Ok, lets try this another way. Who can we defintirely rule OUT.
Mama Corleone
Kay
Anthony
Mary
Michael
Tom
Deanna
Pentangeli
Cicci
That leaves Rocco, Neri and Fredo as possible suspects, none of whom appear to be likely.
So who is left? Gotta be one of Ola's men who slipped in as a caterer, as PLAW has suggested.
