JOHANNESBURG: South African police have found a bloodied cricket bat at the home of Oscar Pistorius following the killing of his model girlfriend, a local newspaper has reported.
But the Paralympian's father, Henke Pistorius, said he was certain his son acted ''on instinct'' when he shot and killed Reeva Steenkamp, 29, at his luxury Pretoria home.
Police sources have told the independent City Press newspaper that Ms Steenkamp's skull had been ''crushed''.
''There was lots of blood on the bat,'' one source told the paper.
Investigators have dismissed initial suggestions that Pistorius, 26, could have mistaken Ms Steenkamp for an intruder and City Press reported that she was wearing a nightie at the time of the killing.
''The suspicion is that the first shot, in the bedroom, hit her in the hip. She then ran and hid herself in the toilet … He fired three more shots,'' a source told the paper.
But Mr Pistorius snr, 59, said his family had ''zero doubt'' that Pistorius had shot Ms Steenkamp dead mistakenly thinking she was an intruder.
''When you are a sportsman, you act even more on instinct,'' he said. ''It's instinct - things happen and that's what you do.''
He said the Pistorius family was ''heart and soul'' behind his son and would do ''whatever needs to be done'' to help him clear his name.
His comments followed the family's release of a statement in which they described the athlete as ''numb with shock as well as grief'' over the events of the past three days. They said evidence gathered by the police ''strongly refutes'' any possibility of the premeditated murder charge with which prosecutors have said they will charge the athlete.
They also insisted that Pistorius, whose position as South Africa's golden boy was cemented when he won two gold medals and a silver at last year's London Paralympics, had no reason to harm Ms Steenkamp, his girlfriend of four months.
''All of us saw first-hand how close she had become to Oscar during that time and how happy they were. They had plans together and Oscar was happier in his private life than he had been for a long time,'' they said.
The family fightback came as reports emerged that Pistorius fought to save Ms Steenkamp's life after allegedly shooting her in the early hours of Valentine's Day morning.
Security guards and neighbours who went to his home on a security compound outside Pretoria saw Pistorius running down the stairs with the blonde model in his arms, a source quoted by the Afrikaans newspaper Beeld said.
Ms Steenkamp was still breathing, it said, and Pistorius tried to save her using mouth-to-mouth resuscitation. ''Blood splatters along the route that Pistorius carried her was further proof that her heart was still beating,'' the paper said.
