(10 ILCS 5/19A-65)
Death of voter before opening of polls.
Whenever due proof
is made to the judges of election or election authority personnel counting early ballots that any voter who has marked an early ballot
as provided in this Article has died before the opening of the polls on the
date of the election, the ballot of the deceased voter shall be returned in the same manner provided for rejected ballots; but the
casting of the ballot of a deceased voter shall not invalidate the election.
