Popescu and his cohorts allegedly had a fairly simple scam to steal from people looking for a set of wheels, but the trick worked very well. They posted fake vehicles on sites like Cars.com and Autotrader in 2012, according to The Washington Post. When someone was interested, the criminals would send a fraudulent invoice that appeared legit. Members of the ring opened bank accounts in the US with fake passports, and the victims would wire away the money without ever receiving the car.
According to The Washington Post, six of the members of this ring were arrested in 2012, and a warrant was issued for Popescu on December 20, 2012. US District Court indicted him on multiple counts, including wire fraud, money laundering, passport fraud, and trafficking in counterfeit service marks. He's now believed to be in Romania.
