When Yusif Osman collapsed with chest pains, his cellmate at the Otay Mesa immigrant detention center called for a guard. Instead of coming into the cell to check on Osman, the guard called the nurse and asked if Osman had any medical problems. The nurse said no. So the guard walked away. The cellmate yelled again and another guard came by. Again, he called the nurse. This time, she asked they bring him to the center clinic. It took guards 40 minutes to get a wheelchair to Osman's cell. He was barely alive when he got to the clinic and died soon after. Doctors who reviewed his case said he might still be alive today if he'd received prompt treatment for heart failure.
