Heartbreaking story. They talk a lot about the possibility of bacterial infection but it was not consistent with the blood tests. It seems he just got unlucky (although should have had a Chest X-Ray).

Trying to reframe it in a coding analogy, there were a few abnormal logs maybe an exception or two but the coder was unable to figure it out and these exceptions happen all the time and so pushed to live anyway. Due to resource allocation issues they were pulled to a different job. Then the site crashed. Just awful.
