Timothy McVeigh, a native of Niagara County and a decorated soldier was eventually apprehended, convicted and executed for the crime.
McVeigh later admitted that he planned the attack for the second anniversary of the siege of the Branch Davidian complex in Waco Texas, which ended in the death of 26 people.
Tuesday, the names of all 168 victims' were read aloud, along with the observance of 168 seconds of silence in honor of each victim.
