Big Bear area lots of cabins?
Could he break into one and stay held up?
If the weather gets cold, he could survive.
There's a Winter Storm Warning from Fri, 3am until Fri, 10pm PST in Big Bear -- which will make it more difficult to find him if he's holed up somewhere. But at least he's not out shooting people.
My guess is if he's there, he'll need to get out before the storm hits, or hunker down. Unless he has an all wheel drive, he'll need chains or snow tires.
My ex-bil has a cabin there for vacation purposes, and there are many around his that are empty. I know there's no one at my ex-Bil's house right now.
Scary!
