Thank you for that! FWIW, my career has been primarily in media and, the thing that strikes me so strongly with all these interviews (families, LE, friends, parents, etc) is it's so easy to imagine how it goes down. Producer/reporter finds contact for families/loved ones, gets a hold of them (persistence) then persuades them that they are on their side. "We want to get any information you want to the community because we want to help solve this for your sister/brother." I actually knew a victim of a high profile crime and, a producer and a friend, used the same technique on me. "I will ask you questions slowly, I am here for you." I am not here to bash the media but, when all is said and done, they are not on anyone's "side" but that of ratings which equals money and prestige for them.
And in this case they are seemingly getting nearly everyone(!) to talk. And, with a profile this high, finding a potential juror who hasn't heard anything about this case (and the bias that would come with it) will be extremely difficult. And, yes, I am do believe they will have a suspect unless he doesn't commit suicide first. Huge fear of mine.
So while all this information is good for sleuthing and for the media, it's terrible for those seeking justice.
