Hi all - looong time lurker and first time poster. Long story short, I've been following WS for a few years now (family connection to the Allison Feldman murder in AZ) and living in WI, only about 3.5 hours from Barron and having a cabin about 2.5 hours from there, it's somewhat "close to home".
First - the main thing I want to not for anyone searching out vehicle connections (and yes, I've sent this to the Sheriff's Dept. as well) is the pics they have of the Acura MDX are the 2007-2013 model (second gen). I owned an '08 in the past (black, ironically enough) and the years they have listed cover two different and very different-looking generations. The 1st gen 2001-2006 actually would look more similar to a Ford Edge. Not being that far from MSP, I could see an older MDX easily in this area, despite being more of a "foreign", city-dweller type vehicle (to stereotype a bit). Have they released any actual vehicle footage that would help narrow it down? The stock pics don't do much and don't really help get public input to verify the year/model...I've been astounded by the minute details some people can pick out even in a grainy video clip to really help.
I'll add to the chorus here that gunshots in the northwood and rural areas are common, day or night. Our cabin backs on to state land on two sides and there's a shooting range on the backside of our lake where people frequently do target practice for hours upon hours on the weekends (I got hit by some random birdshot last summer while fishing, thankfully on the way down at the end of its range...the local Sheriff had people rearrange the targets for obvious safety reasons). People will frequently "hunt" coyotes and/or wolves at night around there, so it's not out of the norm for loud bangs at just about any hour. Especially with the change in daylight times, dark is starting earlier and earlier, so while it's dark, it's not really that late.
Anyway, I have a hundred theories and a thousand thoughts running through my head about this and have been following the case from the beginning (Amber alert on my phone went off disrupting my GPS/Maps as we were using then to navigate Chicago through traffic/construction on our way back from vacation last week!), but I can pretty much disprove them all with what we think we know vs. what we know are facts (which is very little right now). Hoping for a good outcome, or at least as good as it can be, considering the known status of the parents.
