In the "Law & Order: Special Victims Unit" episode "Uncivilized," the investigation of a young boy's murder first leads to a convicted pedophile. However, the true killers turn out to be teenagers with no clear motive.
The episode is based on the infamous case of Leopold and Loeb case in Chicago that shocked the country in 1924. Nathan Leopold, 19, and Richard Loeb, 18, were both brilliant young men from wealthy families. They were also lovers obsessed with the idea that they were above moral law because they each represented the Nietzschean "superman." So, in what was essentially an intellectual experiment, they wanted to conduct the perfect crime. They concocted an elaborate scheme to kidnap and kill a boy, demand ransom and get away scot-free.
After kidnapping and killing 14-year-old Bobby Franks, Leopold and Loeb dumped his body in a culvert several miles outside of the city and dropped a ransom note in the mail. But their "perfect" plan didn't work out. The next day, someone happened to find the body and tell police. A pair of glasses found near the body also linked the crime to Leopold. The boys soon confessed and explained how and why they killed Franks. Leopold explained to one reporter, "A thirst for knowledge is highly commendable, no matter what extreme pain or injury it may inflict upon others" [source: Baatz].
