The Grassman is Ohio’s own version of Bigfoot: a tall, hairy, upright creature said to live in the state’s eastern hills, strip-mined land and overgrown fields. Its name supposedly comes from the large grass “dens” it is said to build and from reports of it in tall grass. The most famous case linked to it is the “Minerva Monster” of August 1978, when a family near the village of Minerva told sheriff’s deputies that a hairy, foul-smelling creature had stared in their kitchen window. The story made the front page of the Canton newspaper four times, and it is still the centerpiece of Ohio Bigfoot lore.[1][2]

Where the name comes from
“Grassman” is an Ohio name, and its origins are hazy. In Bigfoot Encounters in Ohio: Quest for the Grassman (2006, revised from a 1997 edition), Christopher Murphy, Joedy Cook and George Clappison trace the term back at least to the early twentieth century. They say it described creatures seen in the tall grass of Ohio’s open country and was also used to frighten children: “the Grassman will get you.” Their book collects Ohio reports dating from 1869 to 2004.[3]
Later writers explain the name by the creature’s supposed habits: building large dens out of grass and even eating tall field grass. Those claims come from researchers and enthusiasts rather than from any documented find, and they have become part of the legend through repetition.[1]
The Minerva Monster, August 1978
The case that made the Grassman famous took place on the night of 20 August 1978, at the Cayton family’s home on Lincoln Street SE in Paris Township, near Minerva in Stark County. Herbert Cayton was working the midnight shift. At home were his wife, Evelyn, their daughters Rebecca Manley and Vicki Keck, son Howe, and a family friend, Scott Patterson. According to the accounts gathered at the time, the family first saw something looking in the kitchen window. Then a car’s headlights picked out a figure outside. They described it as about six feet tall, covered in thick hair and weighing perhaps 300 pounds. When it moved toward them, they fled indoors. Evelyn Cayton loaded a .22 rifle.[4]
The witnesses reported a powerful smell, like ammonia or rotten eggs. Mrs. Cayton said the creature seemed to make a protective gesture toward “two smaller things” with it. Another daughter, Mary Ackerman, reported seeing it again two days later, and over the following days there were further reports along Route 30 and Liberty Church Road.[4]
The investigation
Stark County Sheriff’s Deputy James Shannon took the report seriously. He interviewed about ten people and, with four other deputies, searched the area for six or seven hours using Army-surplus Jeeps and horses. Near the family’s chicken coop, searchers found part of a skull, thought to be from a cow or another large animal, and tufts of fur. The fur and skull were sent to Malone College in Canton for examination. A local hospital declined to look at the skull, and its whereabouts are now unknown.[4]
The Repository in Canton put the story on its front page four times, starting with the headline “Deputies seek 6-foot beast.” Later headlines reported that the beast was still out there and that strange noises and odors persisted, and on 24 August the paper announced a stakeout. Five days after the first sighting, a photographer from Cuyahoga Falls, John Nutter, reported seeing a bear in the area; his photograph was fuzzy, and he later said he was not sure it was a bear. No creature was ever caught.[4]
In 2015 the filmmaker Seth Breedlove made the case the subject of Minerva Monster, the first documentary from his company Small Town Monsters, with interviews from members of the Cayton family, Deputy Shannon and a former Akron Beacon Journal reporter. It premiered at the Ohio Bigfoot Conference and was shown in Minerva on a “Minerva Monster Day.” A local reviewer called it well made but noted that it included no skeptical voices.[2]
Other Ohio hotspots
- Salt Fork State Park, Guernsey County. Ohio’s largest state park is the center of modern Ohio Bigfoot interest. The local researcher Don Keating collected more than 36 reports from the park from the mid-1980s on and started an annual Bigfoot conference there in 2005, now billed as the longest-running in the world. In 2012, USA Today listed Salt Fork among the ten “Squatchiest” places in America.[5]
- Perry County. The Travel Channel series Mountain Monsters hunted the “Grassman of Perry County” near New Straitsville in a June 2013 episode, and returned to it in later seasons, giving the name national exposure.[1]
- The Hocking Hills and other parks in southeastern Ohio host Bigfoot festivals and night hikes, and the creature has become a staple of local tourism.[1]
What could explain the Grassman?
The most important real animal in this story is the American black bear. Black bears were wiped out in Ohio by about 1850 through habitat loss and unregulated hunting. A few wanderers began returning from Pennsylvania and West Virginia as early as the 1930s, and sightings grew in the late twentieth century. According to the Ohio Department of Natural Resources, 80% to 98% of confirmed sightings each year since 1993 have been in eastern Ohio, the same part of the state as Minerva, Salt Fork and Perry County. In 2025 Ohio recorded a record 537 bear reports in 69 counties, 289 of them confirmed, and breeding females are now established in the northeast. Most of the bears are young males wandering far from home, exactly the kind of animal that turns up where no one expects it.[6]
In 1978 bears were still rare in Ohio, so a family in Stark County would have had little reason to expect one. That makes a misidentified bear a reasonable possibility in the Minerva case, especially given the photographer’s report of a bear in the area days later. It does not prove that a bear was responsible, and the Caytons’ description of a creature looking in the window is hard to square with a casual sighting. But it is a much simpler explanation than an undiscovered primate.
- Bears. Black bears stand upright to look around and can walk short distances on their hind legs. A national statistical study in 2024 found that Bigfoot reports rise with black bear numbers. See our Bigfoot entry.
- Other animals and smells. Dogs, deer, and the smell of skunk or rotting carcasses can all contribute to a frightening nighttime encounter.
- Social contagion. Front-page coverage, stakeouts and search parties make further sightings almost inevitable, as with the Grafton Monster and the Beast of Bray Road.
- Hoaxes. No hoax has been shown in the Minerva case, but costumes and fake tracks are well documented elsewhere in Bigfoot history.
No body, bone, clear photograph or confirmed DNA sample of a Grassman has ever been produced. The supposed grass dens have never been shown to be the work of anything other than people, deer, wind or other animals. As with Bigfoot generally, the evidence consists of sincere but unverifiable sightings.
Our assessment
The Grassman is best understood as Ohio’s regional branch of the Bigfoot legend, with a local name and one genuinely well-documented scare at its center. The Minerva case deserves credit for having real witnesses, a serious police response and contemporary newspaper coverage. But the evidence collected that summer was lost, nothing has been confirmed since, and the region has been steadily recolonized by an animal that can stand upright, smell strongly and frighten a family at night: the black bear.

Correction note (October 2026): This entry was rewritten from documented sources. An earlier version said the Minerva creature had glowing eyes and was seen eating discarded food, described Native American traditions of the Grassman and nineteenth-century footprint reports, and stated that it builds primitive nests, all without sources.
