I believe Jeffery Dahmer also had Narcisstic Personality Disorder. Here is another one like him and why there was such a concentrated manhunt to find him. Dahmer killed animals as well. Magnotta filmed his animal killings.
Narcissistic personality disorder is a condition in which people have an inflated sense of self-importance and an extreme preoccupation with themselves.
