CLEVELAND -- Suspected vote fraud is under investigation in several counties around the state, including Cuyahoga County, concerning voter registration cards for people who don't exist.

NewsChannel5's Debora Lee reported that three individuals are being investigated in Cuyahoga County. These people, known as paid volunteers, were being paid by voter registration organizations to go out and sign people up to vote.

The paid volunteers would receive $1 to $2 for every registration card that they turned in, but the people under investigation are suspected of filling out the cards themselves with names of people who don't exist, so they could submit them for payment.

Cuyahoga County Board of Elections director Michael Vu stressed that it is individual paid volunteers that are being investigated, not the groups that hired them.

"It's individuals that may be taking what is supposed to be a civic duty and taking advantage of what voter registration organizations are trying to do for the citizens of Cuyahoga County," said Vu.

Cuyahoga County election officials estimate that one to two registration cards out of every hundred are false.

The Cuyahoga County Prosecutor's office would not comment on the case.

Lee reported that Ohio is a key state for voter registration efforts because it is a swing state in the presidential election.
