This isn’t an isolated thing, but if someone doesn’t show up for thanksgiving or Christmas we automatically check the inmate records at the county jail. It’s happened a few times that someone’s absence is accounted for by an arrest and/or jail stay.
ETA: in 2016 my brother was a no show for Christmas and we checked the jails website. We saw our unique last name on their roster and assumed he’d been arrested. Turns out it was my uncle. I never did ask my brother where he was that year.
