( CNN ) -- Accused Tucson gunman Jared Lee Loughner has been indicted on 49 counts including murder and attempted murder that stem from a shooting that left six people dead and critically wounded Arizona Rep. Gabrielle Giffords . A grand jury had indicted Loughner , 22 , on three counts of attempted murder , including one alleging that he tried to kill Giffords with a Glock semiautomatic handgun during an event for constituents at a Tucson grocery store in January . Giffords is currently undergoing rehabilitation at a medical facility in Houston , Texas . The new indictment , returned by a federal grand jury Thursday , includes those three charges and adds murder charges connected to the deaths of John M. Roll , a federal district judge , and Gabriel M. Zimmerman , a staff member for Giffords . He also faces charges in the deaths of Dorothy J. Morris , Phyllis C. Schneck , Dorwan C. Stoddard , and a child , referred to in the indictment as C-T G. Nine-year-old Christina-Taylor Green was among those killed in the shooting . A charge of attempted assassination of a member of Congress also is among the 49 counts . `` The deceased are not the only ones whose rights are being defended , '' U.S. Attorney Dennis K. Burke said in a news release . `` Those citizens who were peaceably assembled to speak to their member of Congress are also named victims in this indictment . '' The indictment carries a potential death sentence if convicted , Burke added , although prosecutors have not said yet whether they will seek the death penalty . `` We will seek justice for the federal officials , Judge Roll and Gabriel M. Zimmerman , and for Dorothy J. Morris , Phyllis C. Schneck , Dorwan C. Stoddard , and C-T G , '' Burke said . The alleged gunman previously had faced two murder charges in the deaths of Roll and Zimmerman , but in a procedural maneuver , prosecutors had temporarily dropped those charges , bringing them back under the superseding indictment . Loughner , who is being held by authorities in Arizona , is expected to be arraigned on the new charges March 9 in Tucson , the district attorney 's office said . Also Friday , Giffords ' office released a picture of her taken the morning of the shooting . The congresswoman is seen standing in front of the grocery store , talking to constituents identified by her office as Jim and Doris Tucker . Jim Tucker was shot twice , once in his calf and once in his collarbone , according to CNN affiliate KOLD . His wife escaped unharmed . `` I 've wondered since the very beginning , 'Why was n't I shot ? ' but I just take it as a miracle from God that I was n't , for some purpose , '' Doris Tucker has told the network .
