This is a dated article but I think it is interesting what Libby's GM says about the DNA evidencehttp://

We were able to speak with Libby’s grandmother, Becky Patty, who raised her and has done much of the public speaking regarding the case and started the brainstorming Facebook group. She mentioned she’s not sure where the Indiana police are on their investigation or when she would see justice for her daughter. Despite this, she remains hopeful. “Do I think they’re gonna catch him? Yes, I do. There’s too much evidence there for them not too. Are they catching them as soon as I would like? No, but we do have faith that they will get him one day. Sooner rather than later”.
Considering the evidence, it is unfortunate that police have been unable to make an arrest in the case. We asked Ms. Patty what she believes may be holding the police back. “Something that I am looking into more and more is I’m getting conflicting statements. I told my husband the other day I need somebody that can explain all this stuff legally to me. You have the golden state killer case, and they say that all came about through the analysis of DNA a different way. Indiana is one of the states that doesn’t search the DNA the way that they did. I’m getting conflicting data saying there is a way that they can do this and then I’m also being told there isn’t. I’ve got to do more research. If there is anything out there that could potentially help this case, it would be the police having better usage of searching DNA.”
