police and prosecutors thought it was from the very first night. as the trial began, everyone was wondering how the state was going to prove the killing of reeva was premeditated. that oscar actually meant to kill her. >> i think the state has put a huge amount of work and a huge amount of money, and a huge amount of effort into making their case. >> a case that the prosecution argued was just as simple as it looked on day one. >> he can't deny that reeva was killed by himself, at his house. and that four shots were fired at her. >> attorney -- worked for south africa's national prosecuting authority. he previewed, cautiously, the prosecution's case against oscar. what everybody will be watching for is whether or not you can prove he intended to kill her. and you sound like a pretty confident the prosecution has enough to be able to prove that?

during that awful night he took reeva's life? we made a replica of oscar's bathroom door, a thick, solid wood. on a target range, we fired the same type of nine millimeter round from the same type of pistol oscar used. bullets ripped right through the door as if it was nothing more than gossamer. we also learned there something unique about this 9 mm. it's not only powerful, but exceptionally loud. so much so it's impossible to convey without blowing out your speakers. 160 decibels. louder than a jet engine at takeoff. makes your ears ring. according to prosecution spokesman -- many of oscar's neighbors heard those gunshots and something possibly more damning. screams. >> and it's not just, by the way, the screams. it's whether did people actually hear arguments prior to that. did you hear a woman shouting, something, irritated and annoyed, angry. and a man, screaming, shouting, and so on. >> the prosecution named more than a dozen neighbors as potential witnesses. five of them, according to the pre-trial report, said they heard arguing and shots, followed by the screams of a woman. and then further shots. >> and if people said, we heard gunshots, screams, gunshots, screams. you know. it's going to be pretty much hard for him to argue that the state didn't know that the woman screaming illicit the girlfriend. >> how would oscar ever be able to explain that way?

>> i do. i do my lady. >> how do you plead? >> not guilty my lady. >> it was all so dramatic. there were the neighbors. five of them, who testified off camera. they heard the gunshots when reeva was killed, but not just gunshots, they heard reeva terrified. >> her shouts, her screams were petrifying. i knew something terrible was happening in that house. >> the neighbor's husband even identical account. >> she started screaming again. at that point, the intensity and the fear in her voice escalated. >> and it was clear that this person's life was in danger. that's when the first shots were fired. >> oscar's next door neighbor testified she heard a loud argument more than an hour before the shooting. >> i heard sounds. it seemed like somebody was involved in a fight. and these people are talking in loud voices, my lady. and around about 3:00 in the morning, i heard four gunshots. >> which went through the door behind which reeva steenkamp was standing, said the prosecutor. he brought the door to court, bullet holes all along. and then the state's ballistic expert described how, shot by, shot through that door, oscar took reeva's life. >> most probably, it will gonna leave us -- when she was in a standing position between the door in the toilet seat. >> that shot shatters rivas hip. she fell back onto a magazine stand. but her hands up in a futile attempt to protect herself, as a tech and round pass through our upper right arm. the third shot, missed, but the fourth one struck her in the head. >> if we look at her defensive position, it's like if you see in this position, what a wound on her left hand, just between the two fingers with that and she was a bit facing down. a comes in here, it was penetrating the head of the deceased -- >> oscar response to his destiny, covered his head, plugging his ears and vomiting into a trash can. prosecutors made the case that oscar was a man governed by his emotions, not just grief and guilt, as seen in court. but also jealousy and rage. to make that case, the state admitted a string of text messages sent three weeks before the shooting. reeva to oscar. i was not flirting with anyone today -- i'm scared of you sometimes and how you snap at me. oscar responded, i was upset that you just left me after we got food and went to talk to a guy -- i was watching you touch his arm and ignore me. >> then, with six days to live, here was reeva again to oscar. >> i can't be attacked by outsiders for dating you, and be attacked by you, the one person i deserve protection from. but oscar's lawyer said the texts were nothing more than a lover's spat. so, what really happened that night? well, only one person survived, and he, oscar pistorius himself, took the stand off camera to tell the world his version. >> i heard a window open in the bathroom. i thought that there was a burglar that was gaining entry into my home. the first thing that ran through my mind was that i needed to arm myself. that i needed to protect reeva and i, and that i needed to get my gun. and then i heard a noise from inside the toilet. what i perceived to be somebody coming out of the toilet. before i knew it, i fired four shots at the door. my ears were ringing, i couldn't hear anything. so i shouted. i kept on shouting for reeva to phone the police. i unlocked the door, and i flung the door open -- and i threw it open. and i sat over reeva, and i cried. she wasn't breathing. >> south africa does not have a jury system, so oscar's testimony was for an audience of one, the judge would determine oscar's guilt or innocence. and five months later, when judgment day finally arrived, >> mr. pistorious please standup >> the judge made it clear she believed oscar. >> it was a genuine mistake as he thought he was shooting at an intruder behind the toilet door. the accused is found not guilty, and is discharged. >> not guilty of murder. the judge did find a oscar guilty of a lesser charge, culpable homicide. in the us terms, manslaughter. reeva steenkamp's parents devastated. >> i wanted the truth, and we didn't get the truth. that's the whole point, we did not get the truth. that's not what i believe or they believe happened. that's not justice, that's not justice. >> for them, the news only got worse. the sentence was much more lenient than expected. five years, and then just a year into the -- this happened. >> there is late news tonight from south africa. nbc news has learned one-time olympic hero oscar pistorius has been released from prison. >> oscar was allowed to move into his uncles compound to serve out the rest of his sentence. it was a strange ending to a strange story. except that wasn't the end of the story. in south africa, the rules are little different. prosecutors can appeal verdicts, which they did. and after the trial, after oscar was sent home, a higher court upgraded his conviction. >> the accused conviction from count one are set aside and replaced with the following guilty of murder. >> the court increased oscar sentenced to 2 to 13 years, and so he went back to prison. he will be eligible for parole in 2023. so until then -- >> on the evening of july 14th, 2019, as he sat in his car in front of the home where he had met him, two gunmen, unknown, fired into mark bachelor's car. >> police are investigating a case of murder. >> this murder was national news. south african broadcasting company was all over it. a targeted hit, the police called it. the rumors that bachelor got mixed up with a fast crowd, which got us to thinking about the time this sports god told us how, like oscar, he struggled to stay grounded, as his own fame and money soared. >> this is getting to fake and too much -- who's got more money?
