I just discovered the thread you were discussing the disappearance of Australian nuclear scientist Lachlan Cranswick from Deep River, Ontario — In case you are interested, here is one thread (of three other threads) about missing nuclear scientist Lachlan Cranswick. I just came across your thread today, and am curious if any of you have any new theories about this mystery.
Thanks, I have no theories except that too many of these disappearances go past coincidence.
