Welcome to the forum
@bbsmom2005 You are not alone. I struggled with this problem for half the day. I assume you mean that you clicked "Issue an APB" but you ended up at the Town Select screen?
When I posted at EA Answers HQ about not being able to travel to the crime scene two months ago, my report was merged into the "Map Reloading" thread below:

Like an idiot, I saved my game which caused the problem to spread to other save files. I had to re-install my game and use an earlier save.
Personally, I have just given up on the Detective career. Some players seem to have no problem with it, but the career is glitchy in almost all of my save files.
Good luck! (Sorry for ranting...)
