Mary Bennett, a 25-year-old female grocer in Aiken County, South Carolina, spent the spring of 1946 working alongside her husband, Edward, in the small family store they ran for their community. On the night of April 28, 1946, their ordinary routine shattered when an armed man entered the grocery, turned a place of everyday commerce into a crime scene, and opened fire.
Mary was fatally shot, and Edward was mortally wounded in front of their young children, who witnessed the chaos and terror unfold in the narrow aisles of the shop. As Edward lay dying, he managed to tell those around him that “a big negro shot me and robbed me,” a brief, desperate statement that would shape the direction of the investigation and the fate of another man for years to come.
The double homicide sent a wave of fear through Aiken County. Residents knew the Bennetts as hardworking shopkeepers, and the idea that someone could walk into a family grocery, shoot a husband and wife in front of their children, and vanish into the night was almost unbearable. Under intense public pressure, Aiken County authorities launched a sweeping investigation, questioning numerous men who might fit the vague description from Edward's dying words. For more than two months, police detained and interrogated a succession of suspects, but no firm evidence emerged. Each lead faded, leaving the community still grieving, the Bennett children without their parents, and the sheriff's office under growing criticism for failing to solve such a shocking crime.
Eventually, attention turned to a local laborer named L.D. Harris, who had drifted between odd jobs in the area. Investigators learned that Harris had left for Nashville, Tennessee, shortly after the murders and that he possessed a pistol. Seeing this as a promising lead, the sheriff obtained a warrant that was nominally for the theft of his aunt's pistol but was in practice a means of hauling him back to South Carolina in connection with the Bennett killings. Harris was arrested in Nashville and transported to Aiken County without being told why he had truly been taken into custody. Once locked in the county jail, he discovered that he was suspected of the murder of the grocer and his wife, a revelation that must have been terrifying for a man with little education and no legal guidance.
What followed was not a careful search for truth but a campaign to secure a confession. Over five days, Harris was interrogated repeatedly in a small, stifling room, sometimes surrounded by multiple officers and officials. According to later accounts, he was struck in the face during questioning, threatened with a club, and warned that if he did not admit to killing the Bennetts, the officers could “get a rope and rubber hose” and he knew what that meant. Perhaps most chilling was the sheriff's threat to arrest Harris's mother unless he confessed. Illiterate, frightened, and isolated from family, friends, and counsel, Harris finally broke. On the fifth night he signed a written statement confessing to the murder of Mary and Edward Bennett, repeating words dictated to him by the sheriff rather than his own account of events.
Once the confession was obtained, the legal machinery moved quickly. In October 1946, Harris was indicted and arraigned without counsel and sent to the state penitentiary to await trial. In January 1947 he faced a jury for the Bennett murders. At trial, Harris testified that he was innocent and that he had confessed only because he was terrified by the threats and physical mistreatment he endured. Even the trial judge acknowledged that apart from the confession there was no evidence linking him to the crime. Nonetheless, the jury accepted the confession as voluntary and sufficient. Harris was convicted and sentenced to die in the electric chair for the murder of the Bennetts, and for a time it seemed that Mary's case had been legally “resolved,” with a condemned man standing in for the unknown shooter who had stormed into her family's store.
The story did not end there. Harris's attorneys appealed through the state courts, arguing that the confession had been coerced, but the Supreme Court of South Carolina upheld his conviction and death sentence. Only when the case reached the United States Supreme Court did the tide turn. In 1949, the Court reviewed the circumstances of Harris's interrogation and found that the confession was the product of sustained pressure and intimidation. The justices noted his illiteracy, the failure to inform him of his rights or provide a preliminary hearing, the days of relentless questioning in isolation, and the threats directed both at him and at his mother. In a narrow 5–4 decision, the Court ruled that the confession was involuntary and could not be used as the basis for a death sentence, effectively overturning his conviction and leading to his release. Legally, the Bennett murders were again without a proven perpetrator, and Mary's killers remained, in the eyes of the law, unidentified.
Even during the original 1946 investigation, one man had briefly come under suspicion and been questioned before slipping back into obscurity: Monroe “Blue” Hickson, a local man with a history of run-ins with the law. He was picked up around the time of the Bennett murders but was released after telling officers he had been walking to see his employer. That decision would loom large years later, when Hickson's path crossed once more with the Aiken County authorities. By 1957, Hickson had been paroled from a burglary sentence. Shortly afterward, he brutally assaulted another shopkeeper, Lucy Hill Parker, leaving her with severe head injuries. The assault prompted a broader look at Hickson's movements and habits, and investigators began to notice disturbing patterns that matched several unsolved crimes from 1946—including the attack on the Bennetts.
Confronted with these connections during questioning, Hickson began to talk. He admitted that his 1946 violence had not begun with Lucy Parker's assault but with a series of earlier attacks. Eleven days before the Bennett murders, he said, he had killed David Garrett, a storekeeper in Aiken, striking him with an axe and stealing a pistol. With that gun in hand, he then entered the Bennetts' grocery on April 28, 1946. There he shot Mary and gravely wounded Edward during a robbery, just as their children looked on. Hickson went on to confess to the September 28, 1946 murder of an elderly woman, Annie Wiseburg, and the attempted killing of a liquor store clerk in October that same year. His confession, rich in details about the locations, victims, and methods used, matched what investigators knew but had never been able to connect to a single offender.
Hickson's admissions finally provided the resolution that had eluded Aiken County for more than a decade. They confirmed that Mary Bennett had not been killed by the man who had once stood on death row in her name, but by a serial predator who had terrorized the area in 1946. Hickson was charged with the multiple murders and the attempted murder linked to his confession, and he was ultimately convicted and sentenced to four consecutive life terms for the killings, including the murders of Mary and Edward Bennett. Meanwhile, his detailed admissions cleared any lingering doubt about Harris's role; where the law had already exonerated Harris by overturning the coerced confession, Hickson's words supplied the factual narrative that showed the wrong man had nearly paid with his life for Mary's death.
The story's final chapter played out behind prison walls and on wanted posters rather than in the Bennett grocery. While serving his life sentences at Manning Correctional Institution, Hickson escaped in March 1966, walking away from an outside work detail. A federal warrant followed, and in 1967 he was placed on the FBI Ten Most Wanted Fugitives list. The man who had stolen Mary Bennett's life and helped send an innocent man to death row became one of the country's most sought-after fugitives. His run ended not with an arrest but with a discovery: in late 1967, a migrant farm worker known as Willie Tyler died in Chapel Hill, North Carolina. Months later, authorities identified him as Monroe Hickson through fingerprints, confirming that the killer who had once walked into a small Aiken grocery and destroyed a family had died far from the scene of his crimes.
Mary Bennett's death thus became part of a larger, haunting story—of a small-town family shattered in seconds, a community's fear, a wrongful arrest built on a coerced confession, and a serial killer whose belated confession and eventual status as a most-wanted fugitive forced the record to be corrected. Her case stands at the intersection of personal tragedy and legal history: a reminder of the human cost when violence erupts in an ordinary place, and when the rush to solve such a crime leads investigators to the wrong doorstep.
