PCA Report paragraph 214. Title from David and Goliath p215.

214. Mr Karam alludes in his book to a visit to New Zealand by the ex FBI criminal profile expert, John Douglas, in July 1996. Karam made contact with him at that·time and part of an interview was recorded by the 60 Minutes TV programme. According to Mr Karam, that programme assisted to bring the issues of the Bain case even further under public scrutiny. Mr Douglas said in the interview that in his experience it was usually the father of the family that was responsible for this type of crime. Mr Karam also states in his book that Douglas, while looking at photographs of the killings, reputedly said to him when talking about Laniet "Whoever had the most reason to hate this girl is your likely killer.  Mr Douglas later spoke to various Police meetings around New Zealand. Officers at these meetings recall that Mr Douglas explained that he was approached on his arrival at the airport, made his comments and responded to questions based on information given to him and without having further information about the case or a detailed understanding of the investigation. Comments which qualified his answers [explaining how he was speaking generally as he had not read the file] were not published.
