ARLINGTON, Wash. (2/23/09)--Police are investigating a series of thefts at a Washington state credit union's ATM where thieves tricked the machine's software program into doubling the funds they withdrew, while giving credit to only half the amount. The machine, at Boeing Employees CU (BECU) in Smokey Point, Wash., dispensed nearly $62,000 over several months (The Seattle Times Feb. 13). Police used surveillance cameras at the ATM and records of the withdrawals to break the case. One 17-year old girl, who was caught on camera taking $16,000 out of the ATM, confessed and led police to other suspects, including her 18-year-old boyfriend who withdrew about $10,000. The thieves tricked the software program so that the machine did not recognize it had dispensed money and instead repeated the withdrawals. A $100 withdrawal would net the thieves $200. They used a combination of personal accounts and prepaid debit cards to access the funds. The credit union said the machine has been fixed.
