a bright and beautiful teen invites a friend to sleep over. the next morning, she s dead. oh, my god! i don t feel a pulse. what in the world happened? how could this be? turned out this was no ordinary slumber party. we know from their phones that this was a planned event. they had discussed it. they took pictures. stories surfacing of a dangerous experiment. the main purpose of having the sleepover was to try it. an experiment that just might tempt other teens. we know it s entered our high school. why the clues in this mystery could save a life in your family. you have a lot of people watching dateline that need to talk to their kids. welcome to dateline. parents always worry there are so many dangers out in the world a teenager can face. but at a slumber party in your own basement? how could something deadly have found its way there? taken a bright, talented girl. and could it happen in your town, to your child? here s kate snow with one small d
dangerous experiment. the main purpose of having the sleepover was to try it. an experiment that just might tempt other teens. we know it s entered our high school. why the clues in this mystery could save a life in your family. you have a lot of people watching dateline that need to talk to their kids. welcome to dateline. parents always worry there are so many dangers out in the world a teenager can face. but at a slumber party in your own basement? how could something deadly have found its way there? taken a bright, talented girl. and could it happen in your town, to your child? here s kate snow with one small dose. they re killing our kids and we need to do something about it. reporter: it s a new threat. she was saying, erin, your best friend died, and she kept yelling that over and over. reporter: and these teens found out about it the hard way. it s made out to seem like one of those, you re not really going to see it in your life kind of
feel real yet. but then it was like everything kind of hit at once and it was all just everything fell apart. reporter: investigators were surprised, too, but by something else. at the time, commander brian mueller was the head of the local drug task force. when he heard tara overdosed on lsd, it just didn t add up. we don t see that with lsd-related drugs. reporter: lsd, also known as acid, was created by a research chemist back in the 30s, and has been studied for decades. much is known about its effects. and in mueller s experience, he knows lsd can trigger deadly behavior. somebody jumps out a window or acts out because of the lsd? absolutely. yeah. injures themselves or gets in a fight or, yeah, jumps out a window. reporter: but the drug itself is not usually deadly.
he was on his way to do amazing things, and for me right now, it s about healing. i have wo friends still in the hospital that were shot. my best friends here. my whole colorado springs family was there so what i think i was doing is protecting my family, which is what i do. and sometimes to a fault, and i do things, because, you know, fight or fight, i tend to go fight a lot more. i don t know if it s good or not. it doesn t matter. either way, i went to the ground. as soon as i heard the rounds, i dove down, i pushed over my friend the best i could, and we both hit the ground, me and chip. i put my back against i tried to stand up and i fell. and then i fell against the it s like a bench seating, and at that point, i saw the shooter. i had no idea what was going on. but apparently i saw him going to the patio area, because i saw a lot of people in the window.
