On November 23, 2016 a number of stains on the kimono were tested and five days later a DNA profile was detected.

The link between the DNA profile and the unsolved alleged Claremont serial killings was made on December 1, 2016.

A DNA analysis document being shown on the court screens shows the profile was found to be more than 1.1 billion times more likely to have come from Mr Edwards than another other person.

The report also showed Mr Edwards' brother, Troy Edwards, was ruled out as a contributor to the profile.

Various testing of the kimono was carried out in the following months, with one reporting the DNA profile was more than 100 billion times more likely to have come from Mr Edwards than another person.

When arrested in 2016, Mr Edwards denied the crime and according to the prosecution "feigned disbelief" at how his DNA had been found on the kimono. He changed his plea to guilty in October 2019, shortly before his murder trial commenced.
