apprised of all developments. thanks, matt. we turn to a story sparking fierce outrage here at home. most kids love animals but this young girl says she also loves hunting them. she's 12 years old and she's already traveling to exotic safaris in pursuit of trophy kills. now after posing with her prey on social media, she's defending herself after igniting a fury of internet anger in the latest battle over big-game hunting. >> reporter: at just 12 years old, sharpshooter. a lethal big-game hunter both at home and abroad. the utah native came under fire after posting these images on her facebook page braids and bows. smiling next to the animals she killed while on safari with her dad in africa last week. >> it's something that i cherish and i enjoy and i want other people to see what i've been able to experience. >> reporter: in this post with the zebra, ariana writes, one of

but online, outrage. this post with a dead giraffe racking up over 73,500 comments so far. some calling ariana sick and an animal hater or threatening the 12-year-old's life. >> they love animals. but i mean, we love animals too, it's just we also love hunting. >> reporter: the father/daughter duo does have supporters online posting comments like, let the haters hate, hunt away, it's something my family has done for generations. and my dad got me into it when i was little. >> we're proud to be hunters. and we'll never apologize for being hunters. >> reporter: or for felling that giraffe. >> she had mentioned she'd seen a few of the other celebrity hunters that have shot a giraffe and she thought, that might be fun. >> reporter: aryanna's dad eli says their guides offered this particular giraffe to hunt. >> they actually had an older

that was creating problems for the other giraffes. he was harming the young giraffes. so he said, this one we could probably hunt if you were interested. >> reporter: but not everyone agrees with this justification. >> we hear that a lot, that in this modern day and age we have to proactively and excessively manage wildlife. i don't buy it. >> reporter: this isn't the first time social media has created a firestorm over big-game kills for sport. just this past week, this graphic video "new york post" showing hunter josh bomer hurling a spear and killing a bear. online, people calling his kill despicable. bomer doubled down in an interview with "the daily mirror," stating, you saul should be ashamed of yourselves for trying to kill a heritage that has existed for over a million years, literally since the dawn of man the spear has been a vital role in survival. perhaps the biggest uproar came

a beloved lion last year. cecil the lion was the star attraction of the national park. >> to me was one of the most magnificent lions i've seen. >> reporter: dr. palmer hired local guides paying over $50,000 for a hunting license. authorities at the time said palmer and his guides illegally lured cecil, first injuring him, then killing him, taking the head as their trophy. while the lawyer for the guide insisted nobody lion was cecil -- >> mr. palmer didn't know he was shooting this famed lion. >> reporter: the public wasn't convinced. 1 twitter user wrote, think it's safe to say that dentist walter palmer of lion-killing fame is the most hated man in the world right now. good stuff. palmer released a statement then saying, i had no idea the lion i took was a known local favorite, adding that he relied on the expertise of local professional guides to ensure my legal hunt,

activity i love and practice responsibly and legally resulted in the taking of this lion. he was never charged for the death of the lion and has no further comment. but big-game hunts are still enormously popular. even the trump brothers are fans of the sport. seen here with their so-called trophies. according to the humane society international, over the last decade american hunters have imported more than 1.2 animals as trophies. that's more than but for many, shooting to kill is not just sport. hunters like eva shockey believe that what you hunt you should eat. my abc colleague neal karlinsky first met shockey last year. >> they don't understand that we eat all that meat. what are they eating at their dinner table? do they have meat on their plate? do they go to whole foods and buy a $20 steak? do they know where that steak came from? >> reporter: shockey posing with

killed in north carolina, threats poured in on facebook. she says she had 5,000 death during the times in one day. >> you think when they attack me, that's just a form of fear basically. they are used to a hunter with a beard, chew in his lip, drinking beer. that's not what i represent. >> reporter: like aryanna, eva was exposed to hunting with her dad when she was very young. here she is at 7. >> how long have you been doing this? >> seriously five or six years now. >> reporter: she didn't start hunting herself until she was 20 and never killed an animal until this emotional moment captured on video. >> smoked him. >> did i miss him? >> no, you hit him. you hit him, that's exactly what will happen. >> i'm about to cry. >> don't cry. was it solid? >> i think so. >> you hit him solid. you could hear it. it went whoop!

i was excited, i was nervous, i was worried. >> was any of it feeling the impact of taking a life? >> as a hunt fer you don't feel remorse, if you don't feel reverence for that animal that just gave you a life, then i think you maybe should rethink it. because we don't think this animal -- that's an animal. that's a living animal. and it's now become food for people. >> reporter: eva and aryanna are part of a growing trend. the number of female hunters grew nearly five times as fast as male 2011. >> i want other women and youth to get into the hunting experiences because it's just -- it's funner than you could imagine and it's great. it's just awesome. >> reporter: aryanna says legal hunting is actually good for the wildlife and the local communities. they say the giraffe meat was donated to the local village and will feet 800 orphans over the next month. >> they don't understand the conservation aspect of it.

