Reporter today Oscar Pistorius walked into court a man facing life in prison. You feeling confident today . Reporter for shooting and killing model girlfriend reeva steenkamp. In a controversial ruling, the judge found the former olympian not guilty of the most serious charge, murder. Theres just not enough facts to support such a finding. Reporter as she laboriously read the decision, which at times outright supported the defense, pistorius began weeping in the front bench. And reeva steenkamps family hanging on every word. But their tragic ordeal not over yet. Pistorius will return to Court Tomorrow to hear the judges final verdict on the lesser charge of culpable homicide. In effect, manslaughter. And three additional weapons and ammunition charges. If convicted on all those counts, he could still end up sentenced to as much as decades behind bars or the blade runner could walk away not serving a single day in prison. Whether he sees a day inside a jail after hes been sentenced i think is actually quite unlikely. Reporter it was a trial that spanned seven months, punctuated by tears. Recriminations. You tilled a person, thats what you did, isnt it . I made a mistake. You killed reeva steenkamp, thats what you did. Reporter even a remorseful admission. Yes, i shot and killed reeva . I killed my lady. Reporter friends cant believe shes gone. It still feels surreal. It just feels like it didnt happen. It feels like it cant, couldnt have happened. Reporter since valentines day last year, spotlight ceaselessly on pistorius. He may have broken the worlds record for the most emotive defendant, filling the courtroom with his countless wails and whimpers. Why would this question make you emotional . Because this is the person i cared about, i dont know how people dont understand it. Reporter the trial had another center of attention notable for her absence. Im the next reeva. Reporter this u. S.

She was magnificent. She was gorgeous. She was talented. Reporter soon she graced magazines and on november 4th, 2012, captured the attention of south africas top bachelor, the blade runner. That night, their first date. He needed a date at the last minute, so throw your stuff together, come and be my date. Reporter oscar told a court that he was immediately smitten. I was very keen on reeva. I think i was more into her than she was at times with me. Reporter within weeks they had pet nicknames for each other. Boo. Angel. Rock star. Reporter by february 2013, their relationship appears picture perfect. Their stolen smooches captured on closed circuit camera at the supermarket. The day before valentines day, reeva tweeted, what do you have up your sleeve for your love tomorrow . For pistorius the answer was murder, according to the prosecution. The prosecutions version is, this is argument, he knows exactly who it is in the bathroom. She didnt go in to use the toilet, she went in because she was fleeing from him. Reporter legal expert matt murphy walked me through a scale model of the scene of the crime, pistorius bathroom, to demonstrate the prosecutions version of events. Reeva in a corner, defenseless. Tiny, line shooting a fish in a barrel with exploding bullets. Youre in here, and theres nowhere to go, theres nowhere to hide. She has no chance. Reporter four bullets later, reeva is dying. Pistorius puts on his prosthetics and returns to the bathroom and bashes down the door. The defense countering it was not a woman screaming that night but rather pistorius voice highpitched in hispanic after accidentally shooting reeva. A neighbor testified what she heard. What was the crying time . Waaaaah reporter in her ruling the judge discounted that testimony and almost all the socalled earwitnesses, saying the only witness who mattered was pistorius, who testified that his disability and his traumatic childhood had influenced his response that night. And that he was convinced an intruder had invaded his home. It was at that point that i was overcome with fear and i started screaming and shouting for the burglar or intruders to get out of my house. Reporter as the prosecution seized upon during the trial, pistorius did have an infatuation with guns. You are a gun enthusiast. You come from a family with lots of guns. Thats correct. 50 or more. Reporter prosecutor showing a video aired by sky news of pistorius on a gun range shooting a 9 millimeter pistol, the one that would ultimately kill steenkamp. And then theres pistorius lethally blasting away at watermelons. It exploded. Am i right . Thats correct. Reporter he was using the same hollow point exploding bullets that killed reeva. The distraught pistorius unravels. As i picked reeva up my fingers touched her head. I remember. I dont have to look at a picture, i was there. Reporter that side of pistorius, the raging, sometimes irrational, and highly emotional young man, something trish taylor, the mother of his exgirlfriend sam taylor, saw so much of. There was a lot of commotion in our relationship. Reporter in her book, excerpts of which abc news has exclusively obtained, reveal that she says he would scream at his 17yearold girlfriend sam taylor for failing to take her dishes to the sink. I think oscar was an accident waiting to happen. Reporter Melinda Ferguson coauthored the book. He was the bullet in the chamber, the nike ad. The guy always something was going to happen. In a sense it was all leading up to some tragedy. Reporter something pistorius may have foreshadowed in emails he purportedly wrote to trish taylor. Most of my adult life ive had moments i sabotage the good that i have. In a country where Domestic Violence is epidemic, Court Watchers worry about the judges messaging.

