South African Olympic athlete Oscar Pistorius has told his murder trial he was “heartbroken” after seeing the body of his girlfriend Reeva Steenkamp.
Before his cross-examination ended, the court was shown a photograph of the toilet covered in blood where Ms Steenkamp was shot in February 2013.
The double-amputee runner denies murder, insisting that he mistook his girlfriend for an intruder.
He faces 25 years to life in prison if convicted of premeditated murder.
Mr Pistorius said that after shooting through the toilet door, he tried to break down the door with his shoulder, before using a cricket bat.
He said that all this time, he was screaming and in panic at the thought he might have killed Ms Steenkamp.
But the athlete said he stopped screaming when he finally opened the door and saw the body.
When asked why, he replied, his voice trembling with emotion: “I was heartbroken… overcome with sadness”.
On Monday, Prosecutor Gerrie Nel suggested the athlete was staging emotional outbursts to mask his difficulty in answering a barrage of probing questions.
Judge Thokozile Masipa temporarily halted proceedings on two occasions on Monday after Mr Pistorius broke down sobbing.
Shortly before the case adjourned for the day, Mr Nel said: “You’re getting emotional now because you’re getting frustrated because your version [of events] is improbable.”
The prosecutor, known as the “bull terrier” for his fierce style of questioning, then asked: “You’re not using your emotional state as an escape, are you?”
Both prosecution and defence have asked Judge Masipa to postpone the case until 5 May, following Tuesday’s cross-examination.
Mr Nel said members of his team were engaged in “more pressing” cases, which needed their attention, as well as “personal arrangements”.
The defence said the case should still finish on 16 May, as planned. The judge said she would deliver her judgement on this request on Wednesday.
The prosecution says Mr Pistorius deliberately shot dead his girlfriend following an argument.
On Monday, the athlete insisted he had not intended to kill anyone, saying: “I fired out of fear.”
Mr Nel said Mr Pistorius was changing his story from self-defence to saying he shot by accident.
The prosecutor said this was because the truth was: “You fired at Reeva.”
“It’s not true,” Mr Pistorius replied, bursting into tears and prompting the court to adjourn briefly.
Mr Pistorius said he and Ms Steenkamp had spent a quiet evening together before he woke up on hearing a noise in the bathroom.
Prosecution witnesses have testified to hearing a woman scream, but the defence disputes their testimony.
If Mr Pistorius is acquitted of murder, the court must consider an alternative charge of culpable homicide, for which he could receive about 15 years in prison.
He also faces charges of illegally firing a gun in public and of illegally possessing ammunition, both of which he denies.
There are no juries at trials in South Africa, and his fate will be decided by the judge, assisted by two assessors.
Mr Pistorius is known as the “Blade Runner” because of the carbon-fibre prosthetics he uses on the track.
Mr Pistorius said in his statement at the start of the trial that he woke in the early hours and walked on his stumps to the balcony, pulled in two fans, closed the sliding door and drew curtains. He said that shortly before he had spoken to Reeva, who was in bed beside him.
He said he rejected prosecution claims that a witness heard arguing coming from the house before the shooting.
2. Bathroom window
Mr Pistorius said he heard the bathroom window sliding open and believed that an intruder, or intruders, had entered the bathroom through a window which was not fitted with burglar bars.
“Unbeknown to me, Reeva must have gone to the toilet in the bathroom at the time I brought in the fans,” he said.
Mr Pistorius said he approached the bathroom armed with his firearm, to defend himself and his girlfriend, believing Ms Steenkamp was still in bed.
Both sides agree four bullets were fired. Ms Steenkamp was hit three times.
Mr Pistorius said he fired his weapon after hearing a noise in the toilet which he thought was the intruder coming out of the toilet to attack him and Ms Steenkamp.
He said he was in a fearful state, knowing he was on his stumps and unable to run away or properly defend himself.
Mr Pistorius said he rejected claims that he was on his prostheses when he shot at the door.
A witness told the trial she woke to hear a woman screaming and a man shouting for help. She said that after the screams she heard four shots.
Mr Pistorius said he went back to the bedroom after shooting at the toilet door, still shouting for Reeva. Lifting himself up onto the bed, he felt over to the right hand side of it and noticed Ms Steenkamp was not there.
Mr Pistorius said this was when he realised she could have been in the toilet.
5. Toilet door
Mr Pistorius said he went back to the bathroom but the toilet was locked, so he returned to the bedroom, pulled on his prosthetic legs, turned on the lights before bashing in the toilet door with a cricket bat.
Forensics expert Johannes Vermeulen told the court that the height of the marks on the door caused by the cricket bat suggest Mr Pistorius was on his stumps at the time.
6. Emergency calls
Mr Pistorius’s defence team say he then called security at the gated housing complex and a private paramedic service before carrying Ms Steenkamp downstairs.
A security guard claimed it was the other way round, and he had called Mr Pistorius first after reports of gunfire. However, phone records shown to the court revealed Mr Pistorius called the estate manager at 3:19am, a minute later he called the ambulance service and at 3:21am he called estate security.
A minute later he received an incoming call – estate security calling him back.
According to police phone expert Francois Moller, Mr Pistorius called his friend Justin Divaris a short time later and just after 4:00am he called his brother Carl.
