At least two more suspects have now been arrested in the Aug. 18 slaying of a pizza restaurant owner in the Edgewood neighborhood, WTOP’s Mark Segraves reports. One suspect, Shanika Robinson, had already been arrested in the killing of Pizza Mart co-owner Shahabuddin Rana a few weeks ago, but now her brother, Leon Robinson, has also been taken into custody and charged with first degree murder. Segraves also tells DCist that a third suspect, whose name we still don’t know, has been arrested in the time since this initial report. Police allege that Rana was killed after a false marriage arrangement between Shanika Robinson and Rana’s brother fell apart. Rana had been paying Robinson $500 a week to be married to his brother so that he could get a green card, according to police, but at some point Rana stopped the payments. Further complicating the sordid case is the death of Terrance Green, a D.C. police officer who committed suicide earlier this month after he was subpoenaed to appear before a grand jury in the case.
