All these guys would have needed to do is to find a car somewhere in a farmhouse where the owners are not currently home. Or, kill the owners before they can call 911. (if they broke in at night, quietly, and the owners were just a single couple or something, maybe they could have stabbed them to death)
They could then steal the keys from the kitchen, hop in the car, and start driving. Wear sunglasses and hoodies and hats and things so they can’t be identified from the road. After a few hours of driving (if they killed the owners and took the car at say 10pm, they could probably drive until 6am), they need to break in somewhere else and lie low. Steal a different vehicle from outside the search area.
There’s a huge luck factor. Every single person they see might be able to identify them from the photographs that were published. Every gas station they stop at, they might be identified by passerbys or the clerk. Every person who does identify them or they break into the home of, they need to kill. (Jordan Dorner choose to tie people up instead and was burned to death for his mercy)
But, I think it wouldn’t take an unreasonable amount of luck to get pretty far and hide for a while. This is a huge country, and if they can escape that dragnet - get far enough away that they are outside the radius being searched - and they don’t go out in public with their faces unobscured - they could evade capture for a while.
These stories almost always have the same ending. The only way they could evade capture long term is if they had the money to escape to an extradition free country and buy citizenship. They don’t.
If they had an accomplice the police don’t know about, and that person had enough money to support them (since they obviously cannot leave their hideout or work a job outside), they could possibly hide for years. But this is unlikely.
You can’t really blame them for their actions. Both men were going to be kept in a cage until death with little hope of relief. They might as well kill whoever they encounter, it won’t make their life sentences any longer. Maybe they could steal some nice food and try to enjoy it, huddling in some farmhouse with the lights off and the heat turned low to escape notice.
I know these are bad men who committed murders. But, what’s the point of locking them in a stinking cage and making them suffer until they are dead? Do you think that other potential murderers are going to think that far ahead and decide to skip a murder because they are afraid of such a fate? This seems unlikely, criminals usually don’t plan ahead very far. I think they should either keep the prisoners in humane conditions or kill them.
