Police investigate possibility Peter Falconio had enemies

Police have questioned friends and former colleagues of Joanne Lees and Peter Falconio in Sydney to see if he had any enemies.

Northern Territory officers hope to find out more about the couple's life while they lived there and if Mr Falconio had made any enemies.

Managers at a city bookstore, where Ms Lees worked for four months, confirmed police interviewed her ex-workmates.

NT Police Assistant Commissioner Of Crime, John Daulby, said: "It is an avenue of inquiry with regard to Peter, to see if he had any bad experiences, developed any enemies, that type of thing."

Police have also identified the man found stabbed to death near Stuarts Well, south of Alice Springs, as Stuart Rhodes, a 39-year-old from Adelaide.

Australian newspaper The Daily Telegraph says they are not publicly ruling out a link with the disappearance of Mr Falconio, but it is understood they don't believe the incidents are connected.

Police have received more than 50 calls from the public since the release of security video footage of a man fitting the description Ms Lees gave of the abductor.

But Mr Daulby said she had given a "negative response" on identifying the man as her attacker when shown still photographs taken from the video, as well as other pictures.
