The undisputed King of Games
John Wayne Gacy. Gay clown
I can only think of 2 famous criminals that aren't lolcows D.B Cooper and whoever carried out the 300 million yen robbery in japan but that's probably because nothing is known about them.All of them.
I was about to say TJ Lane! His whole family situation was fucked up and his attitude during the trial was absolutely horrifying.T.J. Lane
Shot up his High School where he was then tried as an adult and plead guilty to get three life sentences. According to Wikipedia:
A couple years later he managed to escape prison but got captured a few hours later.
Anyone who throws their life away to be an asshole in Court for 15 minutes definitely qualifies as a lowcow.