Most sensible people try to steer clear of really dangerous places. But not the adrenaline junkies youre about to meet. Theyre after one of the worlds biggest waves, on a lifethreatening quest to do something that seems impossible. Ride it and photograph it from the inside. Heres abcs chief meteorologist ginger zee. Reporter inside the barrel of one of the most dangerous waves in the world. Just raw, out in the middle of the ocean, kind of nastiness. Reporter elite surfers are about to attempt something that has never been done before. Getting inside that, an infamous swell, almost two miles off the coast of australia call ed the right. [ bleep ]. Reporter its a wave so powerful, even if you are lucky enough to get in it, the pressure of the break alone could kill you. Definitely lifethreatening, 100 . Right next to him reporter and these guys arent just going to surf it. They will surf in together, with a 20pound camera, attempting to capture what could be the most dangerous surf photo in history. The normal photographers shoot from a boat or they swim with a camera. This was totally out of the ordinary. Mark wanted to ride a wave behind me and he had this big camera and its pretty heavy, its like a wrecking ball. Reporter the entire journey unfolds in a new red bull documentary. But i met mark on a slightly less intimidating sea in rockaway beach, new york. I thought some of the words in the documentary were very cool, like, heavy. This is not heavy . This is not heavy, no. In big wave serving, this is not heavy. This is fun, though. Reporter fun is not what most would call the right. When you say big, how big is it, how tall . Wed be looking at, like, 25 feet tall, id say, to four, fivestory building. But the size isnt the thing. It the volume of this wave. Its like, as powerful as, like, an 80foot wave. The most dangerous things, just getting held down for such a long time that you basically run out of breath and pass out. Reporter to conquer this wave, the team has to strategize. On the back shooting video. Right, and kind of yeah. Reporter one wrong move could cost them everything. By mbiggest concern is that ill do something and it will take the camera away and ill go reporter they have little time to plan their approach. Rather ride a board like this thats been put through its paces. We just get on the jet ski and we start heading out into the middle of the ocean just on sunrise. Its still dark. Basically heading out into the middle of the ocean. Reporter this wave hits miles offshore. So, mark and taj have to be pulled out by jet key. Away are both planning to be pulled in by one jet ski rope, which is not really done, either. Its freezing cold. Im terrified. Reporter they manage to catch the wave on the first try. What is the feeling white when you get in . Everything is terrifying, but when you are inside the wave, you completely are surrounded by the ocean. Its like the roar of a plane and this weird air pressure going on in there. Its kind of surreal. [ bleep ], that was it. Reporter the first run is solid, but mark wants to go deeper. The word you keep using over and over, lets get deep. What does that mean . Its not in the washed out part. Its the positioning on the wave. We needed to be, what we say, deep inside the wave. That way well get the perspective of the amazing photo. Reporter they decide to go for a second run. Mark and taj ride the wave, just feet apart. I was trying to stay, like, kind of high and fast because i didnt want mark to hit me because obviously hes behind me. I didnt know how fast he was coming in behind me and the last thing we wanted was to get tangled together. Reporter mark has just 15 seconds to snap the photo before everything goes black. As im nearly coming towards the exit of the wave, i just end up, my board catches and im going too fast to handle the speed and i got cart wheeled and i got held down for, like, the longest ive ever been held down. Just doing big strokes to the surface. Reporter taj fights his way above water. I eventually popped up and i was seeing stars. Reporter but mark is missing. The jet sees are coming in and were looking for mark. Mark hadnt come up yet. And obviously he was in a more dangerous position than me, because he was further back on the reef. Reporter the team is frantic. Finally mark coming up for air, 45 seconds later. Almost blacked out. Reporter the longest time under in his life. Mark suffered a ruptured eardrum and a torn up face. Taj injures his shoulder. [ bleep ], i just went so deep. The camera was flying around. I couldnt swim anymore. I was just like, that it was just like dark and black in my eyes. Reporter it was the longest youve been under . Yeah, that was the longest ive been done. My ears are [ bleep ]. Youre crazy, man. Holding onto the camera, it stopped me from being able to use my arms to get to the surface, so, i had to rely on a life vest and it just took that little bit longer to get up. So, it was pretty scary. Reporter but to them, capturing the shot and surviving it was worth risking it all. Pushing the boundaries of photography and the angles you can get and just give people that perspective of what its actually like to be inside the wave like that. Definitely nothing like thats been attempted. The ride itself was probably only 10 to 15 seconds long. The memory lasts a lifetime. Reporter forginger zee in n next, shes a slave to the music.
