it's just incredibly sad. you think, oh my god. it is her. and you can believe that your baby is laying there, cold and lifeless. >> the next day, karen saw her baby again. saw more than her face. i noticed something that seemed to confirm what she already believed. it wasn't a hiking accident. she called the alaska state troopers. >> her knuckles were broken hard. so, i'm on the phone screaming to them saying, no you've got to get back you, have to take more pictures. these are defensive wounds. >> look again at bonnie's body she said. look harder. what happened to bonnie craig that september day screamed karen, was murder. >> coming up -- >> i think my mom felt very responsible. >> like, i caused this? >> yeah. they killed bonnie because of something i did.
