Simplest explanation is when the phone fell between the seat and the console, the phone's antennae was blocked.
"...today’s phones have antennas embedded inside the phone. If you’re not careful how you’re holding the phone, you can block the antenna, and lose your signal. Where exactly your embedded antenna is depends on you phone model..."
9 Reasons Why Cell Phone Signals Suddenly Go Bad
A digital footprint is any activity on the cell phone, including accessing apps, reading/composing emails, texting, ph calls, location tracking, etal.
I believe the digital footprint stopped around 11:24pm when he drove through the intersection of Magnolia Avenue and East Austin Street because his phone fell between the seat and the console, consequently, blocking the phone's antenna.
Ironically, there is a road sign at that intersection depicting a right hand turn is needed in order to reach I-10.
I believe Jason was a good student at TX State University where he was hoping to be accepted into their prestigious Sound Recording Technology program.
Further, I don't feel the accident had anything to do with smoking weed. Jason wasn't carrying much. Would it even be enough to last the two weeks during Christmas break?
This precious child had only driven home from TX State a few times and never at night. He heavily relied upon Waze for directions. By the time of the car wreck, he's already disoriented and probably scared. He also could have been searching for his phone. When his right rear slams into the tree, he may have suffered a brain injury or possibly a whiplash.
He exits the vehicle into the dark night with his backpack that he drops within 900' along with his baseball cap and pet beta. His watch, shoes and clothing are scattered along another short span. I believe the clothing and shoes were what he'd been wearing. So, he's nude at this point. We must assume he's freaked out.
I've been prone to severe panic attacks although they're not as common now as they were years ago. They begin with intense fear. The heart palpitates feeling as if the chest will explode. Breathing is fast and shallow. Trembling and dizziness occurs. Higher vigilance sets in. You
experience sweating as your body reacts with hot flashes. You feel like you're dying.
I believe Jason removed his clothing because he was suffering from a severe panic attack.
The search dogs last hit on his scent at the cattle crossing guards nearby. His aunt said it was at an abandoned home not far from the wreck site. I believe this location was as far as he got on the lonesome journey.
