Bloody Benders

In October 1870, five families of spiritualists homesteaded in and around the township of Osage in northwestern Labette County, approximately 7 mi (11 km) northeast of where Cherryvale would be established seven months later. One of the families was John Bender Sr. and John Bender Jr., who registered 160 acres (65 ha) of land located adjacent to the Great Osage Trail, which was then the only open road for traveling further west. After a cabin, a barn with a corral, and a well were built, in the fall of 1871, Elvira Bender and daughter Kate arrived, and the cabin was divided into two rooms by a canvas wagon-cover. The Benders used the smaller room at the rear for living quarters, while the front room was converted into a "general store" where a few dry goods were sold. The front section also contained the kitchen and dining table, where travelers could stop for a meal or even spend the night. Elvira and Kate Bender also planted a 2-acre (0.81 ha) vegetable garden and apple orchard north of the cabin.[1][2][3]

John Bender, Sr. was around 60 years old and spoke very little English. When he did speak it, it was so guttural that it was usually unintelligible. According to the May 23, 1873 edition of The Emporia News, he was identified with the name of William Bender. Elvira Bender, who also allegedly spoke very little English, was 55 years of age and was so unfriendly that her neighbors took to calling her a "she-devil".

John Bender Jr. was around 25 years old, handsome with auburn hair and a mustache, and spoke English fluently but with a German accent. John was prone to laughing aimlessly, which led many to consider him a "half-wit". Kate Bender, who was around 23, was cultivated and attractive and spoke English well with very little accent. A self-proclaimed healer and psychic, she distributed flyers advertising her supernatural powers and her ability to cure illnesses. She also conducted séances and gave lectures on spiritualism, for which she gained notoriety for advocating free love. Kate's popularity became a large attraction for the Benders' inn. Although the elder Benders kept to themselves, Kate and her brother regularly attended Sunday school in nearby Harmony Grove.

The Benders were widely believed to be German immigrants. No documentation or definitive proof of their relationships to one another, or where they were born, has ever been found. John Bender, Sr. was from either Germany or the Netherlands and is thought by some to have been born John Flickinger. According to contemporary newspapers, Elvira was born Almira Hill Mark (often misreported as "Meik") in the Adirondack Mountains; she married Simon Mark, with whom she claimed to have had 12 children. Later, she married William Stephen Griffith. Elvira was suspected of murdering several husbands, but none of these rumors were ever proven. Kate was believed to be Elvira's fifth daughter. Some of the Benders' neighbors claimed that John and Kate were not brother and sister, but actually husband and wife.

From those who knew them and have written about them, we gather the following: "The old man was a repulsive, hideous brute, without a redeeming trait, dirty, profane and ill-tempered." "Old Mrs. Bender was a dirty old Dutch crone. Her face was a fit picture of the midnight hag that wove the spell murderous ambition about the soul of Macbeth." "Young Bender, seen when excited, recalled the grave-robbing hyena at once to mind." "Kate proclaimed herself responsible to no one save herself." She professed to be a medium of spiritualism, and delivered lectures on that subject. In her lectures she publicly declared that murder might be a dictation for good; that in what the world might deem villainy, her soul might read bravery, nobility, and humanity. She advocated "free love," and denounced all social regulations for the promotion of purity and the prevention of carnality, which she called "miserable requirements of self-constituted society." She maintained carnal relations with her brother, and boldly proclaimed her right to do so, in the following words found in her lecture manuscript: "Shall we confine ourselves to a single love, and deny our natures their proper sway?...Even though it be a brother's passion for his own sister, I say it should not be smothered."[4]

In May 1871, the body of a man named Jones, who had his skull crushed and his throat cut, was discovered in Drum Creek. The owner of the Drum Creek claim was suspected, but no action was taken. In February 1872, the bodies of two men were found who had the same injuries as Jones. By 1873, reports of missing people who had passed through the area had become so common that travelers began to avoid the trail.[1][2][3]

The area was already widely known for "horse thieves and villains", and vigilance committees often "arrested" some for the disappearances, only for them to be later released by the authorities. Many innocent men under suspicion were also run out of the county by these committees.[5]

In the winter of 1872, George Newton Longcor and his infant daughter, Mary Ann, left Independence, Kansas, to resettle in Iowa and were never seen again. In the spring of 1873, Longcor's former neighbor, Dr. William Henry York, went looking for them and questioned homesteaders along the trail. Dr. York reached Fort Scott, and on March 9 began the return journey to Independence but never arrived home.

