text: Double-amputee Olympian Oscar Pistorius got emotional in the dock on Monday as more graphic images of the night he killed his girlfriend were shown in court. 
   
   Earlier, his defense called pathologist Jan Botha to the stand. The athlete admits shooting Reeva Steenkamp, 29, but maintains it was a case of mistaken identity.

   Pistorius, 27, is accused of the premeditated killing of the model and law graduate. The sprinter insists he thought she was an intruder when he opened fire through a bathroom door on Feb. 14, 2013.

   With the hearing over for the day, it's time for a closing summary. This will be very similar to the lunchtime summary, as we only had about 45 minutes of evidence in the afternoon: 
   
   
   
   • Oscar Pistorius has taken to the witness stand to begin giving evidence in his murder trial. He began with a tearful, broken-voiced apology to the family and friends of Reeva Steenkamp, his girlfriend who he shot in February last year, believing – he says – she was an intruder. 
   
   • Pistorius said there is "not a moment" when he does not think about her family, and prays for them daily. He added: "I've tried to put my words on paper many times to write to you but no words would ever suffice" 
   
   • Pistorius said he had taken anti-depressants and sleeping pills since the shooting, often waking with "terrible nightmares" in which he dreamed he could smell blood. He said he often calls his sister to sit with him during the night. On one occasion he climbed into a cupboard to call her. 
   
   • He said his religious faith was the only thing to sustain him over the past year: "There have been times when I've just been struggling a lot. My God is a God of refuge." 
   
   • Pistorius spoke at length about his fear about, and experience of, crime. He said his his mother was worried about intruders and kept a pistol under her pillow 
   
   • Pistorius said a speedboat accident in 2009 which almost killed him left him fearful and withdrawn. 
   
   • Earlier, the first defence witness was a pathologist, Prof Jan Botha, who questioned prosecution evidence that Steenkamp must have eaten about two hours before her death at 3am, something which runs counter to Pistorius's statement that they went to bed at 10pm. 
   
   • Botha was questioned aggressively and at length by the prosecution counsel, Gerrie Nel, giving a taste of the likely cross-examination Pistorius will face. 
   
   
   
   • While this evidence was heard, including details of Steenkamp's injuries and photos of wounds and blood, Pistorius spent much of the time with his hands over his face, also retching.
target: – Oscar Pistorius' defense team is launching its case, and yet again, the testimony seems to have been too much for the athlete to take. Pistorius threw up multiple times—now a frequent occurrence—into a bucket as a forensic pathologist discussed the bullet wounds that killed Reeva Steenkamp, Reuters reports. The pathologist, Jannie Botha, agreed with the state pathologist regarding the sequence of shots that hit Steenkamp. A sobbing Pistorius and others in the court couldn't bear to look at graphic photos displayed, NBC News notes. Next, Pistorius himself took the witness stand and began by apologizing to Steenkamp's family. "There is not a moment and there hasn't been a moment since this tragedy happened that I haven't thought about your family," he said, struggling to speak clearly through emotion. Other noteworthy moments, via the Guardian: Pistorius said he has trouble sleeping. "I have terrible nightmares about what happened that night. I wake up and I can smell blood." He often calls his sister for help, once doing so from inside a cupboard, he said. He added that he never wanted to touch a gun again. He discussed his close relationship with his mother and her sudden death when he was a teenager. As for his physical abilities without his prosthetics, a question central to the shooting: "I don't have balance on my stumps. I can stand on my stumps. I can't stand still on my stumps."
