When Morgan Geyser, 15, was sentenced to 40 years in a mental hospital on February 1, 2018 for her role in the brutal attempted murder of a friend, renewed attention was turned toward the bizarre 2014 case. What would compel two pre-teen girls with bright futures to plot such a gruesome stabbing—solely to appease a fictional-paranormal figure dubbed "Slender Man"? How had the line between truth and fiction grown so violently blurred?
Of course, Morgan Geyser and her co-conspirator, Anissa Weier, aren't the only people to plot real-life crimes based on fictional characters, films or scenarios. "To copy such a gruesome sequence isn't completely unknown," says Kevin Hoffin, a criminologist and lecturer at the Birmingham City University in the United Kingdom. "A lot of research has been completed linking violent media to real-world violence, and there is as much evidence to confirm it as to deny it. I think of human...propensity [for] criminality like a Venn diagram: There has to be a crossover point for a number of features to profile a potential killer, not just one or two."
Below are a few other cases in which life cruelly imitated art.
Daniel Gonzalez: 'The Freddy Krueger Killer'
In 2004, a young British man named Daniel Gonzalez went on a random killing spree in London and Sussex. Later dubbed the "Freddy Krueger Killer" after the villain from the 1980s A Nightmare on Elm Street horror franchise, Gonzalez told police he wanted to be "remembered as a famous serial killer," according to BBC News.
Using various sized knives (like Krueger wore on his hands), Gonzalez killed four people and injured two others in a series of random attacks. The most tragic part of all? The attacks likely could have been prevented. His mother, Lesley Savage, said they had sought help for his mental-health issues in the past, but their pleas were not taken seriously: "Every time we asked for help for Daniel…we were told we would have to wait for a crisis to occur before he could get the help he needed."
Gonzalez himself also appealed for help from his doctor, writing to his general practitioner: "Please, please help me, this is very urgent. I really really do need medical help to find the correct environment and the correct medication. I need to take this in a controlled hospital environment."
Watch: Three men in Queens were so inspired by the heist from the movie "The Town," that they decided to re-enect the scene almost shot-for-shot in a real life robbery - but made one fatal error that lead the cops right to them.
At trial, his defense claimed he was schizophrenic and committed the murders at the urging of voices in his head. He was sentenced to multiple life sentences, but committed suicide with a makeshift blade at Broadmoor Hospital in 2007. (He had previously tried to commit suicide by "ferociously" biting himself.)
While Hoffin acknowledges Gonzalez's disturbing past, he doesn't believe it excuses his heinous behavior. "Gonzalez was described as a dark and troubled boy, but...many 'dark and troubled' teenagers do not go on to commit violent crimes," Hoffin says.
