Accused's grandfather testifies in Sydney murder trial
The grandfather of a teenager being tried for second-degree murder testified to hearing his grandson and girlfriend fighting in Sydney provincial court.
The 18-year-old is on trial for the stabbing death of his girlfriend in December 2010.
The 17-year-old girl had 104 stab wounds from several knives, according to a pathologist who testified earlier this week.
The identities of the accused and the victim are protected by the Youth Criminal Justice Act.
The accused's grandfather lived in the home at the time where the incident happened.
Much of his testimony was inconsistent with the evidence of previous witnesses, specifically relating to the times of events.
Crown attorney Dan MacRury said he's not worried about the inconsistencies.
"Every witness will testify differently and every witness sees things differently and certainly what we're looking at, is that at the end of the day we're looking at the totality of the evidence and we'll ask the court to make their finding on the basis of the totality of the evidence," MacRury said.
The grandfather told the court he heard the victim and the accused arguing, and that he heard the accused say 'I love you too.'
He also testified he heard a sound of banging on the wall.
The grandfather said he didn't go check what was happening because he has trouble walking, but yelled for couple to be quiet.
The court also heard extensive evidence from DNA expert Joy Kearsey.
The DNA profiles of both the accused and the victim were on knives collected at the scene, Kearsay testified.
One or both of their DNA profiles also matched samples collected in different areas of the house and on a pair of jeans and a sock, she said.
The trial, heard by judge-alone, is scheduled for another six days.
