I took it to mean his that he stopped using his phone (personal interaction). I Googled "digital footprint" (because I didn't know what it was, I'm not a cellphone user) and found the same definition said a variety of ways:
Simply put, a digital footprint is the record or trail left by the things you do online. Your social media activity, the info on your personal website, your browsing history, your online subscriptions, any photo galleries and videos you’ve uploaded — essentially, anything on the Internet with your name on it.
Just bringing part of the press release forward to show he no longer had Waze on. He had turned it off to use Snapchat (BBM):
- 11:24 p.m. – Enters the City of Luling on Highway 80, goes through the intersection of Hackberry Street (Highway 80 becomes Austin Street here)
Landry then stops using the Waze app and opens Snapchat. He continued on Austin Street to the intersection with U.S. Highway 183 or Magnolia Avenue, CCSO said. It’s believed he went through the intersection and continued on East Austin Street.
It’s at this intersection that Landry’s digital footprint stops.
Due to the above, I feel whatever happened, started at Blanche Square park. It's the intersection his footprint stops for one. For two, he can't pull out from a parking spot without the aid or Waze or he's lost (my way of saying what his dad jokingly says "he'd drive into a brick wall if Waze told him to"), IOW... he was highly dependent on Waze. Yet his car (note I don't say "he drives") ends up 5 miles down a dark gravel road that had multiple ways to turn around and head back to the lights of town had he simply not been able to retrieve his phone. Going further and further into the heart of Texas, into an oil field area and not many inhabited houses just does not make sense if HE was doing the driving.
I think his end destination was Blanche Square park which is why he turns off his lifeline, Waze, and turns on Snapchat, never to turn Waze back on. More notably, never to do anything online again. IMHO he Snapped with whomever he drove there to meet
as per the plan and then either something that had been planned happened, and we just don't know what that plan was (best case scenario as that means he's still alive), or something
unplanned happened. They then continued down the street that the car was pointing in (Spruce) and continued onto Salt Flat Rd and purposely spun the car out. It could have been their footprint that the dogs followed and it 'abruptly disappears' when they get into their accomplices car.
Why? No clue, but I don't have to know why something had to happen in order for it to have happened. Sometimes you just never end up knowing the why or the how.
So when LE is talking about more searches... I hope that includes a video search of cameras in the Blanche Square park area. Hopefully there is one pointing to the park. It would be a great place for a cam if they don't have one there. I'm not convinced he's down Salt Flat Rd.
