BB is posting biblical passages. This one about temptation, sin, and death is kinda weird but it could be about how frustrated he is in seeing comments about him on news articles and is tempted to post angry things.
I feel like such a creeper reading his FB. But I don't find the Randy Meisner post odd, as he appears to be into classic rock and maybe plays an instrument. So even though he's only around age 43, I can see him knowing Eagles' songs and who Randy is. (I'm guessing he is age 43 based on his graduation from high school in 1991.) Lana's death was bizarre.
He has been sick for a long long time. Ulcers in 2010 when he's about age 37? Then diverculitis? And so severe he had to go on antibiotics? Then a chronic "pain," then some treatment which briefly relieved the pain, then a minor surgical procedure. Maybe his digestive issue is a reason Missy was into healthy food. A loving, stay at home wife who does the meal preparation would do that for her husband.
Looks like he works for his Mom and step dad's business - gas station I think. He may be an employee or may have invested in it. Even if he owns part of it, it's hard to believe the family would get upset with Missy parting with her share if there was a divorce. Not that divorce was on the horizon, as there is no indication of that from his FB.
I don't see anything alarming.
What was alarming was creeping around video game discussions. Holy cow they are into role-playing, disguises and multi-use weaponry. Maybe this is just a nutter living in a fantasy world.
