Computer backup tapes that contain thousands of Social Security numbers of Tinley Park residents have been lost but officials say there's not much chance of identity theft.
Officials say the tapes containing information from as long ago as 15 years were lost while being transferred from the village hall to another site within the Chicago suburb on June 23.
It's a common procedure to move the tapes so they won't be destroyed if a disaster happens at the village hall.
Village Manager Scott Niehaus says about 19,000 residents and another 1,400 current, former or retired village employees will get letters about the incident.
Niehaus says there's no signs the information has been misused and it's unlikely it will be.
