It's been almost three years since the committal hearing of Kaihana Hussain, who the prosecution at the current trial, in Brisbane, says stabbed her mother and seriously injured her father - with a knife.

When the story first hit the headlines in November 2006, Hussain was 17 years old. Now, at the beginning of the three-week trial, she is aged 20. As far as I know, in the interim she has been living with a family in Adelaide.

Hussain's family moved from Adelaide to the Gold Coast, where the attacks occurred, in September 2006.

Hussain had been corresponding with a young Sydney man, Ben Brady.

The crown prosecutor, Michael Byrne, SC, says she wanted to kill her parents because they were thwarting her desire to be with Brady. Byrne also says the parents did not want to allow Hussain to convert from Islam to Christianity.

Hussain was born in Bangladesh but went to school in Adelaide.
