Bing has definitely not turned him into a serial killer. The main issue is associating his photo (wrongly) with the serial killer Wikipedia article. Bing is not doing that and instead showing a box with the Wikipedia article (without a photo, as it is in Wikipedia) and, separately, other results.

The name is not unique - I personally know two people named that and in the whole country, there are probably hundreds. He has also stated that.

According to the article, the name is not unique at all (for his people at least).

bing is not showing his picture though
