"When I feel strong enough, I'll go there to ask him one thing: 'Why? Why did you kill my lovely Reeva?"

"I feel sure I will know the truth when I stand in front of him and demand an answer. I want to do that for my daughter."

The father of Reeva Steenkamp intends attending the murder case against Oscar Pistorius to look the paralympian in the eye, The Star reported on Monday.

"When I feel strong enough, I'll go there to ask him one thing: 'Why? Why did you kill my lovely Reeva?" Barry Steenkamp was quoted as saying.

"I feel sure I will know the truth when I stand in front of him and demand an answer. I want to do that for my daughter."

The Star published an interview by the UK-based Daily Mail, which also spoke to Reeva's sister, Simone, who said the family wanted to know the truth.

Barry Steenkamp had not been to court since the trial started early March.

His wife June has returned to the High Court in Pretoria each day for the trial.

Pistorius is accused of killing Steenkamp at his home on Valentines Day last year. He claims he mistook her for an intruder.
