I'm very sorry for your loss mate.
At any rate, I'd not jump to any conspiracy related conclusion until an autopsy is performed. You are going to give yourself into an unnecessary
amount of stress during an already stressful time for you.
Pay your respect, mourn, don't worry about conspiracy theories during this. People die of heart attacks all the time, it's very common, due to our
unhealthy habits. People get bad colds all the time, and it's the season for it.
