At least 18 residents of Lancaster County recently had their identities stolen by thieves who used the information to make more than $11,000 of fraudulent purchases online.
Most of the victims work for BNSF railroad, but officials say they haven't found any evidence that hackers broke into their computers.
Lancaster County Sheriff Terry Wagner says the thieves set up PayPal accounts with the victim's identities and made purchases. The thieves spent several hundred dollars at a time and usually bought video games.
The thefts started last June, and most of the items purchased were shipped to a storage unit in California.
PayPal covered the purchases in several of the cases, so the victims didn't have to pay for video games they never bought.
