. >> you know, joe kondro and my first husband grew up together. joe was kind of a friend of the family. my daughter's uncle joe. >> kondro was facing the death penalty in cara's case, but prosecutors were willing to give him a deal if he admitted to the unsolved killing of rima it is traxler. kondro confessed and the deal with prosecutors spared his life but got him 55 years in prison. before any interview, my process is always the same. i study the case files and try to get to know what kind of killer i'm dealing with. from kondro's file, i know he is fairly typical of the rapist/murder. sick sexual fantasies lie beneath the surface. what's unusual is he liked to kill people he knew, an uncommon choice for a serial killer. i want kondro to help me understand this particular criminal type. kondro agreed to meet with me and i traveled to the washington state penitentiary in walla walla. i asked him to tell me about his final victim, cara rudd. >> i knew cara for a while. we played cards together and stuff. >> how would you describe her? as a kid. >
