GALVESTON, Texas (CBSDFW.COM/AP) — The top elected leader in Galveston County says two officials should resign for failing to protect the county from an electronic payment scam that totaled more than $525,000.

An outside review determined that no individual Galveston County employee was to blame for the loss of money.

But Galveston County Judge Mark Henry said Monday, auditor Randall Rice and purchasing agent Rufus Crowder should be held responsible.

The South Texas county discovered the theft in June involving a scammer who was pretending over email to represent a Houston construction company scheduled to repair roads.

County officials unknowingly made an electronic payment of more than $525,000 to the scammer’s account.

Both Rice and Crowder say they have no intention of resigning.

Crowder said the review conducted by a private firm, the Dawson Forensic Group, absolved a single office or person from being blamed for the scam. The report did note the county’s lack of safeguards to prevent the scam.

Investigators found that the county purchasing department didn’t have a validation system in place to ensure new bank accounts were valid.

The county’s treasurer, auditor, purchasing agent and information technology office have since implemented new security infrastructure to identify future problems as they occur.
