This is not correct. Motive does not have to be proven.
Intent is generally inferred from circumstantial evidence. For instance if a blood stained knife is found at the defendant's house, and DNA tests reveal the blood to be that of the victim, and the victim has mysteriously disappeared, a jury can easily infer that the defendant has intentionally stabbed the victim to death.
Nothing more is required.

I totally agree it is not correct, but only is that not correct, the Prosecutor will not even bring up the subject of motive. There is no motive. She didn't know him, he didn't know her . They were strangers to each other. There is no known link between them, nothing to create or nurture a motive, any sort of motive.
Any motive, that is, that has legal mitigating effects. The motive he had to kill her was what any murderer has, up until she died, she was a witness to his attack on her. Attack being what VICPOL said they have evidence of.
The DPP does not have to bring a motive of the killer to court. It is up to the defence to find some rational explanation (motive) for their client. They do this in the hope of convincing the judge to factor in something that might reduce the eventual sentence. Motive has nought to do with police. Or the DPP. A clear motive assists in detection, but no known motive does not hamper detection of a crime.
That is what the police Commander said. She was 'attacked' and it was not a hit and run accident.
Murder without motive, that is, motive that anyone other than the accused understands, makes up a lot of murders, particularly those of women, by men. Even killers rarely understand their own motive, except it seemed a good idea at the time. Not so much when in court.
No one else , at all, has even hinted at a third person, or fourth person. and so on. Not the police, not the DPP, not an newspaper, or TV channel, and most importantly not at any stage his legal representative, which, if there was such a creature, that's the first , second and third thing his defence would be shouting from the steps of the court.
