"Copycat killer" redirects here. For the EP, seeCopycat Killer.
Acopycat crime is a criminal act that is modeled after or inspired by a previouscrime. It notably occurs after exposure to media content depicting said crimes, and/or a live criminal model.
According to a study, copycat crime is a social phenomenon that persists and is prevalent enough to have an impact on the whole criminal landscape, primarily by influencing criminal tactics as opposed to criminal motive or the emergence of criminal traits.[1]
The copycat effect is the alleged tendency of sensational publicity about violent murders or suicides to result in more of the same through imitation.[2]
The term was first coined in the early 20th century, following crimes inspired byJack the Ripper. Due to the increase of replicated crimes,criminologists soon began to believe that media coverage played a role in inspiring other criminals to commit crimes in a similar fashion, and even for non-criminals to begin committing crimes when they otherwise might not have done so.[3]
A 2004 book written byLoren Coleman calledThe Copycat Effect describes the effect that the media has on crimes and suicides, which are inspired by crimes that have been widely covered across the media. Coleman's view on the media is that the constant coverage of these events, rather than the events with a positive message, gives these criminals a type of fame. The five minutes of fame, book or movie that is dedicated to these criminals provokes other individuals with a tendency to behave in a similar way. Due to this type of fame, the "copycat effect" takes place.[2]
The US documentary television seriesCopyCat Killers (2016–20) investigates murders that appear to be based on Hollywood films.
People who mimic crimes seen in the media (especially in news and violent movies) are more likely to have prior criminal records, severe mental health problems, or histories of violence. This suggests that the effect of the media is indirect (more affecting criminal behavior) rather than direct (directly affecting the number of criminals).[4] However, that indirect influence that the media has on the individual could possibly give them an idea of how to commit a crime. The type of reaction that the media coverage gives crimes can determine the path another criminal might take. This is because most copycat criminals are intent on the shock value of their actions. They commonly want to do something that will cause a high media coverage because of the attention that they will get, as well as the horror a crime may create. For example, if going on a shooting rampage in a public space causes this attention (because of previous incidents), then an individual with the tendency to commit the crime will more likely take that path.[5]
The norms, heroes, anti-heroes and the spectacles of the time and place also influence how a crime is committed. One modern example might include dressing as a villain and going to a public place armed; occasionally, individuals replicate their favorite movie or TV show scene. Conversely, before modern media, such crimes might be associated with religious beliefs or phenomena in the natural environment. In both scenarios, it is the public interest that sparks what crime might be committed.[5]
Some researchers hold the view that the interaction between violent media content and the emotional development of an individual play a role in copycat behaviors. Individuals who are less emotionally developed will more likely commit the crimes that they see on TV. Characteristics such as demographic (age and sex), criminal factors (mental/personality disorders, failure in human bonding/lack of identity, social isolation and alienation) and relationship to media (trust in media,media literacy, identification with the perpetrators seen in media), mixed with media characteristics and cultural-environmental factors influences the copycat behavior in individuals. Media characteristics include the blur between fantasy and reality, positive response to violence and crime, and how the crime is being committed. Cultural-environmental factors include the cultural view of fame and crime, reliance to the media for information, and moral panics. Offenders most likely to be influenced by these characteristics are usually under the age of 25.[6] However, these claims are an object of an ongoing debate inresearch on the effects of violence in mass media.
Apart from these, the findings of another study showed that instead of a first-time violent offender, a copycat offender is more inclined to be a professional criminal who commits property-related offences. Since the social background aspects affecting copycat crimes have not been established, it is still uncertain how exactly media coverage and the behaviour of copycat crimes are related.[1]
American writer and cryptozoologistLoren Coleman and authorZeynep Tufekci have suggested that copycat crimes can be prevented through a number of means, including: the use of carefully selected, non-sensationalistic language on the part of law enforcement and the media when communicating news of crimes to the public; avoiding the release of details on both the methods of crimes and the name of any suspects; avoiding the perpetuation of cliches and stereotypes about criminals and the causes of their behavior; emphasis on the effect of the crimes on the victims and their loved ones; and including protective factors like helplines when publishing stories on such crimes.[7]
Various criminal acts have been inspired by many television shows, movies, books as well as other criminals. A list of a few crimes that have been a result of the copycat effect are:
The television showBreaking Bad has been suspected of inspiring a number of crimes. The series depictsWalter White, a high school chemistry teacher with cancer who begins making and selling drugs to obtain money for securing his family's financial future. Some of the most notable include the following:
Blue colored methamphetamine, seemingly inspired by Walter White's meth, has been found by law enforcement across the United States; the first reports of such meth was inKansas City, Missouri in 2010,[8] while by 2014, it had reached the show's main setting ofNew Mexico.[9]
In 2013, a 27-year-oldNine Mile Falls man, Jason Hart, was found guilty of strangling his girlfriend to death, and then usedsulfuric acid in a plastic tub to dispose of the body. The incident had many similarities to various scenes inBreaking Bad, where Walter andJesse Pinkman dispose of bodies in a similar fashion. It was later found out that he had been a fan ofBreaking Bad.[8][10]
In 2015, a 31-year-oldLiverpool man, Mohammed Ali, was sentenced to eight years in prison after trying to buy 500 mg ofricin, a toxin which plays a major part in the show's plot, on adarknet market.[13] In his testimony, he stated he was merely curious as to what he could buy off the dark web and as "[he] had been watchingBreaking Bad, [he] just had ricin in [his] mind."[14]
In Canada,Mark Twitchell was arrested in 2008 for the attempted murder of one man and the successful murder of another. He was convicted of the latter crime only in 2011, but he documented his efforts to become a serial killer and is a fan of the television showDexter.
