Right... Remember the dodgy Austrian who turned out to have paedophilia convictions (Wolfgang Zanic)? He hung himself and then Tui's dad shot the rope to get the body down, thereby causing more injuries from the fall which would mislead the forensic team.
Did he actually kill himself, or did Tui's dad plus the local chief of police murder him, then doctor the folk-dancing tape to show the kid running in woods etc. in order to frame him for kidnapping Tui?
That show took some thinking about!
