One of the so-called "burger boys" in the Claremont serial killings trial says he saw a woman leaning into a car to talk to the driver on the night Ciara Glennon went missing, while another man said he saw her get in.
Ex-Telstra technician and confessed rapist Bradley Robert Edwards, 51, maintains he did not murder secretary Sarah Spiers, 18, childcare worker Jane Rimmer, 23, and Ms Glennon, a 27-year-old solicitor, in the mid-1990s.
Troy Bond, one of three men dubbed "the burger boys" along with Brandon Gray and Frank McElroy, said they went to the Continental Hotel in the Perth suburb of Claremont on March 14, 1997, then bought food from Hungry Jack's around midnight.
"There was a female walking up Stirling Highway," the 45-year-old told the Western Australia Supreme Court on Tuesday.
"Brandon said to her 'you're stupid for hitchhiking' ... I just told Brandon to be quiet and let her go," he said.
"She stuck her finger up at the three of us."
Mr Bond said he only saw the woman walking and could not say if she was hitchhiking.
Mr Gray said he saw the woman "neatening herself up", continue to walk then extended her arm "in a motion, maybe hitchhiking".
He made a comment to her and she gestured for him to mind his own business, Mr Gray testified.
"She walked like someone you probably wouldn't let walk like that by themselves ... maybe intoxicated," he said.
Mr Bond said he looked up the road as the trio ate their burgers at a bus stop and saw the woman leaning into a white Holden Commodore station wagon, talking to the driver.
Ian Stanford, 54, was a passenger in a car driven by Lisa Mighall when he saw a woman getting into a white vehicle, which he said may have been a ute with a canopy.
"It looked to be in reasonable condition ... no writing on the side of it," he said.
"As we went past the back of the car, the tail gate was up and there was a person holding it up ... I couldn't understand why there was a girl or a lady ... and she was in the process of getting in the back.
"I remember saying to Lisa, 'after what's gone on in this area, I can't understand why someone would do that'."
Mr Stanford said he never saw the woman's face but she was wearing a white top and black skirt.
Several other people have said they saw a woman matching Ms Glennon's description walking alone, with two saying she was leaning against a light-coloured car.
Prosecutors allege Edwards abducted Ms Glennon in his white Telstra-issued vehicle.
The trial has now heard from the majority of civilian witnesses and is taking a break over Christmas until January 6.
The next lot of witnesses will be police and forensic officers, who attended the crime scenes where the bodies of Ms Rimmer and Ms Glennon were found.
DNA and fibre evidence will also dominate next year's hearings.
The trial is expected to finish before mid-2020 and Justice Stephen Hall will then likely reserve his judgment for months before handing down his verdict.
