Investigating - finding out what happened to them. Maybe someone still knows, has seen the tragedy, there might be other clues, whatever. It's their last known location, the place to start. I am convinced that the storyline with Clem's parents will see some closure in episode 4. We WILL find out what happened to them, and that's the reason why Lee is taking her to the place.
