Details of the shocking sexual motive behind the Lin family massacre can now be revealed after the only surviving family member broke an eight-year silence.
Five members of Brenda Lin's family were brutally killed by her uncle Robert Xie in July, 2009, when he let himself into their North Epping home and bashed them to death with a hammer-like object as they slept.
Xie, 53, was this week sentenced to five life sentences and will never be released from jail.
Ms Lin, the eldest child of Min and Lily Lin, told the NSW Supreme Court trial Xie sexually assaulted her on a number of occasions when she moved in with his family after the murders. She also gave evidence of instances of inappropriate touching before the killings.
