When I read that "After Daniel's death, KE lived with Howard and Anna up until the day before Anna died. That increased the possibility.
In other words, KE and Howard were constant companions and that's what this scenario took...a real script.
Very hard to convict someone for killing a druggie with drugs.
I think Howard made a big mistake in taking the demeaning drugged up videos of Anna "For all the world to see" because it doesn't look like evidence of her drug use at this point. It looks like pre-meditated murder.
KE is covering her ass..Nothing to do with her would surprise me.
Maybe she was taking some of Anna's drugs she couldn't prescribe for her own self?
