Audrey Melissa case. Raped and killed at the underpass connecting the Masjid Negara to Dayabumi Complex. She's from Methodist Girls' School and a lot of school girls from that school use the underpass.

Actually Nurin's case was not the worse unsolved murder. There was an unsolved murder case of another school girl back in the 80's where a metre-long piece of wood with three nails at the end forced into her vagina, puncturing her intestines, stomach and heart, and a piece of wire around her neck. That case was big in the late 80's and I believe the parents even dress her in red during funeral.
