That's not the same thing as investigating a case. If there was a robbery at work, and you were urged to check your locker to see if anything had been stolen from it, would you consider yourself to be investigating a case? No. The characters in Texas Chainsaw Massacre seem to have no interest in looking at evidence, or trying to get to the bottom of who was behind the grave robbing. And it doesn't really lead them to the family. It was more a matter of wrong place, wrong time.
