Woman and girls died at same block in 2004
The bodies of a 34-year-old woman and her two daughters were found at almost the same spot in March 2004.
The woman was dressed in a black cheongsam and black high-heeled shoes and had make-up on her face.
She had also dressed up her two little girls, aged two and one.
She took them up to the 25th storey of the block from where they fell.
It was not known why she chose that block. She did not live there.
She had tied a red string around the wrist of each girl and secured them to her own.
While no identification particulars were found, a note tied around her neck was said to contain a mobile phone number.
A coroner's inquest later ruled the deaths as murder-suicide.
