We begin though with a major development and the killing that has captivated and confounded millions of people around the world. It's captivated them because the shooting death of a glamorous model allegedly at the hands of perhaps the bravest Olympic athlete in modern memory could not be more stirring or tragic in and of itself. It's confounding because each day brings more news that does not seem to establish in any clear direction whether Oscar Pistorius, the "Blade Runner" shot Reeva Steenkamp dead a loud, wild, long argument or whether it was a horrific accident.

Tonight for the first time anywhere, the victim's brother Adam says that he and the rest of the family are no less confounded, no less torn, our conversation just ahead.

First, Pretoria, South Africa, and day two of a bail hearing that's playing out more like a complete trial. Robyn Curnow reports.

A police van took Oscar Pistorius back to his cell where he'll be spending his seventh night behind bars. The South African athlete's uncle says he is struggling emotionally.

"He is grieving and he is, I don't expect him to get over it even soon, and so he's still in an emotionally tough time."

In court, meanwhile, at Pistorius's bail hearing, more riveting details about what prosecutors say happened on Valentine's Day when Pistorius shot his girlfriend, Reeva Steenkamp, it was a version of the events counted vigorously by his defense team, prosecutors say witnesses had heard arguments coming from the Pistorius's home for an hour before the shooting. The defense argues the witnesses' house was 300 meters, about a thousand feet away. Pistorius's lawyers say he thought he was shooting at an intruder in the bathroom. Taking the stand and investigating officers said Pistorius used a cricket to break down the bathroom door, but the bat and the cellphone were found splattered with blood. Using a diagram projected on a large screen, the officers said Pistorius aimed his gun at the toilet, pointing out that he had to turn and fire at an angle in order to hit the toilet. More prosecution evidence, a floor plan of the apartment, which the state says shows Pistorius could not have crossed the bedroom towards the bathroom without realizing Steenkamp was not in bed. Defense attorneys pressed the police officer, who admitted that Steenkamp's body had no signs of an assault or signs of her defending herself. The officer also conceding he could find nothing inconsistent with Pistorius's version of the events. Prosecutors say police found bullets in a safe in the home, and they say that'll lead to charges of possessing illegal ammunition. But later the investigator said they did not establish whose ammunition it was. Prosecutors say there is no way that killing of Steenkamp was self-defense. They cited two previous incidence of police encounters with Pistorius that suggests he could be prone to violence. Adding that since they consider Pistorius a flight risk, he should be held without bail. But still, legal experts believe Pistorius has a good chance of spending Thursday night at home.

"Personally I would like to see him receiving bail at this stage, that the law can take its course, normal course, that we shouldn't have a trial by ambush."
