Mark Lundy has been accused of murdering his wife and daughter in the early hours of August 30, 2000 with a tomahawk-like weapon, which he has denied.
His lawyer David Hislop painted a scenario of the gruesome killings as he was cross examining ESR forensic scientist Bjorn Sutherland in the High Court at Wellington today.
Evidence was given to the court yesterday of blood spattered on the curtains in Mrs Lundy's bedroom that could be seen at each end, but a void in the middle.
Mr Hislop suggested the attacker must have been standing on the right side of the bed in front of the curtains.
Mr Sutherland agreed it was a possible scenario, but he said there was a question on where the attacker was standing because of the direction of the blood that was cast off the weapon.
"There might be a second position that may even be on the bed."
Mr Hislop suggested the attacker would be covered in blood.
"I would expect that the assailant would have spatter blood on the exposed clothing," Mr Sutherland said.
Mr Hislop said the attacker would have then targeted Amber, who was standing in the doorway of the bedroom, and in striking her would have some cast off blood fall on him.
But Mr Sutherland said he did not see evidence of blood cast off from the weapon near Amber's body.
Mr Hislop asked if blood would seep into crevices of jewellery worn by the attacker. Mr Sutherland said that would happen if the jewellery was exposed.
Yesterday Mr Sutherland said he tested Lundy's watch and two rings for blood, but none was found.
Also today, Mr Hislop confirmed Mr Sutherland had examined a dark blue jersey from the bedroom of Mrs Lundy's brother, Glenn Weggery.
He also confirmed with Mr Sutherland that blue and blue/black fibres were found under the fingernails of Mrs Lundy and Amber.
Mr Sutherland said he could not say how long those fibres had been there for.
