It also helps to show that the accused was in possession of Telstra pants.

This comparison helps to show that the fibres from the pants are transferable and could have transferred to the victims. The fibres from the Telstra pants were shown to have corresponded to the fibres found on the victim of that attack. In order to link the clothing fibres to the accused, the prosecution linked the fibres from an attack that Edwards had pleaded guilty to. It is important to note that the accused was a Telstra technician who owned and wore items of Telstra clothing during the time of the murders and attacks. The prosecution argued that these clothing fibres found originated from items of clothing made for Telstra technicians. The clothing fibres that were found were blue polyester fibres and blue non-delustered rayon fibres. The scientists considered the two fibres to have consistent spectrum profiles. To further show that the two fibres corresponded, the scientists produced a Microspectrophotometry (MSP) spectra of both fibres showing the similarity of the two graphs. During a comparison microscopy of a control fibre from a 1996 VS Holden Commodore and the trace fibre, they found that the particular fibres did vary slightly, however they considered them to correspond. The fibres correspond to properties of a set fabric from a 1996 VS Holden Commodore. The ChemCentre scientists identified a group of 20 grey polyester fibres in Jane Rimmer’s hair mass. This database is comprised of fibres associated with the victims and fibres collected from various materials, mainly carpets and fabrics found in cars. The car fibres were initially compared in a database created by ChemCentre. The two kinds of critical fibres found were ‘clothing fibres’ and ‘car fibres’. Crucial fibres were referred to by the court as fibres that were found on the victims. The Fibresįibre evidence was the other crucial evidence that helped to link the victims to Edwards. The only other time the kimono was tested was in 2016 and as DNA can not persist that long in a laboratory it was excluded as a possible source of contamination. The Kimono was another contested source of contamination, however, the lab that did these examinations on the kimono, PathWest, submitted evidence that the kimono was examined on Mabut no samples were taken and thus was returned to the police on March 30 1988. However, the prosecution argued that although that may move DNA from one part of the body to the other, there was no reasonable explanation that Edwards' DNA was there in the first place. For example, the scissors used to cut the nails were placed on a ladder and were not cleaned in between cuts. The possibility that the accused DNA was introduced under the fingernails of Ciara Gleeson at the scene was proved non-existent as it was proved that there was no alternative source of DNA belonging to the accused at the scene.ĭuring cross-examination points about the awareness of trace evidence in the lab.

As Edwards had already pleaded guilty to the attack involving the kimono, prosecution linked the DNA profiles found on both the kimonos and the fingernails, to prove beyond a reasonable doubt that the DNA belonged to Edwards.Īs is with most DNA evidence submitted at trial, the prosecution had to prove the DNA evidence that their case so heavily relied on was not contaminated. The bodily fluid on the kimono was tested in 2016 and matched that of the accused Edwards in a sample that was taken from him at the time of his arrest. The DNA extracted from fingernails was a mixed sample, however they found that the mixed sample included DNA that was consistent with the DNA of the accused to a high degree of probability. In the case of the murders, DNA was discovered under the fingernails during the post-mortem examination of Ciara Glennon’s body in 1997. There were multiple points of DNA on the kimono, mostly body fluid, that could be linked to the accused. Edwards pled guilty to this attack and 4 others on October 21 2019.

The kimono was originally seized in 1988 at a crime scene in Huntingdale where the accused broke into a house and attacked the young women living there. DNA and fibre traces were the two main types of forensic evidence that appeared in this case. The forensic evidence in this case was heavily relied on in court by the prosecution.
