Story highlights Olympian Oscar Pistorius is due in court Tuesday 
 
 Family: "The leaking of evidential material" does not advance the legal process 
 
 Pistorius is charged in the killing of his girlfriend 
 
 Photos released last week purportedly show the bloodied bathroom where she died 
 
 The family of Olympian Oscar Pistorius said Monday they are "shaken" by the "graphic images" leaked to the media last week that purportedly show the blood-spattered bathroom where the double amputee track star fatally shot his girlfriend in February. 
 
 "It has always been our plea that the legal process be allowed its run its course with integrity," the Pistorius family said in a statement. "The leaking of evidential material into the public domain, before the court case, does not advance this process." 
 
 The statement comes a day before Pistorius is due to appear in court where prosecutors are expected to ask magistrates to postpone the case pending further investigations. Pistorius, 26, is charged with killing girlfriend Reeva Steenkamp in the early hours of February 14. 
 
 The graphic photos of the crime scene were published by Sky News on Friday and show a trail of blood leading from a bathroom; blood on the walls, stairs and a couch inside the house, and a Valentine's Day card with "Ozzy" -- Steenkamp's nickname for Pistorius -- written on it. 
 
 The photo of the bathroom shows a toilet covered in blood, a door with a missing panel and what appear to be two police-marked bullet holes below the level of the door's handle. CNN has not been able to independently confirm the authenticity of the photos, and police spokesman Brigadiere Phuti Setati declined to comment on how Sky News obtained the pictures.

 Pistorius, known as the "Blade Runner" for competing on carbon fiber blades fitted to his amputated legs, has said he thought there was an intruder in the house. Afraid of being attacked, he ran on his stumps to the bathroom, where he shot through the door from a relatively low angle four times. It was only upon returning to his bedroom, Pistorius says, that he realized Steenkamp was not in bed and that she had been the one in the bathroom. 
 
 The state alleges it was premeditated murder: Pistorius had an argument with Steenkamp then put on his prosthetic legs, walked to the bathroom and shot through the door from a relatively higher angle, intentionally killing her. 
 
 His uncle told CNN last week that Pistorius is a broken man over the incident and described his nephew's grief as "unthinkable." 
 
 "What can you say if the person you love the most dies, and you were the instrument? How would you feel? It's unthinkable," Arnold Pistorius said. 
 
 His family said Monday they "fully stand behind Oscar." 
 
 "We believe in him, love him and will support him every step of the way in what lies ahead," the statement said. ||||| Sky News has obtained pictures inside the house of paralympian Oscar Pistorius - including images of the bloody bathroom where he shot his lover, Reeva Steenkamp. 
 
 The pictures have emerged as allegations that police officers involved in the investigation are being questioned following the disappearance of one of the runner's watches from his house. 
 
 This is the first time the public has seen the actual room where the athlete's model girlfriend was killed. 
 
 The images show a panel missing from the toilet door - and two police markers below the handle which indicate bullet holes - low down. 
 
 It is likely the defence will argue this backs up the runner's claims that he was on his stumps and shooting - from low down - at what he thought was an intruder. 
 
 The pictures inside the house show a trail of blood from the bathroom 
 
 The athlete has always insisted he and Ms Steenkamp had had a quiet night in together at his house, which is in a secure compound in Pretoria. 
 
 He says he got up in the early hours to bring in a fan from the balcony. But when he went back into the bedroom again, in the pitch dark, he says he heard a noise. 
 
 He has already told the Pretoria Magistrates' Court during his previous bail application hearing in February that he immediately believed there was an intruder in the house. 
 
 He says he grabbed a gun that he kept for security purposes in the bedroom and ran seven metres or so down the passageway leading to the bathroom, without his prosthetic legs on. 
 
 The tape shows two bullet holes in the bathroom door 
 
 There he fired four shots into the toilet door, which was closed. He insists it was only when he went back into the bedroom and realised his girlfriend was not in bed that it dawned on him it was her in the toilet. 
 
 The couple had only been dating a few months when the shooting on Valentine's Day happened. But the world's best known paralympian insists he was deeply in love with Ms Steenkamp and her death was a horrible accident. 
 
 When the athlete last appeared in court, he said when he realised his mistake he did everything to save his lover, battering the toilet door with a cricket bat to get to her. 
 
 The pictures inside the house show a trail of blood from the bathroom as the paralympian carried Ms Steenkamp downstairs after shouting for help, with flecks of blood on the wall, on the sofa downstairs and on the landing.

 There is also an image of the gift that the model had wrapped up ready to give the athlete. Stuck on the top of it, is a card with just one word - Ozzy - her nickname for him. There is a container of heart-shaped sweets too. 
 
 But the prosecution believes a very different version to the one presented by Oscar Pistorius. 
 
 It maintains the athlete's girlfriend ran into the toilet after a row with the sportsman - and he deliberately targeted and shot her - having taken time to put on his prosthetic limbs beforehand. 
 
 This act, the prosecution maintained at the bail hearing, was tantamount to pre-meditation. 
 
