Keivin Liwan Wai Yin was 19 when he had sex with the 15-year-old girl at his home in Hougang between June 1 and Oct 31, 2009.

The offence came to light when the victim reported to the police in February 2010 after she was found to be pregnant. She was admitted to hospital and had a miscarriage.

Sounds typical… but here comes the shocker:

A DNA profiling done showed that Liwan was not the biological father of the foetus.

Does that mean that the girl had multiple sexual partners? Then, why only this NSF got convicted?
