Given the facts of his obesity, decades of tobacco use and steady alcohol consumption in combination with a persistent expression of vitriol and complaint about the world at large it is astonishing he did not die 10 years ago
These are perfect examples & situations to kill someone, that way no one will question his death, just saying.......we will never know, but like you stated, he probably died by natural causes......you still have to do an autopsy.
No he did not "probably" die of natural causes - he did die of natural causes - saying probably immediately vaults u into Illini's category