On March 4, 2025, 15-year-old Reed R. Gelinskey was arrested and subsequently charged with first-degree intentional homicide for the death of his mother inCaledonia, Wisconsin.[15] Gelinskey stated that he developed the plan to kill his parents after watching the "shotgun scene"[a] from theNetflix limited seriesMonsters: The Lyle and Erik Menendez Story.[16]

Scream: A 24-year-old man, Thierry Jaradin, stabbed a young girl, Alisson Cambier, 30 times; similar to the way the victim was stabbed in the movie. He had been wearing the Ghostface costume, and later confessed that he had planned the murder in a similar way to the movie.[17] On September 22, 2006, Cassie Jo Stoddart, a high school student, was murdered by her classmatesBrian Draper and Torey Adamcik in her aunt and uncle's house inPocatello,Idaho,United States.[18] The perpetrators claimed that they were inspired to murder Stoddart by Scream, which led to them being nicknamed"The Scream Killers". Adamcik and Draper recorded documentary-style videos about how they were horror movie fans, especially Scream, and wanted to reenact a similar murder in real life.
Fight Club: There have been many incidents inspired by the movie. One of the incidents occurred in 2009 during theMemorial Day weekend inNew York City. Bombs were set off in various locations supposedly representing their oppression. Kyle Shaw was found guilty, and was himself a member of the local fight club.[17]
Saw: InSalt Lake City two teenage boys were turned in after being overheard planning the kidnapping, torture, and murder of several individuals who in their estimation needed to be taught a lesson. The pair had set up cameras so as to record their killings. InTennessee, two girls were charged with phone harassment after leaving a 52-year-old woman voicemail stating they had taken possession of her friend, were about to release a toxic gas, and the voicemail recipient had to choose between risking her own life to save her friend's or let her friend die.[17]
The Dark Knight:The movie's depiction of the Joker has inspired several crimes. In 2010, aWisconsin man assaulted his cousin and girlfriend, dressed as the Joker, when he found them sleeping together. In 2009, a young girl attacked her teacher with a razor blade. Her face had been painted in a similar way to the Joker.[17] The2012 Aurora, Colorado shooting, which took place during a screening ofthe film's sequel, is often mistaken for a Joker copycat crime due to misinformation in early reporting.[19]
Several movies, includingBasic Instinct,American Psycho,Casablanca andCatch Me If You Can, inspiredLuka Magnotta to commit the 2012 murder ofConcordia University studentJun Lin.[20] Magnotta recorded the murder of the student whom he had recently met onCraigslist and also posted the video online. On the video,New Order's "True Faith" can be heard playing in the background, which can also be heard inAmerican Psycho. Jun Lin was stabbed multiple times while being tied up on the bed, in the same way that Johnny Boz was tied up onBasic Instinct's main character Catherine's bed. One item Magnotta used to murder Jun Lin was a screwdriver, which was painted white to make it look like the ice pick Catherine used to kill Johnny Boz. Above the bed, Magnotta carefully hung a poster of the movieCasablanca, which he threw away after the murder. After the murder, Magnotta fled toParis (which is also an important location inCasablanca), claiming that an individual named Manny forced him first to kill cats and then Jun Lin; Manny was the name of Catherine's fiancé in Basic Instinct. In 2014 Magnotta was captured inBerlin and flown back to Canada.[21] While in Europe, Magnotta used a false passport in the name of Kirk Trammel, which is another reference toBasic Instinct's main character Catherine Trammel. On the footage of the interrogation, Magnotta sits cross-legged while smoking a cigarette to complete his homage toBasic Instinct. Around 2010, when Magnotta first started uploading videos online of him killing kittens, he used different aliases and accounts. On one account, he posted the movieCatch Me If You Can, in which Leonardo DiCaprio is on the run from theFBI.[citation needed]
KGF: Chapter 2:Spree killer Shivprasad Dhurve, who bludgeoned three security guards to death inSagar andBhopal,Madhya Pradesh, claimed after his arrest that he was inspired by the character Rocky Bhai and because he "wanted to be famous".[22]
Asghar the Murderer:Hoshang Amini, who murdered a total of 67 people inVaramin from 1954 to 1962, said in interviews after his arrest that he was inspired by Asghar's murder spree. Like Asghar, Amini also predominantly targeted young boys.[23]
Zodiac Killer: In the late 1960s, near San Francisco, an unidentified man murdered at least five victims and wounded two more, also sending taunting letters and codes to the media. Twenty years laterEddie Seda attacked victims in a similar manner inNew York City, killing his victims with a homemade gun. He left similar notes at the scene of the crime, and also sent cryptic letters to the police. Unlike the Zodiac Killer, Seda was eventually caught because of the fingerprints that he had left behind on the notes.[24] Seito Sakakibara, the perpetrator of theKobe child murders used the symbol of The Zodiac Killer as his signature. He was nicknamed the "Japanese Zodiac Killer". Serial killerEdward Edwards infamously killed couples in lover's lanes as allusions to the Zodiac, author John Cameron even suggesting Edwards himself was the Zodiac[citation needed].