dollar industry. it creates millions of jobs across the world. boosts the economy hugely. >> reporter: but not necessarily. according to a recent report, only 3% of the $200 million in revenue from africa's big-game hunting trickles down to the local economy. >> study after study has shown minuscule amounts go back to the people on the ground in the communities that have to live beside wildlife. >> reporter: and animal advocates argue it does little for animal conserti kill endangered species to save them. >> reporter: despite the backlash aryanna says she will still keep hunting. >> i will never back down from hunting because i'm a hunter and no matter what people say to me i'm never going to stop. boxer claressa shields is purging her way to the podium. the flint, american began, native fighting in the olympics.

her first gold came in the 2012 games in london when she was just 17 years old. we caught up with claressa in colorado springs before she came down to rio. >> what's your favorite thing about boxing? >> my favorite thing about boxing is winning. >> reporter: there's a lot riding on those powerful shoulders, like helping take care of her family. >> i take care of my little brother. he wants to get him some glasses then he also takes his road test for his driving license. boy, you need a freaking haircut, my god. >> i need money for a haircut. >> $10. >> i don't got $10. >> it's a lot of pressure. basically you are going to be the main breadwinner for your family, right? >> i just accept it, you know. i adjust to it, i accept it. i want to help my family. >> reporter: oddly, a patch of canvas where people pummel each other was always her refuge. >> it's where i used to run when i didn't have a ride to

day. i remember being on trips and they'd go, so-and-so got killed, so-and-so got shot. >> i was never involved with the murders and stuff like that. i knew a lot of my friends that got killed. they were kind of into gang violence and around the wrong crowd of people. >> reporter: she wasn't spared from all the violence. in the documentary "t-rex" airing on pbs she said it came to her bedroom when she was a child. >> i've seen a couple of interviews in the the documentary in which you openly admit that you were child. >> it's weighing me down, feeling i'd been affected by that. i went to the university of michigan, there was a girl speaking about how her mom had sold her for drugs. for her to tell her story i was like, i would never. i felt like a coward. me hearing her what is made me decide that i would speak about it. i just keep anytime the back of my head. that's not my story, that's not why i box. i love boxing because i walk into the gym and i liked how

me being raped has nothing to do with that. >> it just amazed me how she's able to just key in and focus. >> reporter: jason crutchfield was her long-time trainer. she met him at berston fieldhouse boxing gym in flint. >> to be honest with you when she came, i didn't pay attention to her. i didn't want to mess with no female boxer. and took her on the wall and she was doing >> reporter: for eight years he would guide her through every punch she would throw. >> she would be the first one here every time. i say, be down there 8:00. she'd be there at 6:00 in the morning. >> reporter: going into the london games, shields split her time between training and high school, living in six different homes. >> i would move in everywhere, making my own decisions, trying to make the right decisions for my life. >> reporter: two months away from the olympic opening cher moans shields goes into the

and there she experienced her first and only loss of her career. but that wouldn't stop this champ from winning gold in london. flint boisterously welcoming her home. but gold didn't necessarily mean riches or recognition. the girl from flint got fewer endorsements than counterparts in other sports. the brawler in the ring seemed too rough. >> i'd like you to stop saying you love beating people up. >> you want me to stop saying that? >> stop saying that. >> why? >> tone her down a little bit. >> reporter: four years later she defeated that challenge. this time the endorsements are coming. >> if the boxing gym is no place for a girl -- then what does a girl's place look like? >> reporter: a rough childhood, now a source of strength. looking at the ring today, i bet none of them have had as hard a

did. >> i definitely think i'm tougher than most of them. at the end of the day we're all fighters, no matter where we come from, we're all fighters. >> reporter: a way out that's made her the first american woman to win two world championships and the favored for gold in rio. let's say you win the gold medal. >> i will. >> okay. what happens? how does your life change? >> if i win, my second olympic gold medal, i believe that i should get a freaking million-dollar deal to go two olympic gold medals at age 21? come on there's no way i shouldn't. >> reporter: who's going to argue? >> i'm going to look so mean when i'm in there. >> give me your mean boxing face. >> reporter: certainly. >> the eyes. let them slit. put your fists up. that's it. >> that's it? >> reporter: for "nightline," i'm matt gutman in rio. up next, why were protesters inside amy schumer's book
