Ex-QLD detective played key role in search for those who betrayed Anne Frank’s family

Brendan Rook left the QLD police service to become a war crimes investigator for the ICC. The team spent five years combing through evidence

THE COLD CASE investigative experience of a one-time Queensland cop has proven critical in the international effort to pin down who betrayed Anne Frank's Amsterdam hiding place to the Nazis.

The team spent five years combing through evidence in a bid to unravel one of World War II's enduring mysteries, and last month revealed the name of the person they believe was most likely responsible.

The cold case team's findings were outlined in a new book called The Betrayal of Anne Frank: A Cold Case Investigation, by Canadian academic and author Rosemary Sullivan.

Former Queensland homicide detective Brendan Rook came to the Anne Frank team while he was tracking war criminals for the International Criminal Court (ICC) in The Hague.

As a homicide detective in Queensland, Mr Rook had worked on the 1970 Mackay sisters murders investigation and was on the team that arrested serial killer Leonard John Fraser.
