ATLANTA – (WAOK/AJC) – Investigators continue to round up almost a hundred suspects, wanted in a metro Atlanta auto theft ring. Local, state and federal investigators took part in ‘Operation Heavy Metal’ where authorities say the suspects would steal older model cars then sell them for scrap metal. They say the group preferred older model cars, because they were heavier, but mainly because, scrap metal yards do not check the titles for cars at least 12 years old. There is legislation in the general assembly that would address that so called loophole, and make it more difficult for people to sell parts for scrap metal. Investigators say more than 300 older cars have been stolen in the metro Atlanta area, in the past 2 years.
