Маттун газы: 1940 жылдарғы құпиялы оқиға

Supposed serial burglar known for their use of an alleged anaesthetic gas, or, case of mass hysteria
The Mad Gasser of Mattoon (also known as the "Anesthetic Prowler," the "Phantom Anesthetist," or simply the "Mad Gasser") was the name given to the person or people believed to be responsible for a series of apparent gas attacks that occurred in Mattoon, Illinois, during the mid 1940s. More than two dozen separate cases of gassings were reported to police over the span of two weeks, in addition to many more reported sightings of the suspected assailant. The gasser's supposed victims reported smelling strange odors in their homes which were soon followed by symptoms such as paralysis of the legs, coughing, nausea and vomiting. No one died or had serious medical consequences as a result of the gas attacks. Police remained skeptical of the accounts throughout the entire incident. Many reported gassings had simple explanations, such as spilled nail polish or odors emanating from animals or local factories. Nevertheless, local newspapers ran alarmist articles about the reported attacks and treated the accounts as fact. Another report, made some weeks later, described the gasser as being a female dressed as a man. The Gasser had also been described as carrying a flit gun, an agricultural tool for spraying pesticide, which he purportedly used to expel the gas.

The first of the 1944 gasser incidents occurred at a house on Grant Ave., Mattoon, on August 31, 1944. Urban Raef was awakened during the early hours of the morning by a strange odor. He felt nauseated and weak, and suffered from a fit of vomiting. Suspecting that he was suffering from domestic gas poisoning, Raef's wife tried to check the kitchen stove to see if there was a problem with the pilot light, but found that she was partially paralyzed and unable to leave her bed. Later that night (some contemporary accounts refer to the time as the morning of the following day), a similar incident was also reported by a young mother living close by. She was awakened by the sound of her daughter coughing but found herself unable to leave her bed. of Marshall Avenue, Mattoon, reported smelling a strong, sweet odor around 11:00 pm. At first she dismissed the smell, believing it to be from flowers outside of the window, but the odor soon became stronger and she began to lose feeling in her legs. Kearney panicked and her calls attracted her sister, Mrs. Ready, who was in the house at the time. Mrs. Ready also noticed the odor, and determined that it was coming from the direction of the bedroom window, which was open at the time. The police were contacted, but no evidence of a prowler was found. At around 12:30 am, Bert Kearney, Aline Kearney's husband (a local taxi driver who had been absent during the time of the attack), returned home to find an unidentified man hiding close to one of the house's windows. The man fled and Kearney was unable to catch him. Kearney's description of the prowler was of a tall man dressed in dark clothing, wearing a tight fitting cap. This description was reported in the local media, and became the common description of the gasser throughout the Mattoon incident. In addition to the cloth, a skeleton key, described as looking "well used," was reportedly found on the sidewalk adjacent to the porch, along with a large, almost empty, tube of lipstick. The cloth was analyzed by the authorities, but they found no chemicals on it that could explain Beulah Cordes' reaction. During this period, there was also an increase in physical evidence of attacks being reported, ranging from footprints allegedly being discovered underneath windows to tears being found in window screens.

There are three primary theories about the Mattoon Mad Gasser incident: mass hysteria, industrial pollution, or an actual physical assailant. The events have also been written about by authors on the paranormal.

Almost two weeks after the Mattoon attacks began, the local Commissioner of Public Health, Thomas V. Wright, announced that there had undoubtedly been a number of gassing incidents, but that many instances were likely due to hysteria: residents hearing of alarming events, and then panicking when confronted by an out of place odor or a shadow at the window; Wright stated: and went on to form the basis for several subsequent studies of the phenomena of mass hysteria. Most of the physical symptoms recorded during the Botetourt and Mattoon incidents (including choking, swelling of mucus membranes, and weakness/temporary paralysis) have all been suggested symptoms of hysteria. Some experts believe that the mass hysteria was fueled by the headline in the Mattoon Journal Gazette, "Mrs. Kearney and Daughter First Victims," which assumed there would be more attacks.

On September 12, Chief of Police Cole told a press conference that odors and symptoms reported may have been the result of pollutants or toxic waste released by nearby industrial plants, and speculated that carbon tetrachloride or trichloroethylene, both of which have a sweet odor and can induce symptoms similar to those reported by purported gasser victims, may have been the substance released. In response to Cole's statement, Atlas Imperial, the primary company implicated in this affair, released a statement of its own saying that their facility had only five gallons of carbon tetrachloride in stock, which was contained in firefighting equipment. Atlas Imperial officials also denied that any quantities of trichloroethylene (an industrial solvent used by Atlas) could be responsible for sickness in the town, reasoning that it would have taken significant quantities of the chemical to sicken the townspeople, and that factory workers would have experienced similar symptoms long before anybody outside of the factory was affected.
