Thieves have targeted the ATMs of at least 13 7-Eleven convenience stores and a liquor store in the D.C. area since Sunday. Six of those stores were targeted early Wednesday. The thieves are described as organized and sophisticated. They work fast and are believed to be using a stolen police radio to avoid getting caught, according to law enforcement sources. Police said the thieves use firefighters’ tools such as heavy-duty pry bars and a portable hydraulic spreader, known as the Jaws of Life – which is usually used to free people from the wreckage of car crashes. The DC Fire Academy was recently burglarized of similar equipment. The thieves intimidate employees and try to disable security systems, but not always successfully. A clerk at the 7-Eleven on South Dakota Avenue in Northeast D.C. said three people came into the store at 2:30 a.m. Wednesday and shouted orders.“[He] said ‘Don’t move!’ He gives orders, said, ‘Don’t move. Just sit!’” the clerk said. The men used a power tool to break into the ATM and ran off with cash. They tried to destroy some of the store's computer and surveillance equipment and then took off, the clerk said.
