Boston's Dark Night: The North End Murders

A young woman stands at the edge of the darkened North End, Boston, clutching the arm of her employer as they head home for the night. It’s March 6, 1873. The city is still blanketed with dirty snow, and horse-drawn carriages clatter up and down the frozen street. A sudden shout pierces the quiet—a warning, maybe a scream. Within minutes, two people will be dead, their bodies battered and their skulls crushed in an attack so violent it stuns even the most hardened residents of the city. The Boston Belfry Murders, as the press will soon call them, have begun.

In 1873, Boston was a city in transformation. The Civil War ended less than a decade earlier. The North End, one of its oldest and most densely packed neighborhoods, was a jumble of brick tenements, narrow alleys, and gas-lit corners. Most residents were recent immigrants—Irish, Italian, Eastern European—crowded in rooms above bakeries and cobblers’ shops. Crime rates ran high, but most violence was domestic or drunken brawls; brutal, random attacks by unknown assailants were almost unheard of.

Mary Keating, age 27, worked as a domestic servant for the Prentiss family, living on the top floor of a three-story house near North Square. Her employer, Martha Prentiss, was a widow in her late 40s, known in the neighborhood for her charity and her thick Boston accent. On the evening of March 6th, Mary and Martha left the house around eight o’clock to visit a cousin recovering from illness several blocks away. Both women wore thick woolen coats and bonnets; Martha carried a small basket of soup.

On their return, the women passed through the shadow of St. Stephen’s Church, its bell tower looming above the square. As they entered the alley behind their home, a man stepped from the darkness. Witnesses later described him as young, with a slouch hat pulled low and a heavy overcoat. He carried a thick oak walking stick.

Without warning, the man swung the stick at Martha’s head with enough force to shatter her skull. Mary tried to scream, but the attacker turned on her, striking her three times across the face and head before she collapsed to the cobblestones. The man rifled through Martha’s basket, taking a purse containing $1.70—a sum worth about $40 today. He then vanished into the darkness.

A teenager named Samuel Byrne, running an errand for his father’s bakery, found the women less than five minutes later. He ran to the nearest police officer, Officer Thomas Sullivan, stationed at the corner of Hanover Street. Sullivan and Byrne raced back to the alley. Martha Prentiss was already dead; Mary Keating was barely conscious, bleeding from a deep wound above her right eye.

The North End was soon in chaos. Word spread quickly—by midnight, hundreds of people crowded the street, some carrying lanterns, others demanding the police catch the murderer before dawn. Over the next few hours, more than a dozen officers searched the neighborhood, questioning anyone lingering near the square.

By morning, reporters from the Boston Globe and the Boston Advertiser swarmed the Prentiss house, scribbling notes about “an outrage more savage than any in recent memory.” Martha’s body was carried upstairs for a rudimentary inquest. Mary, still alive, was taken to Massachusetts General Hospital. Doctors believed she would not survive the day.

The police, led by Captain Ezekiel Blake of the North End precinct, began collecting statements. Samuel Byrne described the scene in the alley. Two other witnesses, Michael O’Shaughnessy and Nora Falzone, had seen a man loitering near the church earlier that evening, matching the attacker’s description. Officers found a bloodied oak walking stick in a trash heap less than a block away.

Detectives canvassed the area, examining footprints in the melting snow. The prints were large, suggesting the attacker wore boots size 11 or 12, uncommon for the area’s working-class men. Blake ordered a search of every nearby boarding house for men matching the description.

By the evening of March 7th, Mary Keating regained consciousness for a brief period. With great effort, she managed to whisper to the attending officer that her assailant was “a stranger—not a neighbor—not a friend.” She died before she could give more detail.

The city offered a $500 reward—equivalent to about $11,000 today—for information leading to the killer’s capture. Police patrols increased across the North End. For the next ten days, residents locked their doors before sundown; some formed neighborhood watches, patrolling the alleys with clubs and lanterns.

On March 12th, a second murder occurred. Patrick Driscoll, a cobbler’s apprentice aged 22, was found dead in an alley off Prince Street, his skull crushed in a manner identical to the earlier attacks. Once again, the killer had used a heavy stick or club. Driscoll’s pockets had been rifled, though only a few coins were missing.

