What does "heard" mean in "I allow fish and meat that is pure in three respects: One has not seen, heard, or suspected..."
This translation says,


  If a bhikkhu sees, hears or suspects that it has been killed for him, he may not eat it.


This commentary says,


  Furthermore, even cooked fish or meat of an allowable kind is unallowable if the 
  bhikkhu sees, hears, or suspects that the animal was killed specifically for the 
  purpose of feeding bhikkhus.


Both of these imply only the first of your two possibilities.
