THE FACTS
5A statement of agreed facts tendered by the Crown states the following:
"1. At about midday on Saturday 1 February 1992 two bushwalkers, on a track in the Royal National Park near Bundeena, found some personal effects (deodorant, underwear and other items) and then the naked body of a woman. She was later identified as Pia Navida, aged 39 years. The cause of death was head injuries apparently inflicted with a large, blood stained rock found lying nearby. A car tyre track at the location near the deceased was observed and recorded. The tread pattern has been identified as consistent with a Dunlop Le Mans tyre with specifications J2 70 P195/70HR14. This type and brand of tyre is able to be commonly fitted on HQ Holdens.
2. Ms Navida had last been seen alive at about 2.00pm on Friday 31 January, 1992. Post-mortem examination suggested the time of death as the night of 31 January to 1 February 1992. Various swabs were taken from the deceased's body, including from the vagina, and rectum, together with such samples as fingernails.
3. Subsequent investigation showed that Ms Navida, a Filipina, had for the previous 13 months been living a nomadic lifestyle, earning a limited income from prostitution and using drugs. She and a boyfriend, Wayne Taylor, had frequented a cafe known as "Greasy's" near Central Railway Station in Surry Hills. Ms Navida from time to time would purchase drugs from a person or persons dealing from "Greasy's" cafe. Taylor had stayed at a nearby hostel, Foster House.
4. Forensic examination of exhibits in 1992 found semen on the vaginal and rectal swabs taken from the deceased's body; unidentified DNA was found on the vaginal and rectal swabs.
5. From the early investigation the following matters arise:-
+ The area that the body was found is a remote location concealed from the roadway;
+ The location was a very long distance from the location the deceased frequented at the time;
+ The deceased worked as a prostitute but had options available to her in her usual locations to engage in sex acts with clients and there was no need for a client or clients to take her to such a remote location for paid sex acts;
+ She did not have a car and had to be driven by someone to the location;
+ The body was completely naked;
+ Part of her clothing and some of her personal items were strewn around the location where her body was found and at some other nearby locations;
+ Sexual intercourse had occurred with the deceased which included vaginal and anal penetration;
+ On the track, and near where a tyre track ends, the deceased was struck on the head with a rock causing her death and her body was dragged into the nearby bushes.
The combination of the matters enables the inference to be drawn that she was not at that remote location as a result of some agreement with a client. However it is consistent with the murder being sexually motivated which involved driving her to the location against her will and sexually assaulting her and then murdering her. The offender has a prior knowledge of the area.
6. Police continued to investigate. They interviewed Taylor and a number of other "persons of interest", but were able to eliminate all of these as suspects in Ms Navida's death. A Coronial Inquest returned an open finding on 6 December, 1994. The case remained unsolved.
7. Advances in DNA technology permitted further examination of exhibits in 2006 and thereafter. In 2006 such an examination of the rectal swabs identified thereon the DNA of the offender, Steve Matthews. Further testing in 2011 identified the DNA of Matthews on a vaginal swab, and that of co-accused Rodney Paterson on rectal swabs, a swab from the deceased's blouse in the area of the right breast, and on one of the deceased's fingernails. DNA of a male referred to as "unknown male A" was also identified in a rectal swab. Other items (fingernails, swabs, beads worn by the deceased) were examined and were now found to contain DNA from at least three individuals. It was found that the offender, Paterson and an "unknown male A" could not be excluded as the source of the male
DNA recovered. It was only on receiving the DNA results in 2011 that police had forensic evidence of the involvement of a third male.
8. DNA recovered from the deceased's fingernails of three individual males is consistent with her struggling with those persons prior to her death.
9. Police established that the offender and Paterson had been together in Queensland some six weeks after the date of the murder, as they had come to the notice of Queensland police at that time.
15. At the relevant time the offender's habit was to purchase drugs from a person or persons dealing from "Greasy's" cafe.
16. Nicole Duffin was in a relationship with Matthews, with some breaks in the relationship, from around the late 1990's to early 2000's. Nicole Duffin, states that he once told her that he killed a person (she thinks he said a male) in a bush area by bashing that person with a large rock which he had wielded with both hands (that is, in the same manner in which the deceased appears to have been killed). Whilst telling this to Ms Duffin, he demonstrated to her what he did.
