John William Chardon, a 73-year-old prisoner, died from coronary atherosclerosis with severe calcified atheroma causing >70% stenosis of coronary arteries. He presented with dizziness on 21 October 2020, which initially resolved with normal vital signs and normal gait. He returned minutes later with recurrent dizziness, vomited, complained of chest pain, then rapidly became unresponsive.
