Due to the government’s extreme restrictions on communications for minority populations in China, reports of cases like Lhamo and Tarpa’s rarely become known outside the country. This is particularly true of Driru county, where local authorities crushed peaceful protests in 2013-2014, and restrictions on basic freedom are among the most severe in the region.

United Nations standards adopted by the General Assembly set out that all death-in-custody cases should be subjected to “prompt, impartial, and effective investigations into the circumstances and causes” of the death. As the UN special rapporteur on the extrajudicial, summary or arbitrary executions has noted, since there is a presumption of state responsibility due to the custodial setting and the government’s obligation to ensure and respect the right to life, the government has to affirmatively provide evidence to rebut the presumption of state responsibility. Absent proof that it is not responsible, the government has an obligation to provide reparations to the family of the deceased.

The Chinese government also has rules dealing with deaths in custody. These require the police to “immediately conduct” an investigation into the cause of death by viewing and preserving the surveillance video of the detention cell and questioning fellow detainees, doctors, and guards, among other measures.

collective statement from UN human rights experts in June underlined the need for an independent investigation of the range of human rights violations by the Chinese government. They expressed grave concern over China’s failures to respect human rights and abide by its international obligations and recommended establishing an impartial and independent UN mechanism to monitor and report on abuses “in view of the urgency of the situations” in Hong Kong, Xinjiang, and Tibet.

“For decades Chinese officials have gotten away with detaining people without justification and mistreating them, including to the point of death,” Richardson said. “Those officials cannot be relied on to investigate these violations, creating an urgent need for independent, international investigations by UN human rights experts.”