Dr. York had two brothers: Colonel Ed York living in Fort Scott, and Alexander M. York, a member of the Kansas State Senate from Independence who, in November 1872, had been instrumental in exposing U.S. Senator Samuel C. Pomeroy's bribery of state legislators in his bid for re-election. Both knew of William's travel plans and, when he failed to return home, an all-out search began for the missing doctor. Colonel York, leading a company of some fifty men, questioned every traveler along the trail and visited all the area homesteads.

On March 28, 1873, Colonel York arrived at the Benders' inn with a Mr. Johnson, explaining to them that his brother had gone missing and asking if they had seen him. They admitted Dr. York had stayed with them and suggested the possibility that he had run into trouble with Indians. Colonel York agreed that this was possible and remained for dinner.[1][3] On April 3, Colonel York returned to the inn with armed men after being informed that a woman had fled from the inn after being threatened with knives by Elvira Bender. Elvira allegedly could not understand English, while the younger Benders denied the claim.[5]

When York repeated the claim, Elvira became enraged, said the woman was a witch who had cursed her coffee, and ordered the men to leave her house, revealing for the first time that "her sense of the English language" was much better than was let on. Before York left, Kate asked him to return alone the following Friday night, and she would use her clairvoyant abilities to help him find his brother. The men with York were convinced the Benders and a neighboring family, the Roaches, were guilty and wanted to hang them all, but York insisted that evidence must be found.[5][6]

Around the same time, neighboring communities began to make accusations that the Osage community was responsible for the disappearances, and a meeting was arranged by the Osage township in the Harmony Grove schoolhouse. The meeting was attended by 75 locals, including Colonel York and both John Bender Sr. and John Bender Jr. After discussing the disappearances, including that of William York, it was agreed that a search warrant would be obtained to search every homestead between Big Hill Creek and Drum Creek.[1][2][3] Despite York's strong suspicions regarding the Benders since his visit several weeks earlier, no one had watched them, and it was not noticed for several days that they had fled.[5]

Bender Inn the day after the gravedigging began

Three days after the township meeting, Billy Tole was driving cattle past the Bender property when he noticed that the inn was abandoned and the farm animals were unfed. Tole reported the fact to the township trustee, but because of inclement weather, several days lapsed before the abandonment could be investigated. The township trustee called for volunteers, and several hundred turned out to form a search party that included Colonel York. When the party arrived at the inn they found the cabin empty of food, clothing, and personal possessions.[7]

A bad odor was noticed and traced to a trap door underneath a bed, nailed shut. After opening the trap, the empty room beneath, 6 feet (1.8 m) deep and 7 feet (2.1 m) square at the top by 3 feet (0.9 m) square at the bottom, was found to have clotted blood on the floor. The stone slab floor was broken up with sledgehammers but no bodies were found, and it was determined that the smell was from blood that had soaked into the soil. The men then physically lifted the cabin and moved it to the side so they could dig under it, but no bodies were found.[7]

They then began to probe the ground around the cabin with a metal rod, especially in the disturbed soil of the vegetable garden and orchard, where Dr. York's body was found later that evening, buried face down with his feet barely below the surface. The probing continued until midnight, with another nine suspected grave sites marked before the men were satisfied they had found them all and retired for the night. Digging resumed the following morning; another eight bodies were found in seven of the nine suspected graves, while one was found in the well, along with a number of body parts. All but one had had their heads bashed with a hammer and their throats cut, and it was reported in newspapers that all had been "indecently mutilated". The body of a young girl was found with no injuries sufficient to cause death. It was speculated that she had been strangled or buried alive.[7]

