The crush of cameras now gone, but the city of orlando, still reeling from the deadliest mass shooting in modern american history. 62 days later, its just as easy rifle in the state of florida. Youre focusing your attention on the high capacity assault rifle. Yes. The type of weapon that was used . Right. No one needs a highpowered weapon. No one. Reporter the gunman managed to wound victims with more than 200 bullets. Christine and so many others, learning the gruesome details of their loved ones murder in autopsy results released just last week. Why is it so important for you to have that information . Well, i need to though it haunts me that he was slaughtered and his entire torso was tore up with seven to nine bullets. So many shots, so quickly, so easily. And that he legally bought that high powered weapon just one week before the shooting. Reporter one last victim still clings to life in the hospital all these days later. But the damage left behind, not just physical. The emotional scars are fueling control. But despite a passionate Senate Filibuster and that dramatic sitin on the house floor led by congressman joe lewis, every single piece of legislation has since failed. We dont know who is going to be the next mass shooter. All we can do is try to protect ourselves from this type of weapon, so that when they do get their fuse lit, that maybe we can overcome them, relatively quickly. Reporter she echoed that sentiment in front of thousands at the Democratic National convention, supported by two of her sons friends. That love always trumps hate. Reporter her home state of florida, now a battleground, in every sense of the word. Shes been campaigning with progun control Senate Hopeful patrick murphy, working to unseat republican marco rubio.

Can you see the holes . Reporter those are the bullet holes . Yes. Thats unbelievable. Reporter for three hours, the trio was trapped in the nightclub bathroom. So the b came out of my back. Reporter and then a chilling moment. Coming face to face with the killer. I guess he must have thought i died with my eyes open. And i just kept staring at him.

Tiara experiencing the classic symptoms of stress. She said shes still hoping to find the right treatment. As for christines healing process what i have found that has. The most cathartic, believe it or not, has been being around christophers friends. I loved them all before anyway. I was always stealing his friends on facebook. Hed say, mom, stop stealing my friends. I said, i wont say anything creepy, i promise. Reporter on this night, christines hanging out with friends.

A ramp up to the olympics. Red corner, Michaela Mayer reporter michaela spends almost all of her time in the jim, three times a day, six days a training her body and her mind.

Reporter she said her life was starting to take a dark turn. When i found boxing, i switched gears. It focused me. I topped going out. I stopped partying. I cracked down in school.

Reporter to fund that goal, michaela has had to use her braun and her millions of girls are told theyre pretty. Reporter shes been the face of dr. Pepper. But not many end up becoming a model. Reporter shes even been featured for the muhammad ali collection. Have the prettiest foot work, the prettiest face.

How you fight in the ring, pretty face behind their products and its sad but true and thats the harsh realities of the world. Reporter in another harsh reality its the men, mayweather and pacquiao ring a bell . The top ranking female fighters make less than minimum wage. A typical championship fight for a woman professional, shed make about 5,000 still. But a man to make hundreds of thousands, and potentially millions of dollars. Reporter something that these heavy hitters are hoping they can knock out together. I do believe im going to get a chance to headline in vegas. You gotta be, you know, a woman that everybody wants to see fighting. Reporter but this year, they have their sights not set on green, but on gold. Just last month, we caught up springs, where she and the other olympic hopefuls from team usa, were living and training. Youre surrounded by athletes with the same common goal. So really, every direction you turn is an olympic focus. Its almost like youre back in college a little bit. Because its kind of dormstyle living and everybody eats in the same cafeteria, but its fun. Reporter in the leadup to the olympics, the fighters have become a family. Okay okay. Put your hand out. How cute is that . Its a sword oh, my gosh, i love it. Isnt that so cute . You better like it. Good job, mikaela, that is cute.

Double the cannon up, okay . Reporter mixing a little fun wither had fighting, the women even came up with code names for their punches. Get out your thats your jab. Fire the cannon. Walk the plank, youre walking them back towards the rope. Its a lot of work, so we got to find spots to kinda make ourselves laugh and have a good time. Reporter and now, after years of hard work, dedication, and singleminded focus, mikaelas made it to rio and she says shes ready for the biggest fight of her life. To get here. The chances of actually making it were very slim. But to have a dream, you have to believe in yourself. You have to believe youre the best before youre the best.
