This is not a complicated case.
Homaidan Al-Turki is an inmate at Limon Correctional Facility in Colorado. He was in pain. His pain was so severe that he was unable to stand and was vomiting. Mary Robinson, the nurse on duty at the time, refused to treat him, telling him to take it up in writing with the doctor who would be around in the morning. Eventually he passed out, woke up still in pain, and passed two kidney stones.
Crisis averted, but there was still the matter of hours of untreated pain. Hence, his lawsuit against Robinson for deliberate indifference.
