then another pause. then three more, that's when we grabbed our friends and we just ran. >> i first heard the shots, and then i heard people start running. everyone was panicked. we turned off the lights and locked the doors. >> reporter: a students ran in. >> one of the students who had one into my class believed she had been shot. got the gunshot wound which we thankfully have. >> jimmy: yes, classrooms are equipped with kits to treat gunshot wounds. >> i've never had to treat a gunshot wound as a choir teacher. there's something wrong. i held a bleeding child in the room with 40 sobbing children. i'll never be the same. >> i illed yelled at my teacher. >> reporter: his parents had been preparing him for this day since he was 4 years old he said. >> i did have my water bottle just in case. it's like dy>> reporter: k-9 un

posted on his account, and i can also confirm that it has been changed since this incident. >> if somebody has altered that, it's really important for law enforcement to figure out who altered it and why. i guess i'll be surprised if they don't find a fair amount of information online. >> reporter: and tonight yet another community in america is setting about burying its dead, and again, they are children. >> we always think these are drills, that they don't really happen here. and unfortunately, it did. and everybody's just in shock. we're all in shock. we're horrified. it's a great community, and for something like this, it's too close to home. >> reporter: for "nightline," matt gutman in santa clarita, california. >> our thanks to matt. coming up next, a lifetime of resilience. tina turner's story taking to the stage, her triumph's simply the best. woman 1 oc: this is my body of proof.

40's in leather than a lot of us looked when we were 21. >> reporter: but most importantly, that voice. electrifying the world as part of her "break every rule" tour with hits like proud mary. >> i think for the moment anyone heard the song "the best," they thought, yep. that's the kind of song tina turner should be singing. ♪ simply the best better than all the rest better than anyone ♪ >> reporter: now, the life of this legend blossoms on broadway in a self- titled musical, "tina." >> hello there, stranger! >> hello! >> it's a new life form for tina without me! >> reporter: what starts as a broadway show transforms into a full on rock concert. a spiritual experience through a

story that deserves to be told: about an extraordinary woman who overcame racial injustice and abuse at the hands of husband ike turner. >> she is at the forefront of the hashtag me too movement even though her me too was a long time ago. >> reporter: 32-year-old powerhouse adrienne warren plays the title role. >> i think people are now becoming more and more empowered to take control of their narratives and i think tina is one of the, you know, prime examples of that. and she is perseverance personified. >> i didn't want his money. all i wanted was my name! ♪ i'm your private dancer do what you want me to do ♪ >> when you actually get to know the details, the nuances, and about what she went through, you just cannot believe that someone has gone through. that many things and has come out on the other side with light and love. >> why do you want this to

happen? >> okay, now, this is going to be a little difficult. i don't! i don't need a musical! i don't need another show! but i get cards and letters with what people think about me and the legacy i led. people say i gave them hope. >> reporter: her story was adapted for the stage by award-winning playwright katori hall. >> we've known the stories, the headlines. it's not that we don't know it, but we don't know it like this. >> no, you don't know it like this. to be in the room with violence, to be in the room with triumph, i think that's the thing that really moves audience member every night. >> she will turn 80 this year and her indomitability continues to evoke awe and respect. >> reporter: as she sings about on this german tv show, her

story starts in a "little old town in tennessee" nutbush. the year is 1939 and "tina" is actually "anna mae bullock." >> my father was a sharecropper and actually when i grew up, i worked in the fields picking cotton and i always dreamed of being an actress while in the fields. i hated that. i didn't like it at all! >> she finally escaped nutbush when she moved to st. louis in the mid '50s. st. louis is where she met ike turner. >> and what she yearned to do was to get a chance to sing with that man because she knew she had a great voice. >> when he saw tina and she opened her mouth and sang he must have realized right away that he had something he had never had before. >> by the early 1960's she sings on a song called "fool in love." when that record was sold to a record label, ike turner turned to ana bullock and said, "i'm

going to keep all the money and you are going to be known as tina turner." >> he had this amazing instrument and he would just use her as an instrument. >> reporter: realizing what tina could do for his career, ike marries her. >> the bigger they got ike must have thought, "i got this good thing here. i can never let her go." >> i did as i was told. and it's almost as if you can put yourself in the position of always being told and it just doesn't feel good all the time to be under someone's hand. >> is that what it was like? he was in total control? >> absolute. >> reporter: daniel j. watts plays ike turner in the broadway show. growing up in the confederate south, he saw his father get beat nearly to death by a white mob and succumb to those injuries later. so he developed this pattern of "this is the world." when he was able to enact power, he did full-fledged, and unfortunately tina caught the brunt of it. >> when he was bitter, he was just real awful and real difficult to get along with. and by being a sort of

physically violent man, you never knew when you were going to get it. my life with ike was maybe one that many are familiar with their husbands are -- they -- practice brutality. >> he sent her to the emergency room multiple times for black eyes for bloody noses for lips that were swollen for wounds that would cause her to bleed from every part of her body. >> reporter: years later, audiences would painfully watch the extent of ike's abuse play out on screen in the film "what's love got to do with it?" starring angela bassett and lawrence fisburne. >> why did you stay so long? >> i felt responsible, i felt that i couldn't leave because too many things would be destroyed. and i stayed because i cared. and when the time actually arrived i had no longer cared because i was living death anyway so. >> reporter: "living death"

became a feeling so painful, so despairing, that it led tina to try to take her own life one night in the late 1960's. she wrote in her memoir, "i simply couldn't take any more and swallowed 50 sleeping pills." a decade later, tina finally found the courage to leave ike. >> tina turner probably brought more attention to domestic abuse than anyone had up to that point. >> she played an amazing role in making sure the world understood that this should not be tolerated in any way going forward. >> reporter: when their divorce was finalized in 1978, she was penniless. >> he owned her, i mean actually. >> he owned all the publishing rights and she couldn't the songs. >> no promoters would book me because they say, well, "it's not ike and tina. she doesn't have a record. there's nothing i can promote." >> she had to step out but she did scream for that name.

>> yes, she did. >> so she kept the name. it might be turner, but it's tina. tina turner, that's me. that's mine. >> reporter: her perseverance gave way to a hugely successful, international rock and roll solo career that brought along with it a transformative new look and sound. tina was now able to do music the way she wanted to do it. >> and then the next thing you know, we had "what's love got to do with it?" >> if you heard that story today, a black woman in her 40's, trying to make it in the music industry, in rock and roll, you're like, "i don't really know about that." today -- >> let alone -- >> let alone -- >> 30 years ago. >> when she did it. >> it's just persistence. if you believe in yourself and you're good at what you do and you know that you already have no doubts the thought alone and believing it will make it happen for you. >> reporter: i cannot overstate how much permission she gave women. black women definitely, but

women period. >> she's sold two hundred million albums over her career. she has eight grammys. >> she was inducted into the rock and roll hall of fame. there aren't that many women in the rock and roll hall of fame, let alone black women. and thus, a new generation of listeners found themselves with their "hero." >> we don't need another hero. >> reporter: that hit was 34 years ago. today, tina is retired and living with her husband, erwin bach, in switzerland. she has survived a number of medical setbacks including a kidney transplant, but she came to new york city to celebrate the show's opening night. >> this musical is my life but it's like poison that turned into medicine.