A Kansas newspaper reported that the crowd was so incensed after finding the bodies that a friend of the Benders named Brockman, who was among the onlookers, was hanged from a beam in the inn until unconscious, revived and interrogated as to what he knew, then hanged again. After the third hanging, they released him and he staggered home "as one who was drunken or deranged".[8] A Roman Catholic prayer book was found in the house with notes inside written in German, which were later translated. The texts read "Johannah Bender. Born July 30, 1848," "John Gebhardt came to America on July 1 18??," "big slaughter day, Jan eighth", and "hell departed."[7]

Word of the murders spread quickly, and more than three thousand people, including reporters from as far away as New York City and Chicago, visited the site. The Bender cabin was destroyed by souvenir hunters who took everything, including the bricks that lined the cellar and the stones lining the well.[1][2]

State Senator Alexander York offered a $1,000 ($21,342 as of 2021) reward for the Bender family's arrest. On May 17, Kansas Governor Thomas A. Osborn offered a $2,000 ($42,683 as of 2021) reward for the apprehension of all four.

It is conjectured that when a guest would stay at the Benders' bed and breakfast inn, the hosts would give the guest a seat of honor at the table which was positioned over a trap door that led into the cellar. With the victim's back to the curtain Kate would distract the guest, while John Bender or his son would come from behind the curtain and strike the guest on the right side of the skull with a hammer. The victim's throat was cut by one of the women to ensure death. The body was then dropped through the trap door. Once in the cellar, the body would be stripped and later buried somewhere on the property, often in the orchard.[1][2] Although some of the victims had been quite wealthy, others had been carrying little of value on them, and it was surmised that the Benders had killed them simply for the sheer thrill.[2]

Testimony from people who had stayed at the Benders' inn and had managed to escape before they could be killed appeared to support the presumed execution method of the Benders. William Pickering said that when he had refused to sit near the wagon cloth because of the stains on it, he was threatened with a knife by Kate Bender, whereupon he fled the premises. A Catholic priest claimed to have seen one of the Bender men concealing a large hammer, at which point he became uncomfortable and quickly departed.[2]

Two men who had traveled to the inn to experience Kate Bender's psychic powers stayed on for dinner but had refused to sit at the table next to the cloth, instead preferring to eat their meal at the main shop counter. Kate then became abusive toward them, and a short while later the two Bender men emerged from behind the cloth. At this point, the customers began to feel uneasy and decided to leave, a move that almost certainly saved their lives.[9]

More than a dozen bullet holes were found in the roof and sides of the cabin. The media speculated that some of the victims had attempted to fight back after being hit with the hammer.[5]

Detectives following wagon tracks discovered the Benders' wagon, abandoned with a starving team of horses with one of the mares lame, just outside the city limits of Thayer, 12 mi (19 km) north of the inn. It was confirmed that in Thayer the family had bought tickets on the Leavenworth, Lawrence & Galveston Railroad for Humboldt. At Chanute, John Jr. and Kate left the train and caught the MK&T train south to the terminus in Red River County near Denison, Texas. From there, they traveled to an outlaw colony thought to be in the border region between Texas and New Mexico. They were not pursued, as lawmen following outlaws into this region often never returned.[1]

One detective later claimed that he had traced the pair to the border, where he had found that John Jr. had died of apoplexy.[2] Ma and Pa Bender did not leave the train at Humboldt but instead continued north to Kansas City, where it is believed they purchased tickets for St. Louis, Missouri.[1]

Several groups of vigilantes were formed to search for the Benders. Many stories say that one vigilante group actually caught the Benders and shot all of them but Kate, whom they burned alive. Another group claimed they had caught the Benders and lynched them before throwing their bodies into the Verdigris River. Yet another claimed to have killed the Benders during a gunfight and buried their bodies on the prairie. No one ever claimed the $3,000 reward ($64,025 as of 2021), however.

