NASHVILLE, Tenn. -- Nashville Mayor Karl Dean is calling for a full-scale security audit to figure out how to better protect residents’ personal information.

The measure comes after a break-in at the Metro Election Commission that put more than 330,000 registered voters’ personal information at risk.

Channel 4’s Jennifer Johnson learned on Wednesday that the office building the Election Commission moved into a year and a half ago may not be as safe as their old office.

Apparently, they used to have their own security system that was accessible only to the Election Commission offices. That's no longer the case, which may have made the break-in a lot easier to pull off.

On Wednesday morning, a member of General Services, which is responsible for security, did a walk-through of the current facility to evaluate security lapses and determine what steps need to be taken to prevent information from being compromised in the future.

Johnson also learned that two detectives have been assigned to the case and are canvassing area pawn shops and businesses known for fencing stolen property.

Questions like how much the breech will cost, where was security and who is liable if voters are defrauded are still unanswered.

There are two meetings set for Thursday; one at 2:30 p.m. and one at 5:30 p.m. to sort through these issues.

Metro will send out a letter to voters on Thursday that includes information about the break-in and credit report information.

Postage alone on the letters going out to voters will cost more than $122,000, which doesn't include the printing.
