KEY POINTS:
The Crown will close its case today against Chris Kahui, accused of murdering his twin baby sons in a stress-induced rage.
Crown prosecutor Simon Moore is expected to finish his closing address this morning to the jury of seven men and five women who will decide if Kahui is guilty of murdering Cru and Chris Kahui in June 2006.
Then Kahui's lawyer Lorraine Smith will summarise the defence arguments. The jury is expected to retire tomorrow.
Mr Moore began his closing address yesterday, telling jurors Kahui was a man who bottled things up before he "exploded" and bashed his baby sons.
The trial has heard from more than 60 witnesses over 5 1/2 weeks and the jury has been given 1390 pages of evidence.
Mr Moore said the evidence showed only Kahui could have killed the boys, and despite defence attempts to blacken the reputation of their mother, Macsyna King, nothing suggested she was anywhere near them when they received their fatal injuries.
The defence alleges Ms King inflicted the injuries after she secretly returned to the house when Kahui was visiting his mother in hospital.
"Some, most, maybe all of you will be sitting here wondering if Macsyna did it,"' Mr Moore told the jury.
They had been bombarded with evidence that painted a damning picture of Ms King, but that had not shifted the Crown position one bit.
When Ms King left her house the twins were normal, Mr Moore said. When she returned the next day they had been hurt so badly the best doctors in the world couldn't have saved them.
"Not one witness says she came back in the intervening time."
When she did return, and found the babies injured, Kahui told her "she should have been here", an answer Mr Moore said "conveys it completely".
"So if it wasn't Macsyna King, then who was it? ... The person who killed the twins is sitting over there," he said, pointing to Kahui who stayed emotionless, tapping his feet.
The Crown case was that Kahui, under pressure and frustrated, bottled things up until he took it out on his babies, attacking them in their nursery. When Cru was found not to be breathing, Kahui did not want to call an ambulance, instead asking his sister and father to search for Ms King.
Mr Moore said Kahui's behaviour after the twins were injured, his failure to call an ambulance and refusal to accompany Ms King to the hospital, pointed towards his guilt. He stayed at home, playing PlayStation, while "his babies are slipping away to death".
If the trial was a popularity contest Ms King would probably lose it because there was not a great deal to like about her, said Mr Moore.
"She's abandoned three children, used P, has an abrasive personality, and has previous convictions. It's natural to feel some disgust about some of these things."
He said it was true the case against Kahui was circumstantial, but when all the strands of evidence were combined they pointed to his guilt.