The story of the Benders' escape spread, and the search continued on and off for the next 50 years. Often, two women traveling together were accused of being Kate Bender and her mother.[10]

In 1884, it was reported that John Flickinger had committed suicide in Lake Michigan.[3] Also in 1884, an elderly man matching Pa Bender's description was arrested in Montana for a murder committed near Salmon, Idaho, where the victim had been killed by a hammer blow to the head. A message requesting positive identification was sent to Cherryvale, but the suspect severed his foot to escape his leg irons and bled to death. By the time a deputy from Cherryvale arrived, identification was impossible due to decomposition. Despite the lack of identification, the man's skull was displayed as that of "Pa Bender" in a Salmon saloon until Prohibition forced its closure in 1920 and the skull disappeared.[11] Whether John Flickinger was really John Bender is unknown.

Several weeks after the discovery of the bodies, Addison Roach and his son-in-law, William Buxton, were arrested as accessories. In total, 12 men "of bad repute in general" would be arrested, including Brockman. All had been involved in disposing of the victims' stolen goods with Mit Cherry, a member of the vigilance committee, implicated for forging a letter from one of the victims, informing the man's wife that he had arrived safely at his destination in Illinois.[7] Brockman would be arrested again 23 years later for the rape and murder of his own 18-year-old daughter.[8]

On October 31, 1889, it was reported that a Mrs. Almira Monroe (a.k.a. Mrs. Almira Griffith) and Mrs. Sarah Eliza Davis had been arrested in Niles, Michigan (often misreported as Detroit) several weeks earlier for larceny. They were released after being found not guilty, but were then immediately re-arrested for the Bender murders. According to the Pittsburgh Dispatch, the daughter of one of the Benders' victims, Mrs. Frances E. McCann, had reported the pair to authorities in early October after tracking them down. Mrs. McCann's story came from dreams that she had about her father's murder, which she discussed with Sarah Eliza. The women's identities were later confirmed by two Osage township witnesses from a tintype photograph. In mid-October, Deputy Sheriff LeRoy Dick, the Osage Township trustee who had headed the search of the Bender property, arrived in Michigan and arrested the couple on October 30, following their release on the larceny charges. Mrs. Monroe resisted, declaring that she would not be taken alive, but was subdued by local deputies.

Mrs. Davis claimed that Mrs. Monroe was Ma Bender, but that she herself was not Kate, but her sister Sara; she later signed an affidavit to that effect, while Monroe continued to deny the identification and in turn accused Sarah Eliza of being the real Kate Bender. Deputy Sheriff Dick, along with Mrs. McCann, escorted the pair to Oswego, Kansas, where seven members of a 13-member panel confirmed the identification and committed them for trial. Another of Mrs. Monroe's daughters, Mary Gardei, later provided an affidavit claiming that her mother (then Almira Shearer), under the name of Almira Marks, was actually serving two years in the Detroit House of Corrections in 1872 for the manslaughter of her daughter-in-law, Emily Mark. Records of the incarceration back up this affidavit. At her hearing, Mrs. Monroe denied any knowledge of Shearer or the manslaughter charge and remained incarcerated with her daughter. Originally scheduled for February 1890, the trial was held over to May. Mrs. Monroe now admitted she had married a Mr. Shearer in 1872 and claimed she had previously denied it, as she did not want the court to know that her name was Shearer at that time and that she had a conviction for manslaughter. Their attorney also produced a marriage certificate indicating that Mrs. Davis had been married in Michigan in 1872, the time when several of the murders were committed. Eyewitness testimony was given that Mrs. Monroe was Ma Bender. Judge Calvin dismissed Mary Gardei's affidavit as she was a "chip off the old block"; he found that other affidavits supporting Gardei's were sufficient proof that the women could never be convicted, however, and he discharged them both. The affidavits and other papers are missing from the file in LaBette County, so further examination is impossible. A number of researchers question the ready acceptance of the affidavit's authenticity and suggest that the county was unwilling to accept the expense of boarding the two women for an extended period. While the two women were certainly criminals and liars, as their own defense attorney admitted, the charges were weak and many people doubted their identification as the Benders.[1][11][12][13][14][15][16]

