No....it's not available within my library network. I checked the other day.
What I would say though is unless AS knew SJL personally, and she told him so, then it is hearsay and hence not reliable.
If friends/family told AS so, after SJL went missing, then it may carry some weight, but only if they told him independently of each other, without prompting or as a response to leading questions.
This I fear is how we are fed so much 'information' that is stated as fact, when it is just not the case and therefore it cannot be relied on in any way to advance an investigation.
I think it is highly unlikely, given the passage of time, that anyone is going to reveal key evidence that will help to solve this tragic case. I cannot begin to imagine the lifelong anguish when a loved family member/friend disappears without trace.
The greatest hope is that a body is found and identified by DNA/dental records as Suzy. This may not solve the case, but at least she can be brought home and laid to rest properly.
