her to be 16 when he told her he was hers forever or to that effect.
I haven't seen anything to suggest JC a liar?
Can you extend on what you believe she isn't telling the truth about?
