(Richmond, IN)--Armed robbers struck a Richmond business overnight. At just after midnight Wednesday morning, two men armed with what appeared to be handguns with silencers entered the Shell station on U.S. 40 near the state line. Investigators checked surveillance video and nearby businesses but have not located the suspects. One is described as a white man in a Carhart jacket. The other appeared to be a bi-racial male. There were no injuries. That Shell station has been the target of several robberies in recent years.