17. Ms Duffin recounts an occasion where at the request of Matthews she participated in group sexual activity with him and another male. She also states that Matthews initiated anal intercourse. It can be inferred that at the time of the murder the offender had those tendencies. Taking into account that shortly after the murder he was in Queensland with his co-accused, the evidence establishes that the presence of the DNA of both accused and a third male from examination of the deceased and her clothing is the result of the offender acting on his tendencies so that in the presence of the co-accused and with another male they had sexual intercourse with the deceased including anal penetration.
18. Ms Duffin states that during her relationship with Matthews they went on picnics to Bundeena at his suggestion. In an interview with police on 18 July 2011 Matthews admitted that as a school age boy he would camp and fish in the Royal National Park. Accordingly as at the date of the deceased's death the offender was familiar with the road way off which the body of the deceased was located.
19. The offender's hairstyle at March 1992 had changed from the style he had in late 1991 consistent with an attempt to change his appearance after the murder out of a consciousness of guilt.
20. During the interview with Matthews on 18 July 2011 police informed him that his DNA had been located on a rectal swab from the deceased. He offered no explanation. He said that he had no memory of either the deceased or Paterson whenshown their photographs. In the interview and other recorded conversations he maintains a lack of memory due to a traumatic brain injury sustained on 9 October 2005. Dr Reid, clinical neuropsychologist, is of the opinion that the loss of memorydescribed by Matthews is not consistent with what would be expected from such traumatic brain injury.
21. Police enquiries of various intimates of the deceased indicate that she did not engage in anal sexual intercourse with her clients and that if confronted with physical threat she would fight back. This evidence is consistent with non-consensual sexual intercourse and that DNA under her fingernails from three males is as a result of her attempting to fight off her attackers.
22. Paterson was arrested and charged on 2 August 2011. Matthews was arrested and charged on the same day in Victoria and extradited to NSW.
23. The evidence establishes that on or about 1 February 1992 the offender together with two other males took the deceased in a motor vehicle, consistent with a HQ Holden, to bushland near Bundeena where they sexually assaulted her and thereafter each participated in the murder of Pia Navida which involved one or more of themstriking her with a large rock to her head causing her death. On the admission to Nicole Duffin the offender struck the deceased to the head with the rock located near the deceased."
6Three matters should be noted regarding the agreed facts. Firstly, I have reproduced them in the form in which they were tendered, and absent any paragraphs numbered (10) to (14). Secondly, notwithstanding the contents of paragraphs (17) and (23), the Crown made it clear that there was no suggestion that the offending referred to in the Form 1 was said to have been committed in company. Thirdly, I raised with the Crown what appeared to me to be some inconsistency between paragraphs (16) and (23), in that paragraph (16) purported to attribute the act of killing the deceased solely to the offender, whilst paragraph (23) suggested the involvement and participation of others. The Crown subsequently clarified that it did not assert that any person other than the offender struck the deceased, nor did it assert that any other person was present when this occurred.
7A report from Professor Duflou, Forensic Pathologist, was tendered by the Crown. Professor Duflou conducted a post mortem examination of the deceased and found that she had sustained the following injuries:
(i)a massive deformity of the head with crushing of the face and forehead;
(ii)a 34mm laceration immediately posterior and superior to the pinna of the left ear, with protrusion of fractured skull fragments and surrounding abrasion of the tissue;
(iii)a 12mm x 10mm laceration to the right of the forehead, 20mm to the right of the midline;
(iv)a 14mm laceration to the pinna of the left ear at its superior insertion;
(v)extensive abrasions of the forehead and surface of the head;
(vi)multiple linear abrasions over the superior aspect of the right shoulder, the posterior trunk and the posterior iliac crest, consistent with drag marks over a rough surface;
(vii)a 20mm laceration on the ulnar surface of the left thumb with associated degloving of the skin of the thumb but without any underlying fracture of the bones of the hands;
(viii)a 50mm x 30mm abrasion and contusion on the dorsum of the left hand, in the region of the first web space;
(ix)areas of abrasion on the dorsal surfaces of the fourth and fifth fingers of the left hand; and
(x)two areas of red bruising measuring 20mm x 15mm and 30mm x 20mm in the right antecubital fossa.
8Professor Duflou concluded that the head injuries sustained by the deceased were the direct cause of her death.
