When people go unexpectedly missing or are found murdered or both, everything in their lives is suddenly coated in an ominous patina. It's possible, if not probable, that Joey's illness was nothing more than that, a circumstance that happens to thousands if not millions, every day.
Oh, I have no doubt about that JMarsh. Stress? I recall allergies were a big issue for him as well. But back in 2010 and until the bodies were found, lots of theories were out there, one of them was that he was being poisoned. Surely I cannot be the only one that remembers this LOL
