In a major point of contention that has already emerged, prosecutor Gerrie Nel said Pistorius took the time to put on his prostheses, walked seven meters (yards) from the bed to the enclosed toilet inside his bathroom and only then opened fire. Three of the bullets hit Steenkamp of the four that were fired into the door, Nel said.
Pistorius said in his sworn statement that after o0pening fire, he realized that Steenkamp was not in his bed.
"It filled me with horror and fear," Pistorius said. The 26-year-old Olympian said he put on his prosthetic legs and tried to kick down the door before finally giving up and bashing it in with a cricket bat. Inside, he said he found Steenkamp, slumped over. He said he lifted her bloodied body into his arms and tried to carry her downstairs to seek medical help.
But by then, it was too late.
"She died in my arms," the athlete said.
The Valentine's Day shooting death hocked South Africans and many around the world who idolized Pistorius for overcoming adversity to become a sports champion, competing in the London Olympics last year in track besides being a Paralympian. Steenkamp was a model and law graduate who made her debut on a South African reality TV program that was broadcast on Saturday, two days after her death.
Nel charged Pistorius with premeditated murder and said the athlete opened fire after they engaged in a shouting match.
"She couldn't go anywhere. You can run nowhere," Nel said. "It must have been horrific."
A conviction of premeditated murder carries a mandatory sentence of life in jail.
Chief Magistrate Desmond Nair ruled that Pistorius must face the harshest bail requirements available in South African law. That means Pistorius' lawyers must offer "exceptional" reasons for the athlete to be free before trial, besides simply giving up his two South African passports and posting a cash bond.
Pistorius sobbed softly as his lawyer, Barry Roux, insisted the shooting was an accident and that there was no evidence to substantiate a murder charge.
"Was it to kill her, or was it to get her out?" he asked about the broken-down door. "We submit it is not even murder. There is no concession this is a murder."
Pistorius' emotional outbursts again played a part in how the hearing progessed, as it did during an initial hearing Friday. At one point, Nair stopped the hearing after Pistorius wept as Roux read a portion of the athlete's statement describing how Steenkamp bought him a Valentine's Day present, but wouldn't let him open it the night before.
"Maintain your composure," the magistrate said. "You need to apply your mind here."
Pistorius' voice quivered when he answered: "Yes, my lordship."
Affidavits from friends of Pistorius and Steenkamp read out by Roux in the hearing described the two as a charming, happy couple. The night before the killing, they said, Pistorius and Steenkamp had canceled separate plans in order to spend the night before Valentine's Day together at his home, in a gated neighborhood of Pretoria.
Outside the court, several dozen singing women protested against domestic violence and waved placards urging that Pistorius be refused bail. "Pistorius must rot in jail," one placard said.
As details emerged at the dramatic court hearing in the capital, Steenkamp's body was being cremated Tuesday at a memorial service in the south-coast port city of Port Elizabeth. The family said members had arrived from around the world. Six pallbearers carried her coffin, draped with a white cloth and covered in white flowers, into the church for the private service.
South Africa has some of the world's worst rates of violence against females and the highest rate in the world of women killed by an intimate partner, according to a study by the Medical Research Council. Another council study estimates a child or woman is raped every four minutes. While homicide rates have dropped, the number of women killed by current or former partners has increased, said the council's Professor Rachel Jewkes. At least three women are killed by a partner every day in the country of 50 million, she said.
Steenkamp campaigned actively against domestic violence and had tweeted on Twitter that she planned to join a "Black Friday" protest by wearing black in honor of a 17-year-old girl who was gang-raped and mutilated two weeks ago.
What "she stood for, and the abuse against women, unfortunately it's gone right around and I think the Lord knows that statement is more powerful now," her uncle Mike Steenkamp, the family's spokesman, said after her memorial.
He said the family had planned a big get-together at Christmas but that had not been possible. "But we are here today as a family and the only one who's missing is Reeva," he said, breaking down and weeping.
Pistorius has lost several valuable sponsorships estimated to be worth more than $1 million a year.
On Tuesday, the athlete was ousted from a pro-gay campaign being launched in Cape Town, organizers said. In a video axed from the campaign, Pistorius says: "You don't have to worry. You don't have to change. Take a deep breath and remember, 'It will get better.'"
And Clarins Group, which owns Thierry Mugler Perfumes, said in an email that "out of respect and compassion for the families involved in this tragedy, Thierry Mugler Perfumes have taken the decision to withdraw all of their advertising campaigns featuring Oscar Pistorius."

Paralympics refocuses on future without Pistorius
The head of the Paralympics is in a state of "disbelief" about the murder charge against Oscar Pistorius, but is trying to reassure his organization that is has a strong future without its star athlete.
Pistorius last year became the first double amputee sprinter to compete at the Olympics, and helped to generate unprecedented interest in the subsequent Paralympics in London.
As Pistorius was appearing in court Tuesday in South Africa, International Paralympic Committee President Philip Craven expressed his "shock and disbelief" at the runner's sudden downfall.
Craven told The Associated Press he is writing to IPC members urging them to "respect and observe" the legal processes while refocusing on "the way forward."
Craven insists "we've got so many stars coming through that this will not be an issue." Excerpts of prosecutor's case against Pistorius
Here are excerpts from the prosecution's affidavit against Oscar Pistorius, whom they have charged with premeditated murder over the Feb. 14 shooting death of his model girlfriend Reeva Steenkamp:
"The incident took place in the residence of the applicant (Pistorius) and we are confident that it will not be in dispute that (Pistorius) fired four shots, three of which hit the deceased and caused her death. She was unarmed and inside a toilet with the door closed. The applicant fired shots from outside the closed door of the toilet. ...
"There were two people in the house during the evening of 13-14 February 2013 the applicant and the deceased, who were in a relationship. The deceased arrived between 1700 and 1800 on the 13th of February 2013 and planned to spend the night with the accused. An overnight bag was found in the main bedroom and a cosmetic bag in the bathroom (scene of crime). The deceased was shot three times whilst she was in the toilet behind a closed door.
"The bathroom and the toilet is about six meters (yards) from the main bedroom and upstairs from the main entrance and living area of the applicant's house. A passage links the bathroom and bedroom. The house is situated in a security complex with 24-hour security available.
"The door to the toilet was broken open from the outside the only reasonable inference being that it was locked and could not be opened. (Pistorius) gained access to the toilet and carried the deceased downstairs where he walked into security guards. The main door of the house was not locked. (Pistorius) told his sister that he thought it was a burglar. We argue that this was part of the pre-planning to use as a defense. Why would a burglar lock himself into a toilet? There may have been an argument earlier between (Pistorius) and the deceased. ...
"There is no possible explanation to support his report that he thought that it was a burglar. Even (in) his own version, he readied himself, walked to the bathroom with the clear intention and plan to kill the 'burglar' and did so whilst the burglar was harmless and contained in a toilet. This in itself also constitutes premeditated murder of a 'defenseless burglar.'
"It is our respectful argument that 'pre-planning' or premeditation do not require months of planning if ... I ready myself and walk a distance with the intention to kill someone, it is premeditated."
