Some observations after initial look at pics & vid...
1) We do have some answers now...how the flower stems got on the porch and that NG's blood was not there prior to these pics.
2) Currently I think this was his initial approach to the house - might change that opinion later - but previously I thought entry might have been elsewhere and he stood inside the doorway to remove this camera - now I don't think he was in the back yard first.
3) My doorbell camera (Ring) sounds an alert when motion is detected. I am now wondering whether NG may have been asleep and heard that alert that someone was at her front door and instead of checking the phone she just went to the front door and was assaulted there. (If so, it is possible that was actually caught on the camera before it was removed and they just aren't releasing it or discussing it.)
4) I agree this guy had a mustache but that doesn't necessarily mean he still has one today.
5) I've never seen anyone wear a holster quite like that. I know the guy on NBC has said it is an appendix carry but typically that is a holster that is tucked inside the pants - clips on to the belt or pants from the other side. This appears to be a hip holster being worn as an appendix carry on the outside. Not sure how to properly explain that but what I'm trying to say is that on a hip holster usually the clip is on the side toward the body and an appendix carry it is usually on the side away from the body. I've never seen anyone wear an appendix holster on the outside of their clothing like that - nor dangling down in front of the pelvic area like that - typically worn inside the clothing and up higher so it won't interfere with walking or sitting. Hopefully someone will recognize this holster especially if this guy is known to have worn it oddly like this.
6) Someone somewhere saw him with that backpack or jacket or ski mask - maybe when purchased - maybe in a hotel lobby or campground or gas station. I really hope the release of these pics leads to some tips that lead to some answers soon.
There's more running thru my mind but that's it for me for at least a few hours - I really do have to get some work done. I know this thread will move quickly this afternoon and no way will I be able to catch up and read everything but I'll pop in and out and read some of your insights as time allows. It was hard to see this man at her door knowing that she has now been missing for 10 days but I am glad to finally know they have something to go on.
