Murderer Robert Xie has maintained he is not guilty of brutally killing five family members following four trials spanning over more than seven years, declaring "I am innocent" to a jury moments after they found him guilty.
"I did not murder the Lin Family," he said in the NSW Supreme Court on Thursday as his supportive wife Kathy Lin cried following the majority verdict, reached after eight days of deliberations.
The jury found Xie used a hammer-like object to inflict horrific head injuries on his newsagent brother-in-law Min "Norman" Lin, 45; his wife Yun "Lily" Lin, 43; her sister Yun Bin "Irene" Lin, 39; and the Lins' two sons, Henry, 12, and Terry, 9.
It accepted the prosecution's case he was fuelled by resentment and humiliation at his perceived "inferior" status in the Lin family, when he crept into a North Epping home and bludgeoned five of his wife's relatives to death in July, 2009.
His fatal attacks came after he disconnected the electricity at their home and made his way upstairs in the dark, first killing his brother-in-law and his wife as they lay in their bed.
He then slipped into the next room and murdered Irene.
Next the former ear, nose and throat specialist went into his nephew's shared room, where blood splatter evidence revealed a furious struggle took place as the schoolboys were murdered.
Mr Lin's mother, Feng Quin Zhu, wailed as she left court.
Holding pictures her loved ones outside, she said "my son has been avenged".
"The law has given me truth," she told reporters in Mandarin.
The verdict came after two aborted trials and another resulting in a hung jury.
Earlier on Thursday the jury had informed Justice Elizabeth Fullerton they could not reach a unanimous verdict, however, she allowed them to reach an 11 to one decision, bringing an end to the six month trial.
Xie will next front court for sentencing submissions on February 10.
