A jury has heard that blood belonging to Stephen Bain was found on David Bain's shirt, shorts and socks in tests carried out two years after Mr Bain's first trial on murder charges.
A jury has heard that blood belonging to Stephen Bain was found on Mr Bain's shirt, shorts and socks in tests done two years after his first trial on murder charges.
The evidence was presented at Mr Bain's retrial at the High Court in Christchurch by forensic scientist Sally Ann Harbison, who completed DNA profiling tests of blood found on clothes Mr Bain and his father Robin Bain were wearing on 20 June 1994 when five members of the Bain family were shot.
Dr Harbison told the court that of the blood samples taken from Robin Bain's clothes, several full DNA profiles were found that belonged to him. One sample was not conclusive and she could only narrrow the DNA down to being that of Robin, David or Laniet Bain.
Dr Harbison told the jury she tested the blood samples in 1997 using tests unavailable at the time of the first trial.
She said she conclusively matched the blood on Mr Bain's shorts, T-shirt and socks with DNA profile of Stephen Bain.
The Crown says Mr Bain shot 14-year-old Stephen after a prolonged and bloodied struggle that left blood throughout the boy's bedroom and would have covered the killer.
Mr Bain denies the five murder charges against him, and says it was his father Robin Bain who murdered his family.
