Yeah no way he hides forever unless he goes to a foreign country.
Doesn't need to hide forever. Just needs to lay low until this story spins out of the daily media cycle.
On the premise that Laundrie wants to hide, he can shave, grow his hair out long and put on 40 pounds of weight. Ever see someone lose a dramatic amount of weight? How you almost can't recognize them, especially if you see them infrequently versus daily?
Law enforcement is looking for a single person. Laundrie is better off waiting and trying to find a single mother with a couple of kids. Come up with a cover story, meet a single mom with two kids coming over from the Border Crisis and try to start over somewhere.
How often have you walked into a restaurant or a gas station and seen a man, a woman and a couple of kids and not paid any notice to them? He's about 5'8, so he's average height and as long as he stays out of airports, public buildings and places that have high density of cameras, he's got better odds.
The pandemic also gives him some cover. He can wear a hood and baseball cap and mask all the time and no one will pay much attention. He could find a spot near a college campus when the pandemic lifts and source food everywhere. Think how much food is wasted or thrown out on the average college campus? He puts on a backpack and times his movements and he's a ghost surrounded by other early 20s people.
He needs six months of food and a place to hide and some access to clean potable water. He needs to keep his mind busy so if he has a laptop and some power source, he can just play games or read up on skills he needs to learn. As long as he's "air gapped" from anything from his previous life, he's got a chance.
If there was ever a time in American history to try to hide, this entire mess of a pandemic is some of the best/worst cover someone could have.
"I'm looking for cash work"
Why?
"Pandemic has hit me hard, things turned bad, restaurant I worked at shut down because of the lockdowns"
Oh? OK, I need a dishwasher. You can eat leftovers too. We were going to throw them out anyway.
Tragic. I hope he's caught, guilty or not, so the girl's family can have some closure.
Hiding anything in life is ultimately a test of discipline. If he's disciplined, he has a chance.
