Watson, 45, is serving a life sentence for the killing of Ms Hope and her friend Ben Smart in the early hours of New Year's Day, 1998. He has always maintained his innocence.

Gerald Hope met with Watson over nearly six hours and said, in a statement released this morning, that on several key points, Watson was either elusive, or had rehearsed his responses.

Mr Hope said Watson was silent, unemotional and disconnected when asked about crown evidence that the bodies were disposed in a sleeping bag.

He said Watson did not convince him of his innocence on four points, including his arrival time at Erie Bay and a sighting at Marine Head on the day of the killings.

Mr Hope also said Watson's art work, done not long after he was arrested, appeared to be the work of a disturbed person, who at the time had no respect for women and was living a dark fantasy where death was the currency of the day.

Watson's father, Chris, had hoped for a different outcome, but he said there was not much he could do about Mr Hope's views.

"Gerald has a position that he has to maintain anyway, it's victimhood. I commend him for at least having a mind open enough to talk to Scott.

"I mean Scott can answer these questions, I think he does reasonably well in the article."

Mr Hope and Watson had long sought a meeting but wanted North and South journalist Mike White to attend. A long legal battle with the Corrections Department ensued and White was eventually given permission to attend. Mr White had been covering the case since the disappearance of Ms Hope and Mr Smart and was well known to both parties.

The subsequent article was published yesterday in North and South.
