Hiu Lui Ng was a detainee in custody of US Immigration and Customs Enforcement when he started to complain of severe back pain. After months of asking for medical help and being accused of faking he died of rampant undiagnosed cancer.
During the time of his incarceration he grew so weak he could not walk. They did finally start giving him pain medication until he could no longer stand in line to receive them. Other detainees had to help him eat and go to the toilet.
A Federal judge finally ordered the warden take him to the hospital for an MRI. The test revealed he was riddled with cancer. He died five days later. His wife and kids couldn't visit for three days until their social security numbers were verified.
