This is pure speculation on my part, but we had a 'bank robber' that lived in our neighborhood. He was a well respected retired businessman. He initially robbed banks a few hours away from here, and did not get caught. But then, perhaps out of laziness, he robbed a few local banks and was recognized by a customer in the bank.
So, it is possible, that a local perp was routinely driving out of state to hunt for prey. And for some reason he decided to commit a crime in his own neighborhood this time. Maybe he escalated so quickly that he could not control himself, if he came upon the perfect opportunity.
