The longer version (18 minutes long) of the documentary "The Lad We Knew" about Andrew's case was released a few days ago on Youtube. (Easy to find by title). His father, Kevin, speaks in the documentary, including about what it's like to live with that ambiguous loss and how in retrospect, they really did not see any warning signs prior to Andrew going missing. ETA: There is also good information about the "Missing People" charity.
