The Mad Gasser of Mattoon
Phantom Attacks in Illinois and the 1944 Mystery
In September 1944, the quiet town of Mattoon, Illinois, was gripped by a series of unsettling events that quickly became the focus of local and national attention. Residents reported strange gas attacks in their homes, leading to symptoms like nausea, breathing difficulties, and even temporary paralysis. The assailant, whom the newspapers dubbed “the Mad Gasser of Mattoon,” was never identified, turning the incidents into a puzzling and eerie chapter of Illinois history.
The Mad Gasser of Mattoon remains one of the most mysterious alleged criminals in American folklore, with reports of phantom attacks causing widespread panic and confusion. Over several nights, dozens of Mattoon citizens claimed to have been targeted by an invisible prowler, sparking speculation, police investigations, and a flurry of news coverage.
Despite numerous theories and investigations, the truth behind the Mad Gasser was never uncovered, leaving behind only questions and speculation. The strange events in Mattoon continue to invite curiosity, making this case a lasting mystery that still intrigues both locals and those interested in unsolved phenomena.
Background of the Mad Gasser Phenomenon
A series of mysterious gas attacks unsettled Mattoon, Illinois, in 1944, leading to public fears, police investigations, and national headlines. Reports focused on an unknown assailant dubbed the "Mad Gasser" or "Phantom Anesthetist," whose actions are still debated today.
Origins of the Mad Gasser Reports
The first widely publicized incident occurred on August 31, 1944. A local Mattoon resident reported smelling a strange, sweet odor in her home and experiencing nausea and paralysis. Similar reports increased quickly throughout the next two weeks.
Within 12 days, at least 33 separate accounts emerged of residents smelling noxious gases and experiencing dizziness, vomiting, and even temporary loss of motor skills. Victims often described seeing a shadowy figure near their homes, but no clear suspect was ever identified.
Police responded to each incident, but they found little physical evidence of gas or an intruder. As reports grew, local newspapers began to use the term "Mad Gasser," and the story gained traction beyond Illinois.
Historical Context in Mattoon, Illinois
Mattoon in 1944 was a small, tight-knit community of about 15,000 residents. The country was in the midst of World War II, which fueled anxiety and fear of chemical warfare and enemy saboteurs.
Residents were already on high alert, as reports of gas attacks and air raids had circulated across the nation. Emergency drills and warnings were part of daily life, contributing to a climate of tension.
During the Mad Gasser incidents, officials and citizens questioned whether the attacks were the work of a local criminal or a byproduct of wartime paranoia. The absence of concrete evidence left many feeling increasingly anxious.
The Phantom Anesthetist Rumors
The "Phantom Anesthetist" or "Anaesthetic Prowler" became a local legend almost overnight. Rumors described a masked figure using specialized equipment to disperse anesthetic gases through windows or doors.
Local newspapers intensified speculation with headlines and sketches, featuring theories about chemical devices or medical backgrounds for the attacker. Some reports claimed to see footprints or tools left near victims' homes, but these clues led nowhere.
Authorities debated whether the reports reflected a real, external threat or a case of mass hysteria, given the lack of physical evidence and the widespread psychological stress of the time. The legend of the Mad Gasser persists in Mattoon lore.
Timeline of the Mattoon Incidents
A wave of mysterious gas attacks struck Mattoon, Illinois, in 1944, causing widespread confusion and fear. Documented reports highlight a series of events with specific victims, key dates, and rising public panic.
Initial Gassings and Key Dates
Mattoon's strange affliction began in early September 1944, though some sources place the first reports as late as the night of August 31. Residents described an overpowering sweet odor inside their homes, followed by symptoms like nausea, dizziness, and temporary paralysis. These incidents were soon nicknamed the work of the “Mad Gasser of Mattoon.”
The attacks largely occurred at night and seemed to target homes at random. Over a dozen cases were reported in just the first week. People often awoke in the early hours struggling to breathe or unable to move their legs.

The quick succession of reported cases led authorities to launch an investigation, but no perpetrator was caught.
August 31, 1944: The Beulah Cordes Case
The incident involving Beulah Cordes is widely cited as the earliest documented case. On the evening of August 31, 1944, she and her family noticed a strange odor entering their Mattoon home. Beulah reported numbness in her legs and partial paralysis after inhaling the unknown gas.
Her husband, unable to locate the source, searched the property but found only an open window and a faint chemical smell. Neighbors reported similar experiences, increasing suspicion that this was not an isolated event.
This case stood out for its detailed account and the severity of symptoms. The Cordes incident marked the beginning of what became a series of related complaints and gave rise to the term “Mad Gasser” in news coverage.
