>> reporter: but no, bonnie was not at the airport to meet karen. her body was at the funeral home. >> i only got to see her face. it's just incredibly sad. and you think, my god, it is her. and you can't believe that your baby's lying there cold and lifeless. >> reporter: the next day karen saw her baby again, saw more than her face, and 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. so i'm on the phone screaming to them saying, no, you've got to get back. you've got to take more pictures. these are defensive wounds. >> reporter: look again at bonnie's body, she demanded, look harder. what happened to bonnie craig that september day, screamed karen, was murder.
