INDIANAPOLIS (AP) — A data analysis firm hired by a voter registration group says its examination of Indiana's voter database has found thousands of people over the age of 110 who are likely deceased and still registered to vote.

The analysis was conducted for Patriot Majority, a group affiliated with the Democratic Party that state police are investigating.

Republican Secretary of State Connie Lawson last week flagged "thousands" of changes to voter information that she said could suggest fraud, but later acknowledged those changes could be legitimate.

Lawson's office says it took control of database maintenance in 2014 and is updating it in compliance with federal law.

Patriot Majority says analysis by the firm it hired shows that the statewide database is riddled with errors.