• 8-9) December 1872: George Newton Longcor and his 18-month-old daughter, Mary Ann. Contemporary newspapers reported his name as either "George W. Longcor" or "George Loncher", while Mary Ann is similarly reported as being either eight years old or 18 months old. According to the 1870 census, George and his wife, Mary Jane, were neighbors of Charles Ingalls and family in Independence, while his wife's parents lived two houses away. Following the deaths of his infant son, Robert, from pneumonia in May 1871 and his 21-year-old wife, Mary Jane (née Gilmore), following the birth of Mary Ann several months later, George was likely returning to the home of his parents, Anthony and Mary (Hughes) Longcor, in Lee County, Iowa. In preparation for his return to Iowa, George had purchased a team of horses from his neighbor, Dr. William Henry York, who later went looking for George and was also murdered; both were veterans of the Civil War. $1,900 (2021: $40,549) missing. The daughter was thought to have been buried alive, but this was not proven. No injuries were found on her body, and she was fully clothed, including mittens and hood. Both were buried together in the apple orchard.

• 16-19) December 1872: During the search, the bodies of four unidentified males were found in Drum Creek and the surrounds. All four had crushed skulls and throats cut. One might have been Jack Bogart, whose horse was purchased from a friend of the Benders after he went missing in 1872.
• 20) May 1873: Dr William York. $2,000 (2021: $42,683) missing. Buried in the apple orchard.

By including the recovered body parts not matched to the bodies found, the finds are speculated to represent the remains of more than 20 victims. With the exception of McKenzie and York,[17] who were buried in Independence; the Longcors, who were buried in Montgomery County; and McCrotty, who was buried in Parsons, Kansas, none of the other bodies were claimed, and they were reburied at the base of a small hill 1 mile (1.6 km) southeast of the Benders' orchard, one of several at the location now known as "The Benders Mounds".[5][18] The search of the cabin resulted in the recovery of three hammers: a shoe hammer, a claw hammer, and a sledgehammer that appeared to match indentations in some of the skulls. These hammers were given to the Bender Museum in 1967 by the son of LeRoy Dick, the Osage Township trustee who headed the search of the Bender property.[18] The hammers were displayed at the Bender Museum in Cherryvale, Kansas from 1967 to 1978, when the site was acquired for a fire station. When attempts were made to relocate the museum it became a point of controversy, some locals objecting to the town being known for the Bender murders. The Bender artifacts were eventually given to the Cherryvale Museum, where they remain in a wall-mounted display case.[1][2] A knife with a four-inch tapered blade was reportedly found hidden in a mantel clock in the Bender house by Colonel York. In 1923 it was donated to the Kansas Museum of History by York's wife but is not on display; still bearing reddish-brown stains on the blade, it can be seen upon request.[18]

A historical marker describing the Benders’ crimes is located in the rest area at the junction of U.S. Route 400 and U.S. Route 169 north of Cherryvale.[18]

The Ingalls family, made famous in the books and television series Little House on the Prairie, lived near Independence, and Laura Ingalls Wilder mentioned the Bender family in her writing and speeches. In 1937 she gave a speech at a book fair, which was later transcribed and printed in the September 1978 Saturday Evening Post and in the 1988 book A Little House Sampler. She mentioned stopping at the inn, as well as recounting the rumors of the murders spreading through their community. She alleged that her father, "Pa Ingalls", joined in a vigilante hunt for the killers, and when he spoke of later searches for them she recalled, "At such times Pa always said in a strange tone of finality, 'They will never be found.' They were never found and later I formed my own conclusions why."[19][20] Some have cast doubt on the story, saying that Laura would have been only 4 when her family moved away from the area, and that the Benders were exposed in 1873, two years after the Ingalls left.

• Anthony Boucher's 1943 short story "They Bite" is set at a western oasis where "Carkers" once used to kill and eat travelers; the hypothesis is floated that they were the Benders (who, in this telling, ate their victims) after leaving Kansas. There are still man-eating somethings at the oasis, and the hypothesis is that the Benders linked up with some sort of supernatural power in the desert and became nearly immortal.[21][22]
