Maybe I should say a few things before I get lynched.
The first thing is that even though I behave suspiciously I do it in a way too obvious manner, no criminal would ever do that, why? Obviously because you don't want to get lynched on the 3rd round and then be told that you were the most obvious criminal.
Second thing is that while the rest was on a bandwagon I always chose one single target I thought was criminal and didn't change my vote (In the first round I chose Jinhong, and tried to save krudda with some vote moves). In the last game it was Seventy7X who is in my opinion incredibly suspicious. Murderer would be the first to jump on a bandwagon.
Given that Seventy7X was the first person who said that the most talkative people are probably criminals, we should apply that on him in reverse, and he seemed to be very quiet not making any enemies the whole game.
In short, I don't believe people who are too perfect such as Seventy7X and so I proceed to vote for him. Also I believe the 9 drawn on the image means 9 symbols in name of the killer.
EDIT: + there is no real evidence that I'd be the killer except that, erm, I "behaved suspiciously".
