User blog comment:CrashingCymbal/Are There Any Serial Killers/Murder Cases That You Have a Keen Interest In?/@comment-9773576-20140202080312

Josef Mengele, one of the scientists in Auschwitz during WWII, has always intrigued me. His most notable experimentation/killings were on twins...if you don't know who he is, look him up. Some sick shit you'll find there.

Other than that, the JFK assassination has always sparked my interest.
