[[Oscar Guerrero]] was a freelance journalist from [[Colombia]]. He met [[Mordecai Vanunu]] in [[Sydney]], [[Australia]], where Vanunu was sharing top-secret photographs of [[Israel|Israel's]] nuclear facility.[^1]

Guerrero saw the photographs and proposed publishing them for a fee. He first approached *The Sydney Morning Herald*, but the photographs were rejected. His approach was, however, passed on to the [[Australian Security Intelligence Organization|Australian Security Intelligence Organization]] (ASIO) and then to the [[Australian Security Intelligence Service|Australian Security Intelligence Service]] (ASIS), who informed Israel.Guerrero then tried *The Age* newspaper in [[Melbourne]], and later the [[London]] papers.[^1]

[[Nicholas Davies]], a London *[[Daily Mirror]]* foreign editor and Israeli agent, stalled Guerrero by telling him the newspaper needed an expert to check his claims. Guerrero had already struck a deal with *The [[The Sunday Times|Sunday Times]]* to publish Vanunu's story and photographs, with Vanunu receiving a £250,000 advance on a book and Guerrero receiving a 10% cut. Guerrero approached the *Mirror* because he believed he was being cut out of *The Sunday Times* deal.[^1]

A hotel register at the [[Eccleston Hotel]] in London recorded a Cheryl Hanin as a guest just before Guerrero checked in. [[Peter Hounam]] of the Sunday Times found the entry while tracing the woman who had lured Mordecai Vanunu from London. The form gave a Florida family address and the nationality "USA."[^2] She is profiled on the page for [[Cindy Hanin Bentov]].
