Rufina HernandezOne of two suspects sought in the Nov. 7 killing of shopkeeper Rufina Hernandez has been arrested, D.C. police announced last night. Andres Lopez, 45, of no fixed address was taken into custody without incident on Thursday afternoon near 4th and Kennedy Streets NW, only about five blocks from La Casa de Morata liquor store. Hernandez was shot and killed that Saturday night during the course of a robbery. Two suspects are believed to have entered the store and demanded money, a request with which Hernandez complied, but one of the suspects shot her anyway. D.C. Police Chief Cathy Lanier declined to indicate whether Lopez is believed to be the shooter, but reiterated that the search for the second suspect continues. “We look forward to getting help from the community,” Lanier said. “There is still work to do.”