Gerald and Charlene Gallego: From 1978 to 1980, the married couple murdered ten victims across three states in a series of crimes dubbed the "Sex Slave murders". Over a decade later, from 1996 to 1997, another couple, James Daveggio and Michelle Michaud, committed a series of rapes and one murder in similar fashion to the Gallegos. They had even purchased the couple'strading cards in a serial killer-themed deck as well as the bookThe Sex Slave Murders, which detailed crimes committed by the Gallegos.[25][26]
September 11 attacks: On January 5, 2002, four months after 9/11, a 15-year-old boy named Charles Bishop, heavily inspired by the 9/11 attacks, committed the2002 Tampa Cessna 172 crash, in which he stole and drove a small Cessna plane and purposely crashed it into the side of theBank of America Tower in Tampa, Florida. In his suicide note, Bishop showed support for Osama Bin Laden. The crash itself injured no one and only damaged one of the rooms in the building, the only casualty being Bishop.
The Dnepropetrovsk maniacs: On 5 April 2011, twoRussian youths, Artyom Anoufriev and Nikita Lytkin, known as theAcademy maniacs were arrested in connection with six murders and attacks on residents in Akademgorodok inIrkutsk. The attacks, which involved a mallet and knife, began in December 2010. Both were arrested after a video recording showing a female body being mutilated with a knife was found on a camera belonging to Lytkin's uncle, who had become suspicious. According to media reports, the youths were influenced by reading about the Dnepropetrovsk maniacs on the Internet. A psychiatric examination found them sane, and they told doctors they chose weak people as their victims. On 2 April 2013, Anoufriev was sentenced to life imprisonment and Lytkin to 24 years in prison.[27][28][29][30][31]
Jack the Ripper: TheAlmería Ripper, an unidentified Spanish serial killer who murdered between five and at least ten prostitutes inAlmería between 1989 and 1995, is thought have been influenced by Jack.[32] In 2008, Derek Brown, 48, was found guilty of killing two young women in a similar way as the Ripper. He had targeted the two women, one a prostitute and the other a street vendor, because he believed that the two would not have been noticed missing. The two bodies were never found, but it is said that he may have dismembered the women in his bathtub and later disposed of the bodies.[24]

In case,Stella Nickell was found guilty of tampering with Excedrin, which caused the death of two individuals, as well as her husband.[24]
Dunblane massacre: On March 13, 1996, Thomas Hamilton, 43, killed 16 children and one teacher at Dunblane Primary School before committing suicide. On April 28 of that same year,Martin Bryant committedanother mass shooting at Port Arthur in Tasmania, killing 35 people and injuring 23 before his arrest. According to his lawyer, Bryant was motivated in large part by media coverage of the Dunblane shooting, particularly the attention given to the perpetrator.[33]
Timothy McVeigh: theOklahoma City bombing was intended to be emulated by a teen militia, theLords of Chaos, in a firebombing arson at a Coca-Cola factory. the Oklahoma City bombing was also the inspiration for the Columbine shooting, which was intended to be a bombing.
Jokela High School massacre: TheKauhajoki school shooting occurred on 23 September 2008, atSeinäjoki University of Applied Sciences inKauhajoki, a town in the former province ofWestern Finland. The gunman, 22-year-old culinary arts student Matti Juhani Saari, shot and fatally injured ten people with a semi-automatic pistol, before shooting himself in the head. He died a few hours later inTampere University Hospital, Saari was heavily inspired by Pekka Eric Auvinen the gunman behind the Jokela shooting, Saari is known to have started dressing and behaving similarly to Auvinen in the period between the two shootings.[34] Saari even made a pilgrimage toJokela High School prior to his massacre. Finnish police first stated that Saari "very likely" knew Auvinen,[35] but in the final investigation no proof of that was found.
Vladimir Ionesyan: Between 2014 and 2015,Anushervon Rakhmanov murdered seven people inMoscow,Russia in a manner resembling Ionesyan's. He would even use the same method as the former to enter each victim's house: by presenting himself as an employee of Mosgaz who was sent to check the pipes.[42]
Lam Kor-wan: After watching a videotape covering his crimes, habitual thiefLuo Shubiao, who had committed a murder in 1977 but was not apprehended for it at the time, committed 18 copycat murders inGuangzhou,China from 1990 to 1994.
