KEY POINTS:
Chris Kahui told a family member three times he wanted to hand himself in after his twin sons had died, saying he wanted to end everyone's hurt - but did not admit to harming his sons.
Stuart King, brother of the twins' mother Macsyna King and partner of Chris Kahui's sister Mona, gave evidence of how he held Cru's lifeless body to the High Court in Auckland today.
Mr King also admitted his sister Macsyna could have returned to the Mangere house the evening of Monday, June 12, when the Crown say the twins were fatally injured.
He is expected to be cross-examined on this admission when the trial of Chris Kahui for murdering three month old Chris and Cru resumes on Monday.
The twins died on June 18, 2006, within about 14 hours of each other at Auckland Starship Hospital after they were admitted to Middlemore Hospital on June 13.
Mr King said Ms King and Kahui had argued on the Monday morning, June 12, when Ms King had returned home because she wanted to go out again.
Kahui had wanted Ms King to stay at home and look after their three children, he said.
"There's no winning an argument with her."
Mr King said Kahui's father, Banjo, was at the house during the evening, after he bought Ms Kahui back from the hospital where she had been visiting her mother.
Everyone went outside at different times to have a cigarette together, he said.
Kahui was a "bit angry, down and pissed off that he couldn't go to the hospital" because he had to look after his children, he said.
Mr King, who shared the house with Kahui, said he returned to his room but was disturbed a few minutes later.
Kahui wiped tears from his eyes as Mr King described Ms Kahui running into their bedroom to tell him Cru had stopped breathing.
Mr King said he went into the twins' bedroom and saw Kahui cradling Cru.
Banjo Kahui was also in the room and was joined by Ms Kahui.
Everyone was "frightened and scared", he said.
Mr King said he took Cru off Kahui and sat down on the couch with him and tried to get him to breathe.
Cru's lips were dark purple and continued to go darker and his body was limp, he said.
Cru did not breathe for about five or 10 minutes but then started to breathe again but was not normal.
"When he was in my arms, when he was coming around, it was in short bursts, like sucking it in."
Cru's eyes were rolling back every time he tried to open them, he said.
Kahui wanted to get Ms King while Mr Kahui wanted to call an ambulance, he said.
Mr Kahui and Miss Kahui left the house to find Miss King, he said.
On the Tuesday morning Mr King heard Miss King arguing with Kahui.
Mr King said they decided to go to McDonald's and he drove with Miss King and the twins, while Kahui drove in another car.
Mr King said he did not notice anything unusual about the twins and did not discuss the twins with Ms King.
After returning to the house Mr King said he heard Ms King swearing outside, "going off her face" at Kahui.
Mr King said Kahui walked off while Ms King went into the house and collected items for the twins and left.
Mr King received two calls while he was at home from Ms King that afternoon wanting to speak with Kahui, who was with him on the Playstation.
Ms King was "upset, pissed-off, angry" but did not say why and Mr King passed the phone to Kahui, who left the room to speak.
Kahui seemed upset by the phone call but did not say why and resumed playing the game.
After the second phone call Kahui again continued playing the Playstation.
It was not until Mr King's brother-in-law came to the house they heard the twins were very ill and there was going to be an investigation.
Mr King said on three different occasions Kahui said he wanted to hand himself in to "end everybody's hurt".
Under cross-examination, Mr King said Kahui had never admitted to hurting the twins, even when he had asked him if he did it.
Kahui told him he was upset because he was the father and "should have been there to stop it".