Escalation and Widespread Panic
Following the Cordes event, similar reports poured in from other Mattoon neighborhoods. By September 12, newspaper articles indicated 33 separate incidents within just under two weeks. Symptoms were generally consistent: people described sweet or sickly odors, nausea, and temporary loss of muscle control.
The outbreak sparked public hysteria. Many residents armed themselves or formed patrols, convinced an attacker stalked the streets at night. Police increased nighttime patrols and advised families to keep windows closed.
Rumors fueled anxiety further, as each new report received front-page attention. Despite the widespread alarm and continuing searches, no physical evidence of gas or a suspect was ever conclusively discovered.
Reported Symptoms and Victim Accounts
Residents of Mattoon in 1944 described a series of unsettling and physical symptoms after experiencing mysterious nighttime attacks. Accounts detail patterns of sudden illness, distinctive smells, and a range of physical effects reported by multiple individuals.
Paralysis and Temporary Effects
Numerous victims said they experienced sudden partial paralysis shortly after encountering the gas or odor. Many described a rapid loss of feeling in their legs or partial numbness, sometimes making it difficult or impossible to move.
Aline Kearney, one of the earliest victims, described paralysis as feeling like an “electric shock.” Temporary paralysis usually lasted anywhere from a few minutes up to half an hour before subsiding.
Reports consistently mention that these effects were temporary, with sensation and movement returning after the initial shock wore off. Despite the alarming nature of these incidents, no long-term physical damage was documented. Victims’ descriptions often shared similarities in the onset and duration of symptoms.
Nausea, Vomiting, and Coughing
Nausea and vomiting were frequently reported following the exposure. Individuals recalled becoming suddenly sick, sometimes within minutes of detecting a strange smell in their home. Some suffered bouts of vomiting, especially in more severe encounters.
Coughing fits were another common reaction, often beginning soon after breathing in the unknown substance. These coughing episodes sometimes lingered for hours after the initial exposure.
Multiple cases referenced a combination of these symptoms, with coughing and nausea occurring together. The intensity of these effects seemed to vary depending on proximity to the source or the length of exposure.
Descriptions of the Sweet Odor
A notable and repeated detail in victim accounts is the presence of a distinct, sweet-smelling odor just before symptoms began. The scent was often described as “sickly sweet” or chemical-like, noticeable enough to alert residents that something was wrong.
Many victims stated that this odor filled entire rooms or houses, causing immediate discomfort. Some claimed the odor was so overpowering it woke them up at night. Its presence almost always preceded the onset of symptoms, making it a key aspect of the reported attacks.
The specific character of this sweet smell remains a point of speculation. Witnesses could not agree on the exact nature of the scent, but almost all indicated that it was unfamiliar and unpleasant under the circumstances.
Strange Smell and Other Sensations
Beyond the paralyzing and nauseating effects, victims frequently mentioned a generalized “strange smell” that was difficult to describe. This scent often lingered even after attacks ended, with some detecting residual odors hours later.
Other sensations included tingling or prickling feelings on the skin and in the mouth. People also mentioned unusual dryness or irritation in their throats immediately after breathing the air.
A summary list of other recorded sensations:
Tingling in limbs
Dry mouth or throat irritation
Weakness or dizziness
Burning eyes or slight headaches
These non-specific symptoms added to the widespread anxiety in Mattoon, as many residents feared further exposure to the mysterious gas. For several weeks, these reports fueled local concern and prompted both police investigations and medical examinations.
Investigation and Evidence
Authorities reacted to the reports of strange gas attacks in Mattoon, taking multiple steps to understand the incidents. Community anxiety increased as both the police and local media became highly active, and several types of evidence were examined for leads.
Police Response and Local Media Coverage
Police took the initial reports seriously, patrolling the affected neighborhoods and interviewing those who claimed to be attacked. Mattoon police increased their presence and organized patrols, but no suspect was arrested.
Local newspapers, such as the Daily Illini, published frequent articles about the gas attacks. Headlines often highlighted the growing number of incidents, reporting that by September 12, 1944, at least 33 people claimed to have been affected by the gas. The media coverage was intensive and sometimes speculative.
This coverage likely contributed to widespread concern and may have amplified community anxiety. Police updates and interviews with witnesses were common features in print, keeping public attention sharply focused on the unfolding story.
Searches for a Prowler
Residents and police conducted late-night searches for what was often described as a "prowler." Many believed someone was sneaking around homes and releasing gas through open windows or screens.
Officers were dispatched to areas following new reports, searching backyards and alleys for any sign of the suspect. Citizens armed themselves and formed watch groups, convinced an attacker was at large.
Despite these efforts, no one was ever apprehended at the scene. Various individuals reported glimpses of a shadowy figure fleeing, but clear identification proved elusive. The search for the supposed prowler yielded no decisive results.
