Federal investigators say they have identified the culprits in a violent robbery ring that has nabbed tens of thousands of dollars from Virginia businesses. Members have robbed four Virginia stores at gunpoint and were conspiring to rob a Pennsylvania bank and a D.C. drug dealer when they were arrested, according to a complaint filed in federal court in Alexandria.

Four men are charged in the operation. They are Edgar Perez-Suniga, Vahelo Escobar, Serfido Florian and Estanislao Perez.
