Exactly. I don't understand the hate against Maddy/JLH. It was a way to bring in the 9-1-1 aspect of the show, and JLH is a regular cast member. Looking through old 9-1-1 records was an interesting part of the show for me.
That part did work for me. Some people do live in the same places for years/decades. Even if they weren't in the same places, as a cop, Athena would have been able to find them - that's how she found the shooter. How else do you think real cops are able to solve cold cases now?
