The parents of Reeva Steenkamp say "justice was not served" after South African athlete Oscar Pistorius was acquitted of murdering their daughter.
June and Barry Steenkamp told NBC News of their "disbelief" that the court had believed Pistorius's version of events, the BBC reported.
June Steenkamp said: "This verdict is not justice for Reeva.
"I just want the truth. He shot through the door and I can't believe that they believe it was an accident."
She said she did not agree with the judge's decision.
"I really don't care what happens to Oscar, it's not going to change anything because my daughter's never coming back.
"He's still living and breathing, and she's gone forever, I just don't feel that this is the right sentence.
"They believe his story, and I don't believe that story."
Mr Steenkamp struggled for words after the verdict was delivered.
"It's easy for other people to look in, and see and listen, and have their thoughts, but only once they've gone through it will they know what we feel."
A friend of Ms Steenkamp, Hagen Engler also criticised the verdict.
"It is unfair, but it doesn't surprise me, in fact was pretty much what I expected from the outset, because he can afford the best possible defence and invest in private investigators to support his case."
Judge Thokozile Masipa found Pistorius guilty of the lesser charge of culpable homicide, saying the state had failed to prove he intended to kill.
He has been allowed bail ahead of sentencing on 13 October.
Judge Masipa said the athlete had acted "negligently" when he shot his girlfriend through a toilet door, but in the "belief that there was an intruder".
The Paralympic sprinter had strenuously denied murdering Ms Steenkamp after a row on Valentine's Day last year, saying he shot her by mistake.
South Africa's prosecuting authority said it would wait until Pistorius is sentenced before deciding whether to appeal against his conviction.
He will be sentenced in a month's time.
