Malcolm Naden, the man wanted for questioning over the murder of one of his cousins and disappearance of another, has been sighted over the past weeks on the Mulga Dump. Superintendent Stan Single told The Australian newspaper the intelligence was strong enough to mount an operation, but Walgett police did not find him. Mr Naden, 31, from Dubbo has family in the Walgett area and a number of positive sightings had been reported to police, Superintendent Single said. "He may have been lucky and spotted police and done a runner, it's a fairly big area to cover," he said. Superintendent Single said Mr Nolan was capable of living in the bush in some sort of humpy or other dwelling. Mr Naden is wanted over the death of Kristy Scholes on June 22, and for questioning over the disappearance Lateesha Nolan. He is described as being of Aboriginal appearance, 177cm tall, 85kg, of medium build, olive complexion, brown eyes, shaved head and possibly a moustache or beard. Anyone with information is urged to contact Crime Stoppers on 1800 333 000.
