Congrats on figuring out Prints and Pauper.
For Diggin' it- there is a lot of small evidence that is easy to miss. For the tracks, make sure you match them with the trailer treads. There is also some bird droppings that you can match with something near the spot where you found the tire tracks. [As well as a small piece of evidence about the dig site itself.] Make sure you have been thorough with the evidence found in the trailer, and then check the data cassette found in Adam's apartment which has the info about the trailer ownership. The psychic also has small bits of info in the case that pop up once and awhile, so make sure you check back with her.
hope that helps! if not, you can start a new thread for diggin it
