the list of suspects was progressively narrowed to a short list of 230, then to an even shorter list of 32. There were similar aspects to all the murders. Each of the bodies had been dumped in remote bush-land and covered by a pyramid of sticks and ferns. Forensic study determined that each had suffered multiple stab wounds to the torso, and many showed signs of sexual assault. The killer, probably a local with a 4WD, had evidently restrained and spent considerable time with the victims both during and after the murders, as campsites were discovered close to the location of each body. Matching .22 bullets, shell casings, and cartridge boxes from two weapons also linked the crime scenes. Speculation arose that the crimes were the work of several killers, given that most of the victims had been attacked while as pairs, had been killed in different ways, and buried separately. On 13 November 1993, police received a call from Paul Onions (24) in the UK. On 25 January 1990, Onions had been backpacking in Australia and, while hitchhiking from Liverpool station towards Mildura, had accepted a ride south out of Casula from a man known only as "Bill".

Onions flagged down Joanne Berry, a passing motorist, and together they sped off and described the assailant and his vehicle to the Bowral police. On 13 April 1994, detectives re-found the note regarding Onions' call and sought the original report from Bowral police, but it was missing. Fortunately, a constable had recorded details in her notebook. Onions' statement was corroborated by Berry, who had also contacted the investigation team, along with the girlfriend of a man who worked with Ivan Milat, who thought he should be questioned over the case. Arrest and trial On 26 February 1994, police surveillance of the Milat house at Cinnabar Street, Eagle Vale commenced. Police learnt that Milat had recently sold his silver Nissan Patrol four-wheel drive shortly after the discovery of the bodies of Clarke and Walters. Police also confirmed that Milat had not been working on any of the days of the attacks and acquaintances also told police about Milat's
