Mr Powell has moved onto the two grey polyester fibres found in Ciara's hair mass known as VW1.

The state alleges the fibres originate from the seat inserts of a 1996 Holden Commodore VS Series 1 station wagon - the same make and model driven by Mr Edwards at the time of the murders.

The fibres are considered part of the 'grey polyester, group 1' which also includes 20 fibres found in Jane's hair.

Mr Powell said the two fibres from Ciara's hair were each compared against three fibres taken from different areas of Mr Edwards' former car and deemed to correspond.
