Honestly if poo ever hit the fan in my life I would probably delete my fb too. Like the second I started getting crazy messages from people. Sometimes LE even recommend doing that in order to slow rumors and prevent threats. I don’t think that’s too abnormal.
Just thinking out loud here, because it’s crossed my mind. What if they learned of their friends passing, had some drinks then decided to go for a drive to calm down and talk it over. Maybe they had more to drink then she admitted too and he went off the road. Having the windows down while cruising around (even in colder weather) isn’t too crazy. She bailed out of the car, he didn’t. She either was in shock, too drunk or did have a head injury which caused the delay and weird behavior after. Not saying that’s what happened but maybe? I can’t explain the no pants thing though. Hahaha maybe they were drunk and getting frisky? Maybe even while driving? Just random thoughts.
Also If the kids are still living at home they might have an idea of what the situation was before they went out for a drive. Was Jesse there even? Were they drunk? Upset? They may have some insight.
