This isn't a life you just up & leave. And not without someone noticing. Everybody knows everybody. Cattle = $$$. Land = $$$. It takes a lot to just walk away from those assets.
In the past I've ranch sat for a relative.
Morning:
Let out the chickens out of the coop (top off their water, put out their feed)
Feed the horses and donkey, let them out in the pasture
Bottle feed a calf or two
Feed cats and dogs
Spread out
cubes for cattle (they don't look appetizing but cows LOVE them)
Evening: repeat cycle and go out again to close up chicken coop at dusk, prepare feed buckets for horses and donkey for the next morning
And that was just for two horses, a donkey, two cats, two dogs, 10 chickens and 15 cows and however many calves. It wasn't unusual to make at least one call for the vet.
The Twombley's raised (quarter?) horses, cattle and blue heelers. That's a LOT of chores and mouths to feed on a daily basis. I feel so much for the Twombley daughter and the pain and chaos her parents have caused in her life. I'm assuming neighbors/friends have stepped in to make sure all critters are fed and cared for.
I guess we'll find out about Paul Grice at some point. Right now he could just be in the wind, laying low with relatives somewhere.
Possible he went to LE on his own and confessed because the murders were so horrible? Nah, probably not.
