Nope. Perhaps there is a connection in methods if not in actual suspects?
I find Greta's tortured language so distracting I end up paying more attention to her diction than what she is saying. That is one reason I refuse to watch her. It is simply too painful. Her guests always speak better than she does.
I have a hard time with Greta as well, not only her voice, but her face {bad botox job...yikes!}, I just hadn't switched over to Scarborough yet like I normally do, as I was cooking dinner. Wasn't there another similar crime recently? If I remember correctly, there was a man that was killed recently in this fashion too. The mainstream media is covering this by stating it was "upper body trauma" without releasing details, but I am sure I heard her say they were stabbed in the neck. Might just be coincidence, but it kinda creeped me out because of the other story.
