I also small kid that time too but I remember because after that case my parents were extremely cautious for a few months. Cannot walk to school or go out play alone. It was huge in the 80's but died down because unsolved. I still remember seeing the Chinese newspaper where they reported her parents dress her in red during her funeral. There were rumors that it was done by a drug addict and the drug addict killed himself because being haunted by her. Not many people remember because it was pre-internet era.

There was also another case where an Indian Methodist Girls schoolgirl was raped and killed. It was also a huge case and I think it is also still unsolved today.
