Marc Garcia was a video guest on NG 5/11/16, too. "GRACE: I`m on it. I`m on it, Lisa Pineiro joining us from Midlothian. Justin Freiman, also on the story -- Justin, when you are trying to build a case, you look at direct evidence, such as fingerprints, blood evidence, eyewitnesses. You also look at behavioral or circumstantial evidence. Now, let me understand this, Justin. Missy goes to this gym practically every day for three straight years. But suddenly, she quits cold turkey two weeks before she is murdered. Do I have my facts straight?" http://transcripts.cnn.com/TRANSCRIPTS/1605/11/ng.01.html
From having perused NG at times over the years, I'm guessing the truthful answer to her query ("Do I have my facts straight?") would have been, "No Nancy, you've once again taken a snippet of fact and twisted it into something stupidly wrong and ultimately misleading." She's so prone to wild exaggerations to support her preconceived notions, and titillate viewers.
