Chinese student, Leng Mengmei takes a selfie with her aunt's Australian husband, Derek Barrett.
A former Australian IT worker, 27 year old Derek Barrett, has admitted killing his Chinese niece in April last year, reports thepaper.cn.
25-year-old Leng Mengmei went missing in April last year. Her uncle by marriage was arrested soon after in connection with her disappearance.
Her body was found floating in water in a national park 100km from Sydney. Autopsy results said Leng had been bound and gagged, and stabbed more than 40 times, with signs that she had resisted violently before dying.
On August 16, 2017, Barrett confessed to the crime and disclosed certain details.
According to The Daily Telegraph, court documents say Barrett had sexual fantasies about his stepdaughter. He even secretly shot a video when his stepdaughter was showering and crept into her room.
He faces 27 other charges including illegal detention, indecency, and the installation of secret camera.