 Reeva Steenkamp was shot dead on Valentine's Day 
 
 Other photographs show footprints in blood. The investigating policeman, Warrant Officer Hilton Botha, has already admitted he walked through the scene without wearing protective foot covers, potentially contaminating the evidence. 
 
 Warrant Officer Botha was taken off the case after that emerged - as well as the news that he himself was facing seven counts of attempted murder. He has since retired from the police service. 
 
 Now, there are further allegations about the police conduct at the house. Two different sources have told Sky News that other officers are being investigated too after the disappearance of one of the athlete's watches from his house 
 
 The South African Police Service, when contacted by us, refused to comment. 
 
 But the latest allegations will only add to the impression that the initial investigation into the killing of Reeva Steenkamp was not entirely above reproach. ||||| Oscar Pistorius is "battling" with his grief for killing girlfriend Reeva Steenkamp, his uncle said Sunday, while the athlete's family criticized the broadcasting of graphic images that purport to show the bloodied site of the fatal shooting on Valentine's Day.

 The family made the criticism in a statement in response to Sky News on Friday showing images said to be the blood-stained bathroom and two days before the double-amputee runner is due in court for a hearing leading to his murder trial. 
 
 "We were shaken by the graphic images, leaked into the public domain this week, of the accident scene at Oscar's house," the family said, appearing to confirm they are from Pistorius' home. 
 
 "It has always been our plea that the legal process be allowed (to) run its course with integrity. The leaking of evidential material into the public domain before the court case does not advance this process." 
 
 Pistorius' uncle, Arnold Pistorius, later said that his nephew would be ready for trial, adding he had "no doubt in my mind that he's not a murderer." 
 
 "He's battling. But with the family behind him, his sister living in the same house as he lives, Aimee, they assist him a lot," Arnold Pistorius said in excerpts from an interview given to South African television show Carte Blanche on Sunday and released by the family. "And we are preparing him. He will definitely be ready. Being the mind that he is, being the man that he is, he will know what it's going to take to do this event. 
 
 "So I think what we're saying is he will be ready once the court case starts and he will be able to stand as a man in that courtroom." 
 
 This will be Pistorius' first court appearance since he was freed on bail Feb. 22. The family contends evidence will prove his contention that the shooting was an accident. 
 
 The 26-year-old runner is charged with premeditated murder for the Feb. 14 death of Steenkamp. He denies the charge, saying he shot the 29-year-old model and law graduate by mistake thinking she was a nighttime intruder in his home. 
 
 The images have not been verified by The Associated Press or South African police. Sky News said it "obtained" the collection of photographs of Pistorius' home, but did not say where from. 
 
 Oscar Pistorius has been living _ sometimes in isolation, according to his family _ at his uncle's house since being bailed. Since then, there have only been two reported public sightings of him: a grainy cellphone photograph of the runner wearing carbon fiber blades at his practice track, plus a visit to a Johannesburg restaurant. 
 
 He cut a broken figure at his bail hearing, sobbing through much of the proceedings. The multiple Paralympic champion has also given up competition for the rest of the year to focus on his trial. He faces a life sentence with a minimum of 25 years in prison if convicted. 
 
 "Aspirations? You know, if you'd asked that question to Oscar, he would say: `Uncle Arnold, I know I've got a purpose in life. God told me I've got a purpose in life.'" Arnold Pistorius said. "Whether that is running, whether that is whatever, I don't know. I don't want to speculate on that because that is for him to decide, but he says he's got a bigger purpose in life." 
 
 The images of Oscar Pistorius' home appear to show the inside of the toilet cubicle where Steenkamp was hit by three of the four bullets fired through a wooden door. They also show a bloody trail leading out of the toilet and into the main bathroom and a footprint in blood, as well as two marks on the door that Sky says indicates bullet holes. 
 
 Despite questions being raised over the professionalism of the South African police, Pistorius' family said it trusts the legal process and believes the evidence will acquit him. 
 
 "As a family we fully stand behind Oscar as he prepares to appear in court this Tuesday," the family said. "We believe in him, love him and will support him every step of the way in what lies ahead. We continue to have great faith in the South African legal justice system and believe that Oscar's account of what happened on that terrible night in February will be borne out by the evidence that the defense team will lead in court."

– Days ahead of Oscar Pistorius' first court date since February, his family says they are "shaken" by leaked pictures of the bathroom where girlfriend Reeva Steenkamp was shot dead. The photos obtained by Sky News (which are here and graphic) appear to show the blood-stained cubicle where Steenkamp was shot three times and a bloody trail leading out of the cubicle into the main bathroom, the AP reports. "It has always been our plea that the legal process be allowed to run its course with integrity," the Pistorius family said in a statement. "The leaking of evidential material into the public domain ... does not advance this process." Family members say they are fully behind the double-amputee runner, who says he shot Steenkamp after mistaking her for an intruder. At the hearing this week, South African prosecutors are expected to ask for a postponement of the case pending further investigations, CNN reports.
