University of Technology Sydney graduate Mengmei Michelle Leng was found murdered at Snapper Point, outside of Sydney. Police recovered Lengs naked body, which had been stabbed multiple times, from a blowhole at the popular tourist spot at 10.30am on 24 April. She had no jewellery, no personal items and no tattoos, and remained unidentified for three days.

It is understood police made contact with the womans family earlier in the week and had gathered items, including the womans toothbrush and hair samples, for a DNA comparison. New South Wales police released CCTV video on 29 April, showing the last known movements of the Chinese national. According to police, Mengmei had been shopping in Sydneys Pitt Street.

Wearing jeans, a long-sleeved blouse and carrying a red bag, the 25-year-old student told her friends she was headed to the Myer department store in George Street for an afternoon of shopping. Homicide detectives are now trawling through evidence, including CCTV footage around the national park and items retrieved from the water by police divers, to determine how she came to be dumped more than 100km from Sydneys central business district, where she was last in contact with friends.

We are getting a pretty good understanding of what occurred in that area during that time, said Detective Chief Inspector Gary Jubelin.
