Who is going to verify that conversation? (dead people don't talk and that conversation may have been just between Kris E and Anna.)
The whole thing is awful but I have feeling no charges will come about it all as it is all too hard to prove without reasonable doubt in a jury trial.
Yet, KE called BOTH the night before her death AND the morning she died and was told BY HOWARD (because no one else was around) that she was fine. (Wonder what time she called in the morning?)
