how would you describe morgan as a little girl? >> she was very sensitive. if we were out on a walk and i would step on an ant hill on the sidewalk and she'd just look at me and she'd say, mom, don't you know how hard they work? don't step on those. she was beautiful. and amazing. and she made this world better. she was the best of me. >> three years ago on june 25th, 2015, at the age of just 15, chris' daughter morgan took her own life. >> i mean, as a parent, how did i miss it? how didn't i know? i have training in what to look for.