Physical and Forensic Evidence
Physical evidence reported included sliced window screens and footprints found near some homes. Such findings suggested a person might have attempted to gain entry, but none of the evidence led to an arrest or solid conclusion about the attacker.
Victims described symptoms after exposure, such as nausea or temporary paralysis. However, police and doctors rarely retrieved any gas residue or samples to analyze, which made conclusive forensic investigation difficult.
The lack of clear forensic evidence complicated the case. Items like rags or handkerchiefs found at some sites were tested, but none revealed the presence of unusual chemicals. The evidence remained primarily anecdotal and circumstantial.
Theories Surrounding the Gas Attacks
Investigators and researchers have proposed several theories to account for the strange events in Mattoon during 1944. Explanations range from chemical agents and gas leaks to psychological and sociological factors.
Chemical Substances and Possible Anesthetics
Some witnesses described a sweet, sickly odor during the suspected gas attacks. This led authorities and scientists to consider toxic chemicals such as chloroform, ether, or chloropicrin as possible agents. These substances have sedative or irritant effects and were used historically as anesthetics or pesticides.
Doctors noted that the symptoms—including numbness, dizziness, vomiting, and occasional paralysis—could potentially result from exposure to these chemicals. However, no conclusive physical evidence, such as contaminated objects or lingering odors, was ever recovered from the scenes.
Speculation centered on whether an individual with access to chemical knowledge and resources, such as a chemist or laboratory worker, could have dispersed anesthetic vapors through open windows. There is no direct proof of deliberate chemical attacks. Yet, the theory remains plausible due to descriptions of both the odor and symptoms.
The Role of the Pilot Light and Gas Leaks
Some authorities suggested that pilot lights from stoves and faulty household gas lines might explain the symptoms. If a gas leak occurred while a pilot light extinguished, airborne anesthetic gases like ether or even fuel gases could have caused dizziness, nausea, or mild chemical burns.
Residents in 1944 often relied on coal gas or natural gas for cooking. Poor ventilation and older appliances increased the possibility of accidental exposure. Investigations in multiple homes, however, failed to detect abnormal gas levels or sources of accidental leaks during or after reported incidents.
While the pilot light theory offers a natural explanation, it does not account for the repeated reports clustered in a short period, or for cases where multiple people in the same house were affected simultaneously. There were also inconsistencies in reported symptoms and gas company inspections rarely found evidence of malfunction.
Phantom or Anaesthetic Prowler Hypothesis
A key line of inquiry focused on the possibility of a living "Mad Gasser"—a prowler who sprayed anesthetics or irritants through windows. Some residents claimed to glimpse a shadowy figure fleeing after an attack. This led to considerations that a person with basic chemistry knowledge could replicate ether or chloroform's effects by dispersing the chemicals.
The anaesthetic prowler theory became widely circulated in local newspapers and captured national attention. It fits a pattern seen in other reported "gas attacks" and urban legends from the early 20th century.
Despite increased community patrols and police investigations, no suspect was ever apprehended and no spraying devices were recovered. The lack of any material evidence led skeptics to doubt the existence of a human perpetrator.
Psychogenic Illness and Mass Hysteria
Medical professionals and psychologists later proposed that the Mattoon events were best explained by psychogenic illness—a situation where anxiety and suggestion cause real physical symptoms in otherwise healthy individuals. The mass hysteria theory points out that most attacks occurred during heightened wartime stress and after initial news reports gained traction.
Symptoms described by victims—shortness of breath, faintness, numbness—are also consistent with panic responses and can spread rapidly in a close-knit community. No objective evidence (such as chemical residues) was found at any scene, further supporting this interpretation.
Group fear, media amplification, and the power of suggestion likely fueled the perception of a prowler and gas attacks, even in the absence of poison gases or a physical assailant. This explanation is consistent with similar events recorded throughout history.
Media Influence and Public Reaction
Coverage of the Mad Gasser events in 1944 was shaped by the way information spread in Mattoon and beyond. The press played a direct role in fueling the anxiety that swept through the community, and national coverage added layers of notoriety and speculation.
Impact of Local Newspapers
Mattoon's local newspapers were central in distributing early reports of the supposed gas attacks. The first major story appeared on September 1, 1944, after the wife of a local cab driver recounted her encounter with the “Mad Gasser.” The use of vivid headlines and regular updates kept public attention fixed on each new incident.
These reports focused not only on victims' descriptions but also included speculation from local authorities and residents. Accusations of negligence or inaction by police were printed alongside details from frightened citizens. This coverage had the effect of amplifying fear and reinforcing the community's sense of emergency.
By continually publishing statements from officials and newly alleged victims, the papers unintentionally fostered a feedback loop of anxiety among readers. Updates were frequent, giving the impression that attacks were ongoing and widespread, even as evidence remained unclear.
