Fraudster shows police how it's done, cops send tape to Shell

摘要

Some of the retailers hit by the scheme believed at first that they had suffered tank leaks - there were no other signs of theft. Some even ordered tank tightness tests, Oil Express sources say. One dealer whose monitoring system appeared to show a large inventory discrepancy started to figure out what was going on when he took a close look at his register tape. It showed fewer than 100 gallons sold that night but a bunch of "rejected card" transactions involving Visa gift cards. It was then he called police.
