Why was he walking around at 12:30 in the morning if his dementia had taken a turn for the worse?
Maybe he couldn’t sleep and wanted to go for a walk. Yes, it is a bit odd and might attract the attention of the neighbors, but it is, or was, a free country.
I didn’t know that there was a curfew in Bakersfield. /sarc
Bakersfield is pretty much a Mexican war zone these days.
Who in their right mind would let a dementia patient take midnight strolls without supervision?
