Dummy, when he “told you” that other inmates beat him up, did he say anything about pneumonia?
Oh no wait a second, pneumonia happened many months later. After he was detained second time, in different city after trying to run off to Hungary. Oops.
You can’t even get basic timeline right, never mind present any sort of serious evidence he was physically assaulted at the second detention facility or poisoned.
In his communication to his sister he is clearly talking about very serious health problems that required invasive procedure to resolve. Yes, of course people sometimes die from that.
