According to the Harry Potter Lexicon, the spell Homenum Revelio “reveals human presence in [a] target area”. It doesn't elaborate. Would Homenum Revelio be used only to find a living person, or could it locate a deceased individual, as well (For example, could it have been used to retrieve Mad-Eye Moody's body following Moody's death in Deathly Hallows?)? We already know Accio doesn't work on people – one cannot summon a person.
Q: Does Homenum Revelio only reveal the living?
Ideally, I'm looking for a canon answer from the following sources: The 10 Harry Potter books, Pottermore, or an interview with J.K. Rowling. Barring a canon answer, a subjective answer in the spirit of canon is totally welcome.
