Normal mayoral candidate Marc Tiritilli has officially filed papers requesting a discovery recount for the Normal mayoral election. Last week, incumbent Mayor Chris Koos was declared the winner by 11 votes. McLean County Clerk Kathy Michael confirmed Tuesday that Tiritilli is requesting a recount that will allow him to review ballots from seven of the 30 precincts. Michael says her office will receive more information about the review later. After the discovery recount, Tiritilli has until next month to file for a full recount with the courts.
