An expert in the Lundy trial today told the High Court in Wellington it's likely a tomahawk was used.
Mark Lundy is being retried at the High Court in Wellington for the murder of his wife Christine and daughter Amber in their Palmerston North home in August 2000. Lundy denies the charges.
Describing the attack as bloodied and ferocious, Mr Sutherland told the court a tomahawk was the likely weapon that was first used when Amber Lundy tried to flee from her mother's bedroom.
Mr Sutherland also gave evidence about forensic results he obtained during the homicide investigation, including taking blood samples and DNA from the bodies of the victims.
Under cross-examination from David Hislop QC, Mr Sutherland told the court that he collected a controlled sample of fibres from a dark blue jersey found in the bedroom of Glenn Weggery, Christine Lundy's brother on 31 October 2000.
Mr Hislop asked Mr Sutherland whether he had found dark blue fibres under Christine Lundy's fingernails. Mr Sutherland said he found visible purple, blue and black fibres.
The said traces of blood as well as two visible blue and grey fibres were found beneath Ambers fingernails.
The jury also heard testing conducted at Glenn Weggerys house detected blood on a pillow, a handkerchief and light blood staining on a pair of underpants. Further blood was detected on a hand basin.
Mr Weggery gave evidence earlier in the trial about how he had discovered the bodies of his sister and niece in their home on August 30.
Under cross-examination by the defence, Mr Weggery vigorously denied being involved in their killings.
