Near as I can tell Luigi nullified all his carefully planned evasion and escape routing by deciding at the last minute he really needed a coffee from the Starbucks across the street from where he was about to shoot his victim and didn't keep his hoody up. If he'd worn a long-billed baseball cap, dark glasses, kept his hoody up and skipped Starbucks he'd probably never have been caught.
His evasion and escape plan was actually pretty good and he put a lot of effort into being hard to trace by arriving and departing NYC via bus and staying in a hostel, which makes it surprising he screwed up the easiest and most obvious things.
