==This article needs sources, badly.== 

 I work as a forensic psychologist and while I'm not a serial killer specialist I have researched the area enough to believe I would have heard of things such as the following. 

 "Some serial killers go to lengths to make their crimes difficult to discover, such as falsifying suicide notes, setting up others to take the blame for their crimes, and faking gang warfare"  

 -There are cases where I have heard of falsified suicide notes, but faking gang warfare and setting up others? Could someone provide a source here? I'll gladly accept it if that is infact true, but a source is something needed. 

 Much of the article is well written and organized but it is completely unsourced and this calls into question the credibility of much of the information here in within among readers. Editers should start adding sources to whatever piece of infomation they add. 

 Not to mention the article is extremely plain. Pictures anyone? Media pictures of serial killers aren't IP, they are public property so pretty much any one of the many pictures of serial killers available on the web could be used.
