State investigators say Fulton County voter records were altered after the 2012 presidential race, and someone used a red pen to add names to tally sheets in reverse alphabetical order.

The alterations happened after elections managers from two precincts signed off on the documents and submitted them to the main county elections office.

Georgia Secretary of State Brian Kemp is investigating more than 100 complaints from voters. Many of the county's voters had to cast provisional ballots because their names couldn't be found on voter rolls Nov. 6. The state claims that led to a shortage of provisional ballots and waits of up to five hours at some precincts before provisional ballots were delivered.
