> It turns out that Google's knowledge graph algorithm somehow falsely associated my photo with the Wikipedia article about the serial killer. Which is also surprisingly strange because my name isn't special or unique at all; there are literally hundreds of other people with my name, and despite of all that, my personal photo ended up being associated with a serial killer. I can't really explain to myself how this happened, but it's weird. In any case, I am now in the process of reporting this Knowledge Graph bug to Google.
I believe that there is a simpler explanation.
The Wikipedia article is there in that side box because it is the top hit for "hristo georgiev" on Google's main search page. The picture is there because it is the top hit for "hristo georgiev" on Google's image search page.