National Attention and Sensationalism
Once the story moved beyond Mattoon, larger news agencies picked up the narrative. National newspapers and wire services summarized and sensationalized the episodes, using language that portrayed the city as under siege. Headlines highlighted the mysterious nature of the attacks while downplaying investigations that pointed toward mass hysteria.
The involvement of national media intensified scrutiny on local police and contributed to rumors spreading outside of Illinois. Some outlets quoted medical professionals suggesting psychological explanations, but these were often overshadowed by the more dramatic aspects of the mystery.
This broader coverage led to a spike in reported sightings and symptoms, even outside Mattoon. The national lens often distorted local realities, as communities across the United States briefly imagined themselves at risk of similar “phantom attackers.”
Cultural References and War of the Worlds
The Mad Gasser case quickly entered popular culture due to its uncanny resemblance to stories in science fiction and radio dramas. In 1938, just six years earlier, the broadcast of Orson Welles’ “War of the Worlds” had famously triggered mass panic. Several commentators and scholars have drawn connections between the reaction to the Gasser scare and the night of the radio play.
Parallels included the rapid spread of fear, public belief in a mysterious attacker, and the role of media in sustaining anxiety. Like the “War of the Worlds” incident, the Gasser affair became a case study for how communities can respond to frightening news, regardless of available physical evidence.
These cultural associations further embedded the events into the American imagination. Both incidents are frequently referenced in studies on mass hysteria and media influence, serving as reminders of the powerful relationship between news reporting, entertainment, and public perception.
Social and Psychological Implications
The Mad Gasser incidents highlight how fear can rapidly spread through a community and show how social psychology helps explain mass reactions to unexplained threats. These events also left lingering effects on Mattoon's sense of security and collective memory.
Community Anxiety and Panic
In late summer 1944, Mattoon residents described feeling sudden anxiety and fear as reports of gas attacks circulated. Several people claimed to experience symptoms such as nausea, coughing, and even temporary paralysis, often after detecting a “sickly sweet” odor.
Rumors and media coverage intensified the panic. Local newspapers published updates almost daily, which led more residents to report similar symptoms, even with little or no evidence of a real attack.
Key patterns of mass hysteria and psychogenic illness appeared. The community’s shared anxiety became self-reinforcing, with worry and suspicion spreading faster than any physical hazard.
Social Psychology of the Events
Social psychology offers insight into how the Mad Gasser story unfolded. Collective behavior—how people act when reacting to a common threat—played a major role. The uncertainty surrounding the incidents made residents more susceptible to suggestion.
Groups primed by anxiety often misinterpret ambiguous smells or sounds as signs of danger. In Mattoon, suggested symptoms became “contagious,” a phenomenon known as mass psychogenic illness.
Authorities struggled to separate credible reports from imagined ones. The inability to catch the perpetrator, or even confirm the attacks, created an environment where fear spread as a social phenomenon, not just as a response to a physical threat.
Long-Term Effects on Mattoon Residents
The episodes left a mark on the city’s collective psyche long after the panic faded. Many residents became more cautious about unusual odors or unexplained illnesses.
A lasting sense of mistrust developed toward both outsiders and even neighbors. Some people questioned the reliability of official explanations, which increased rumors and suspicion.
Stories about the Mad Gasser remain part of Mattoon’s local folklore. The events are still cited as an example of how communities can be affected by mass anxiety and psychogenic episodes, shaping both memories and local identity for generations.
Legacy of the Mad Gasser of Mattoon
The Mad Gasser of Mattoon remains one of the most puzzling local phenomena in Illinois history. The events left a lasting impression both on the community of Mattoon and on later discussions of mass hysteria and unexplained urban mysteries.
Enduring Mystery and Modern Perspectives
The identity of the Mad Gasser was never confirmed, and no one was ever apprehended for the suspected gas attacks. Police and local authorities investigated thoroughly, but physical evidence was scarce.
Some contemporary researchers and historians suggest the events in Mattoon resemble classic cases of mass hysteria. Symptoms often appeared after people heard about previous incidents, supporting the idea of psychological contagion rather than a physical assailant.
Today, the case is referenced in discussions about group psychology and the spread of fear in small communities. It is sometimes compared to other episodes of unexplained panic, such as phantom attacker scares in other towns.
Influence on Urban Legends and Popular Culture
The Mad Gasser of Mattoon has become a fixture in Illinois folklore. The case is often cited as an example of how urban legends can evolve from real but ambiguous events.
A variety of books, articles, and documentaries have re-examined the Mattoon scare, bringing it to broader public attention. Podcasts and local museums occasionally feature it, maintaining its presence in popular conversation.
Lists of American unsolved mysteries sometimes include the Mad Gasser, highlighting its ongoing fascination. The story has influenced discussions about how rumors and anxieties can shape collective memory, particularly in small communities like Mattoon.
