It has been five years since Ms. Zhang Sukun's youngest daughter, Gao Rongrong was tortured to death in custody. Ms. Zhang and her family had no way to find justice, and were continually harassed and mistreated by agents from the 610 Office and Domestic Security Division. Before the 2008 Beijing Olympics, agents from the Beijing State Security Department threatened Ms. Zhang and her family in Beijing. They did not allow them to appeal over Gao Rongrong's death in custody, and pressured them to agree to have her body cremated. Around October 1, 2009 National Day, agents from State Security and the police closely monitored her family, who lived in the Guangda Garden Neighborhood in Haidian District, by "guarding" their apartment door 24 hours. When President Obama visited China, "guards" were present day and night. Ms. Zhang's granddaughter tried to study abroad, but was blocked by State Security, and could not travel out of the country. On July 16, 2010, Ms. Zhang died.
