A body found in bushland near a motorway in Sydney's north has been formally identified as Qi Yu - the Chinese woman allegedly murdered by her housemate.
Ms Yu, 28, was last seen on June 8 at her Campsie unit which she shared with 19-year-old Shuo Dong and another woman.
Dong spent the evening of June 8 bickering with Ms Yu over cutting his lease short and bond money he owed her, court documents show.
Ms Yu's parents, who were speaking to her from China via WeChat, could hear the argument in the background about 7.30pm on the Friday night when the power to her Campsie unit was shut off. They didn't know it would be the last time they saw her alive.
Police allegedly found blood-like stains through her home and car, which was parked a few kilometres away.
Dong was charged with her murder less than a week after she disappeared.
Numerous searches of bushland were fruitless, even after phone signals narrowed the search area to bushland north of Sydney.
Almost seven weeks after she disappeared, on July 25, a wrapped body was found in bushland near an emergency stop on the M1 highway at Mount Kuring-gai.
It was formally identified as belonging to Ms Yu, NSW Police said on Tuesday.
