(a) The appellant and the deceased were in a relationship.
(b) During the afternoon and evening of 27 March, the appellant was at the deceased's residence. The pair drank alcohol and listened to music.
(c) Apart from the appellant, the deceased and A, there was no evidence that anyone else was present at the deceased's flat in the period shortly before the murder.
(d) Prior to 9:42 pm on 27 March, the deceased's mobile telephone was used to contact drug associates of the appellant who were not known to the deceased. Some of the communications concerned the acquisition of illegal drugs on credit ("on tick").
(e) The murder occurred at about 10:05 pm. A was in his bedroom (which was adjacent to the deceased's bedroom). He was wearing headphones and playing games on the Internet. When he had been playing "League of Legends" for about 20 minutes, he heard a scream that sounded like the deceased's voice and seemed to emanate from her bedroom. D, the person with whom A was playing "League of Legends", was verbally communicating with A while they played. D also heard a piercing scream about 20 minutes into the game. A computer examiner said that the game had commenced at 9:45 pm.
(f) About 15 minutes after he heard the scream, A heard a tap running in the kitchen. He then heard the side gate opening or closing.
(g) The deceased's injuries were consistent with the killer having used a cook's knife that was part of a knife block set that was kept in the deceased's kitchen. After the murder, the cook's knife was found to be missing. It was never located.
(h) The appellant's fingerprint was found on the fusion knife that sat within the knife block set adjacent to the usual position of the cook's knife. The fusion knife was not suitable for use as a stabbing weapon. Admittedly, the position of the fingerprint was also consistent with normal use of the fusion knife.
(i) When arrested, the appellant had a wound on the leading edge of his right index finger which was consistent with offensive knife injury.
(j) Consistent with the deceased attempting to defend herself against the appellant, the appellant's DNA was found under the deceased's right fingernails, her right forearm was injured and there appeared to be scratches on the appellant.
(k) The appellant's blood was found on the outside door handle of the deceased's bedroom and on the floor below the handle.
(l) A bag on the deceased's bed contained clothing that the deceased had purchased online. The bag had been delivered on the day of the murder. There was a bloodstained cut (or stab) on the bag. The blood contained the deceased's DNA. The cut was consistent with the weapon that had been used to kill the deceased. The appellant's fingerprints were on the bag.
(m) The appellant and the deceased were short of money. Earlier on 27 March the deceased had borrowed $50 petrol money from a friend.
(n) Previously, the appellant had expressed jealousy about the deceased's relationship with her estranged husband and A.
(o) At 7:52 am on 28 March, the appellant was discovered unexpectedly by a friend of the appellant's brother. He found the appellant asleep in a van outside his residence. The van was a work van owned by the appellant's brother. The van was often parked at the friend's residence, which was very close to the appellant's brother's workplace. However, the van had not been there on the previous night. The appellant did not drive, but relied upon public transport or lifts provided by friends. The deceased's residence was closer to the appellant's residence than to the friend's house.
(p) When he was discovered on the morning of 28 March, the appellant was wearing different clothes from those that he had been wearing on the night of 27 March. The clothes that the appellant had been wearing on 27 March were not found.
(q) The appellant and the deceased had communicated by telephone very frequently, but on 28 and 29 March the appellant made no attempt to contact the deceased.
(r) There was no forensic evidence linking another person to the murder. There was no suggestion that another person had a motive to murder the deceased.
