UPDATED 4.19PM: The High Court has heard police suggested Christine Lundy’s brother was responsible for her death, and her daughter’s.

Mark Lundy’s on trial in Wellington for the murder of the two in Palmerston North in 2000.

Christine Lundy’s brother Glenn Weggery is the first Crown witness to take the stand.

In cross examination defence lawyer David Hislop asked Mr Weggery if he visited the Lundy's home the night Christine and Amber were killed.

"As I've already told you several times, I did not," he replied.

David Hislop said Christine Lundy suffered what pathologists call ‘defence injuries’.

"Did she try to fend you off?" Hislop asked

"No she did not as I never went in the bedroom and I'm not going to sit here and be accused of it," Weggery replied.

Hislop says police wondered why Mr Weggery called 111 when he first saw Amber lying on the hallway floor, instead of rushing to her aid.

"And their suggestion was that you knew she was dead because you'd killed her."

"They incorrectly suggested that," Weggery said. 

Weggery told the court after seeing Amber, and calling emergency services, he went to see if she had a pulse.

"And when you got to Amber what did you see?"

"Her head was cracked open at the back. Blood was everywhere."

Weggery says he then saw Christine Lundy lying dead in her bed.

Christine Lundy's friend Karen Keenan took the stand this afternoon.

She was the second person to arrive at the Lundy's home the morning the pair was found dead.

"All the back of her head was very matted and bloody," she told the court.

"There was a huge pool of blood in the crook of her arm. There was blood all round the walls and the roof."

Keenan also told the court that the Lundy family was paying hundreds of dollars a day in interest on a business venture, a few months before the Lundys were killed.

She says Christine told her she and Mark were paying $600 a day interest on a winery venture.

"I remember saying to her 'How the hell do you sleep at night with that hanging over your head?' and she said that Mark was sorting it out, that he was getting investors."

The Crown claims one of Lundy’s motive for killing his wife, was to ease his financial pressure through her life insurance payout.
