14 Inspection of the premises did not suggest robbery as a motive for the murder. There was no sign of forced entry to the house, and Mr Hutchinson's wallet remained untouched in his rear pocket. Police are aware of no other motive for the murder.
15 A Mr David Green had been in the general vicinity the previous day, 12 January, at about 11.30 am. Mr Green saw a male person fitting the general description of the plaintiff jump the fence at 74 Markham Street and run across parkland to a nearby creek.
16 Mr Green described this person's clothing as a dark-coloured long-sleeved top, possibly tracksuit, and dark coloured long pants, also possibly tracksuit.
17 Police also had reports of "numerous sightings" of a male on Rusden Street (which, later references showed, intersects with Markham Street) on 13 January. Some of these positively identified the plaintiff as the person. The description of the clothing he was then wearing was similar to that given by Mr Green of the clothing worn by the man he had seen the previous day. A significant addition to the clothing description was that the man seen on 13 January was wearing a cap described as "similar to a police cap".
18 On 17 January the plaintiff was detained by police. He was wearing clothes which fitted Mr Green's description of the clothes worn by the man he had observed, and "a dark blue/black cap". He was in possession of a pair of "fake handcuffs with a key and a butter knife". While he was in custody investigators noticed a high concentration of silvery-grey/white fibres on his socks. Subsequently, investigators discovered, near Mr Hutchinson's home, a clump of a plant, perhaps Patterson's Curse, that had similar fibres. Patterson's Curse is a plant which is not common in the area. One broken off plant was found in the area where Mr Green saw the person leave 74 Markham Street on 12 January.
19 The plaintiff's hair is, in length and colour, consistent with that found on Mr Hutchinson's shirt.
20 The plaintiff's mother lives in the near vicinity of Markham Street. The plaintiff has, on a previous occasion, given 1/75 Markham Street as his address, although there is, in fact, no such address.
21 The plaintiff was, after his apprehension, psychiatrically examined and, pursuant to the Mental Health Act 1990, found to be a mentally ill person; he was diagnosed as suffering from chronic schizophrenia. Although the precise nature of any order then made under the Mental Health Act does not emerge from the evidence, it is apparent that he was the subject of compulsory treatment orders under that Act.

23 Extensive medical records describe some of his history. These include many instances of the use of dangerous objects, threats of harm to others, aggressive and even homicidal thoughts towards various individuals. Most recently, in May 2006 he was found waving an axe at passing cars and passers-by, and in December 2006 to be loitering in the vicinity of school premises carrying scissors, a needle, with a tomahawk on the ground nearby.
24 A very large bundle of documents, containing drawings and writings by the plaintiff, was part of the material in evidence. This included a drawing of a headless torso; a reference to "Jack the Ripper"; a drawing of a hand ashing a cigarette; another depiction of a body with the head separated; an item which reads "by removing his head and then his Tom Thumb will be exposed"; and much, much more that would require an expert to analyse.
25 The medical records also showed that the plaintiff had been a long-term patient of the New England Area Health Service. He was admitted to a facility called Banksia House on 16 December 2006, although it is not clearly disclosed whether this was a voluntary or involuntary admission. In respect of this admission the nursing progress notes are extensive and comprehensive. They show that, at 6.30 pm on 7 January 2007 the plaintiff was unable to be located. Security and police were notified. The notes also record that, at 8.00 pm that evening, he had been seen by police but that police were unable to apprehend him. He remained "AWOL" until readmitted following his apprehension on 17 January.
26 Reports of the murder appeared in the media. Representatives of Banksia House contacted police to express their concern that the plaintiff, who was then still at large, may have been the perpetrator.
27 Investigators believe that DNA examination of the hairs found on Mr Hutchinson's shirt, the cigarettes found at the scene, a wrist watch worn by Mr Hutchinson, and the plaintiff's clothing, may provide evidence that suggests or establishes his presence at Markham Street on 12 or 13 January.
28 Detective Borghouts gave oral evidence and was cross examined. She expanded to some extent on her affidavit evidence; she said that the plaintiff's shoes, which had been seized on his apprehension on 17 January, bore red staining, and that preliminary testing was "presumptive for blood".
29 Detective Borghouts was also cross examined to suggest that her affidavit evidence, concerning the timing of the contact by Banksia House staff expressing concern about the plaintiff may have been inaccurate.
30 It is unnecessary to conduct a complete analysis of the requirements of the Act. That is because only two matters were challenged on behalf of the plaintiff. The first was the magistrate's finding that reasonable grounds existed to suspect that the plaintiff had committed the murder; the second, that there were reasonable grounds to believe that the forensic procedure(s) might produce evidence tending to confirm or disprove that the plaintiff committed the offence.
31 In the circumstances of the present case, it was necessary for the Magistrate to be satisfied of the following matters:
