Mystery still swirls over 2000 Aussie backpacker murder

Mystery still swirls over 2000 Aussie backpacker murder - a 25-year-old man was killed and his girlfriend repeatedly stabbed and raped while they were camping in Northern Thailand. In the ensuing weeks, men were rounded up and charged, later to be freed on acquittal. However, due to poor evidence and police skills, there is a chance the real killers will never be caught.
