No. Its not extra info.
He stated it in his interviews:
Chris Watts: I called her three times, texted about three times, just to say, you know, what’s going on, like, I did… I after… after I called her and texted her once, like, right maybe she was just busy, like, she’d just got back, you know, like, everybody probably calling her from her trip, she just got back from Arizona and… I figured that she is just busy but when her friend showed up that (inaudible) I registered, like, right, this isn’t right.
Chris Watts: Yes… uh… I’d text her a few times, called her but I didn’t get a response, that was a little odd and then her friend Nicole showed up about that afternoon, I see her on the doorbell camera and I was like: Hey, what’s going on? I can’t get ahold of Shannan and that’s when I was, just like, something’s not right. She’s not answering the door and she said the car was here, it’s like I gotta go home and got here, got inside and no… nobody was here, not… nothing.
Chris Watts: She was here at the front door and… that’s when I knew: Okay, like, if she’s not answering anybody else either, this’s… this isn’t like her. I mean, she works at direct sales business and that’s her, that’s what she does and for her not to respond to any of her people that, I mean, she hasn’t answered to me, that’s fine, I’m like she is busy, she has staff going on, but not to respond to her people, that was… that was not like her.
