Investigators are hunting for answers after the brutal murder of Chinese student Mengmei “Michelle” Leng.
Detectives have released CCTV footage and images of the 25-year-old, in an effort to retrace her final movements over the long weekend.
“I think if anyone knows anything about this – it’s like a piece to a jigsaw puzzle – if you’ve got any information as to her movements, come forward,” Detective Chief Inspector Gary Jubelin told reporters in Sydney on Friday.
