Johannesburg - Reeva Steenkamp's mother, June, says she was "unmoved" by Oscar Pistorius's apology to her and her family for killing Reeva.
"I look at Oscar the whole time to see how he is coping, how he is behaving. I’m obsessed with looking at him, it’s just instinctive, I can't explain it," Steenkamp told the UK-based Daily Mirror.
"I keep thinking, 'let me see how he's taking this'. He has been very dramatic, the vomiting and crying... I don't know whether he's acting."
The UK Press Association reported on Thursday on the Daily Mirror's interview with Steenkamp, who said it was "very traumatic" to listen to the graphic detail of the case.
She said she was prepared for his emotional apology when he took the stand on Monday.
"It left me unmoved. I knew it was coming. My lawyers had prepared me for it.
"I cried for the first time, ‘Yes’, but not because he apologised, because of the suffering and agony that my darling daughter went through and because I will never have her again."
Pistorius is facing a charge of premedited murder after firing four shots through a locked bathroom door, of which three hit and killed Steenkamp, on Valentine's Day last year.
He has said it was an accident and that he had feared for his and Reeva's lives after believing an intruder had entered his home in a security estate in Pretoria.

Meanwhile, Reeva's father, Barry, said he was making his own plans to attend the trial.
This is despite being advised not to fly after suffering a stroke.
He told the newspaper that he is making plans to get there from Port Elizabeth even though his wife June fears the stress of the trial could kill him.
