Piecing together details from the linked article and an article linked in that article, it sounds like Snider had been assaulted in South Salt Lake City on 11/1 and taken to the hospital. The following day, 11/2, he got into some sort of dispute at the hospital, was arrested, held for a day, and then released (11/3). He was at home until he was taken to a hospital on 11/14 with pneumonia, from which he died. Putting all that together, it sounds like he ignored or was unaware of his pneumonia for a week or more. He seems to have been a bit cantankerous, so ignoring the symptoms is plausible. OTOH, based on recent personal experience *, being unaware of any symptoms until the pneumonia was serious is also plausible. Either way, his being held for a day by the police is separated from his hospitalization by 11 days, so blaming the police for his death doesn't work, due to anachronism.
* Recently, I was unaware of symptoms on a Saturday, was unusually very chilled Sunday evening, and had to be hospitalized the next day with pneumonia, for 10 days.
