Claremont trial: Graphic video of corpse examination shown in court

Another distressing and graphic video has been played in the Claremont serial killings trial, showing how police handled one of the crime scenes.

Ex-Telstra employee and confessed rapist Bradley Robert Edwards, 51, denies murdering Sarah Spiers, 18, Jane Rimmer, 23, and Ciara Glennon, 27, in 1996 and 1997.

During his second day of testimony in the Western Australia Supreme Court, former forensic supervisor Robert Hemelaar narrated an hour-long video of the examination of Ciara Glennon's body where it was found in bushland at Eglinton, north of Perth, in April 1997.

Justice Stephen Hall previously ruled such sensitive footage should not be viewed by the public gallery, so only the audio could be heard with the screens concealed by a large board.

Outlining the scene in the footage, Mr Hemelaar said bark on a tree appeared to be damaged, as well as some vegetation covering Ms Glennon's feet area.

"It appears twigs have been torn from the trees," he said.

"We've now removed a portion of the vegetation, we are seeing the deceased person ... now panned to the shirt, head area, and we are now panning down (to the) waist, bottom, left thigh."

Mr Hemelaar said Ms Glennon was clothed, lying on her stomach with her left arm out, her left thigh slightly higher up and her right arm underneath her.

She was also wearing jewellery, including a bracelet and watch.

Prosecutors allege Edwards' DNA was found under or on her fingernails.

"The nail on the ring finger is short, I don't know if it has been broken ... it's shorter than the others," lead forensic pathologist Karin Margolius is heard saying in the video.

At one stage, a male voice is heard saying: "Have you got clean gloves?"

Another man replies: "Yeah, I've got some here."

Officers also collected insect material for testing.

Ms Glennon was later lifted by a plastic sheet into a body bag, then temporarily placed in the shade.

As the video was played, Edwards sat in the dock and at times took notes or twiddled his fingers.

Ms Glennon's father Denis, who has attended much of the trial, continued to sit in the public gallery as the video was played.

The public gallery was allowed to view some photographs from the crime scene that were not deemed to be sensitive.

Mr Hemelaar is yet to be cross-examined.

The court previously heard Ms Glennon had neck injuries consistent with a sawing action.

Prosecutors also allege fibres found in Ms Glennon's hair and on her shirt matched Edwards' Telstra-issued work clothes and a car he had access to at the time.

The police handling of the crime scenes is central to the case because the defence claims contamination is an issue.

Several police officers previously testified they stayed metres away from the bodies.
