Yes CT made a statement to police on 8th May 2007 and signed the transcript. I don't have the statement itself. But it is clearly referred to in the rog and part of its text is read out so certainly it exists. And BTW the date of CT's arrival was transcribed wrongly (by 28 days!) in that first statement. Just shows how it is possible for a date to be written down wrong even when the witness is not elderly, and even when there is no translator involved.
How do you know that ? Are you sure CT signed the missing (?) document ? It might have been just a note, it's not in the files. The transcripts of the rogs were the responsibility of the LC. In the case of Mr and Mrs Payne not of the files written statements, the LC PO transcribed a time obviously erroneous.
There's no lost in translation there.
You can't infer from a mistake in transcription that Mrs Fenn heard a child crying on the day that suits your theory (btw when would Mrs Fenn have gone out according to you ?)
Now the person whom Mrs Fenn called on the phone is hopefully still alive in PDL. You have no authority to ask the PJ to check whether your suspicion is based or not, but I think it would not really be invasive to send this person a letter with a question, especially if the justification is to exonerate totally someone.
