Jingui Liu and Xiuyun Li.
A jury has been told that a grandmother, who is one of the four charged over the death of Shulai Wang, had told police in an interview she didn't know the woman, and that other "homeless ladies" lived in their house.
The bruised body of the 70-year-old from Hainan China was found in the water at Gulf Harbour two years ago.
The body was wrapped in plastic bags and bound to two SunRice bags that together contained over 15 kilograms of stones.
Xiuyun Li, 63, who's facing trial for kidnapping and manslaughter, alongside co-defendants - her son Kaixiao Liu, her daughter in law and her husband - told a detective she had not heard of the name Shulai Wang.
