From Schizophrenia to Sadism: Decoding the Minds of Serial Killers through Handwriting Analysis

Handwriting Characteristics of Serial Killers

Analysts in this field have pointed out specific traits that may appear in the handwriting of serial killers. These traits include unusual spacing between words, broken letters, use of fabricated characters, unusual punctuation, block letters, and irregular letter sizing. For example, many known serial killers, such as Ted Bundy, John Wayne Gacy, and Jeffrey Dahmer, exhibited these traits in their handwriting.

Ted Bundy: Sadism Reflected in Handwriting

Ted Bundy, a notorious serial killer, murdered at least 20 women between 1974 and 1978. Analysts, including Anna Korn, believe his sadistic and schizophrenic traits were evident in his handwriting.

Bundy’s handwriting showed a tendency for exaggerated, large loops in the lower sections of letters like "Y" and "J," a feature possibly indicating a schizophrenic personality. His handwriting was nearly illegible due to sharp angles, narrow letters, and compressed spacing—traits that, according to graphologists, point to a schizophrenic and ruthless personality.

John Wayne Gacy: Signs of Violence in the “Killer Clown’s” Handwriting

John Wayne Gacy, an American killer known as the "Killer Clown," murdered at least 33 boys and young men between 1972 and 1978.

Handwriting analysts noted traits like excessive ink usage and heavy writing in his handwriting, suggesting a strong need to satisfy desires and an inclination toward violence. The distinct formation of small letters in the lower zone and his tendency to lean left, along with heavy ink usage, indicate that Gacy possessed an angry personality with sadistic and violent tendencies.

Jeffrey Dahmer: Schizophrenic Tendencies Reflected in Handwriting

Jeffrey Dahmer, famously known as the "Milwaukee Cannibal," murdered seventeen men and boys from 1978 to 1991.

His handwriting displayed various schizophrenic characteristics, including a rightward slant, wide spacing between words, and broken letters. These traits reflect Dahmer’s reclusive and schizoid personality. Analysts believe Dahmer’s handwriting reveals his ruthless and psychopathic nature.

David Berkowitz: A Killer with Disturbed Handwriting

David Berkowitz, known as the "Son of Sam" and the ".44 Caliber Killer," terrorized New York City between 1976 and 1977, killing six people and injuring eleven others.

His handwriting had unusual features: the beginning and end letters were written strangely, and many letters were obscured by lines. According to analysts, this suggested a tense and secretive personality. Additionally, his slow and tense writing style, according to Korn, reflected an organized, methodical, and self-reliant personality—common traits among many serial killers.

The Zodiac Killer: An Unsolved Mystery

The Zodiac Killer, whose identity remains unknown, has five confirmed victims and claims responsibility for killing 37 people.

This killer left unique handwriting and coded symbols in letters sent to the police and media. The Zodiac’s handwriting, similar to Dahmer's, included printed letters, wide spacing, and cryptic writing. These characteristics may reflect a schizophrenic personality with a tendency toward secrecy.

Can Handwriting Reveal a Killer?

Although graphology has yet to be fully accepted as a definitive scientific method, analysts believe that examining the handwriting of serial killers can reveal some of their psychological traits. These traits include slanting to the left or right, irregular spacing, unusual letters, and obscuring lines—all of which may hint at secrecy, hidden anger, and psychosis. Despite the ambiguity surrounding this method, graphology can serve as a complementary tool in understanding the personalities of killers and potentially predicting criminal behavior.
