Hey, I'm glad they caught this guy. But I'm thinking that there are a lot of high tech surveillance tools that law enforcement has at their disposal that the average citizen is unaware of.
Used to be a time in America where one could move to a different part of the country and start a new life under a new identity without drawing any attention. Criminals used to escape justice by doing this all the time. Even regular citizens who wanted to get away from family or a bad circle of "associates" could do that and get a fresh start. Not sure if that's possible anymore.
This guy doesn’t seem too bright. He probably used his cell phone while he was at the site of the murder. Then he probably didn’t switch cell phones. If he had thrown his phone off a bridge and then gone to a Walmart to get another one he might have slipped away. Except for the DNA
