Koochin was diagnosed with an "inoperable and incurable" brain tumor in 2004. He had been undergoing care at Primary Children's Medical Center in Salt Lake City since September 15, 2004 when “his tumor pushed his brain stem down through the skull." Subsequently, two physicians independently determined that the child was brain dead and informed his parents that they would order life support removed within twenty-four hours. However, the parents rejected the hospital’s definition of death. Instead, relying on traditional notions of cardiopulmonary death, they obtained a restraining order to keep Koochin on a ventilator. Later, they removed the brain-dead child from the hospital. Koochin's heart ultimately stopped beating on November 19, 2004.