This second murder sent Boston into full-scale panic. Newspaper editorials demanded action. Captain Blake called in detectives from other precincts. Forensic science was primitive in 1873; investigators relied on shoe prints, witness statements, and the pattern of the blows. Several suspects were arrested on suspicion, but none could be linked to the crime.

A break came on March 15th, when police received an anonymous letter. The letter, written in block printing, claimed that “the man who kills in the North End is not from Boston—he comes by the night train from Lowell.” The note included no names or concrete details, but Captain Blake sent officers to all North Station arrivals for the next week, checking bags and questioning anyone who fit the attacker’s description.

The killer struck again on March 19th. Louisa Donnelly, age 31, was found dead behind her boarding house near Fleet Street, her skull fractured by a heavy blow. Witnesses reported seeing a tall man with a limp leaving the scene. For the first time, police believed the killer might have a physical disability.

Captain Blake focused his investigation on itinerant laborers staying in cheap hotels near the wharves. Officers checked dozens of establishments, questioning anyone with a limp or a large build. Among those questioned was John Wilde, a 29-year-old peddler from New Hampshire. Wilde wore heavy boots and walked with a pronounced limp, having suffered a leg injury in a mill accident. He matched the description given by witnesses, but police found no physical evidence linking him to the murders. Wilde was released two days later.

While police investigated, the city’s press published lurid, sometimes sensational accounts. The Boston Globe printed sketches of the “Belfry Killer,” suggesting he hid in church towers and stalked his victims from above. The Boston Advertiser ran editorials blaming the crimes on the “foreign element” of the North End, fueling anti-immigrant sentiment.

On March 23rd, a fourth murder occurred. Sarah Walsh, age 19, was attacked as she left evening prayers at St. Stephen’s. She was struck from behind—her skull split open—but, miraculously, she survived. Her statement to police provided a crucial detail: she described her attacker as having a rough voice, an odor of turpentine, and a patchy beard. Sarah remembered seeing a blue tattoo on the man’s right hand—an anchor, like those worn by sailors.

Police quickly canvassed local shipyards and docks, looking for sailors with an anchor tattoo. On March 24th, they located Thomas Garvey, a 35-year-old Irish sailor recently discharged from a merchant vessel. Garvey had a blue anchor tattoo on his right hand, a rough beard, and a known fondness for cheap whiskey. He was questioned at length but had a solid alibi: he’d spent the night of the most recent attack in a nearby boarding house, witnessed by eight other sailors.

At the same time, police considered another suspect: Charles “Charlie” Borden, a 41-year-old stevedore who worked both on the docks and odd jobs at local churches. Borden was known for his violence—he’d been arrested twice for assault—and his fondness for turpentine, used to clean ship’s decks. When officers searched Borden’s room, they found a blood-stained overcoat and a walking stick under his bed.

Borden was arrested and interrogated by Captain Blake and two detectives. Under questioning, he claimed the blood came from a fistfight at a tavern. The walking stick, he said, was his late father’s and had not left his room in weeks. Police compared the stick to the one found after the first murder; the grain and shape matched closely, but there was no direct evidence linking Borden to the scene. The overcoat was sent for chemical testing, but 19th-century forensics could not differentiate animal from human blood.

Despite the circumstantial evidence, the case against Borden was weak. The district attorney declined to prosecute, citing lack of proof. Borden was released on March 30th after two weeks in jail.

By early April, the murders stopped as suddenly as they began. In total, four people had died: Martha Prentiss, Mary Keating, Patrick Driscoll, and Louisa Donnelly. Two more, including Sarah Walsh, survived brutal attacks. No one was ever convicted.

In the aftermath, Captain Blake continued to pursue leads for months. Police questioned dozens of dockworkers, transients, and laborers, but none could be tied conclusively to the crimes. The city’s Board of Aldermen increased funding for night patrols in the North End, adding 20 new officers to the beat.

The press speculated that the killer had fled Boston, perhaps by ship, or died in an accident. Several newspapers suggested that the murders were the work of a single deranged individual, possibly suffering from “homicidal mania,” a Victorian term for what would now be called serial homicide.

The case revealed major weaknesses in 19th-century urban policing. Officers lacked training in handling violent crime scenes, gathering evidence, or preserving physical clues. Communication between precincts was slow—it sometimes took hours for news of a murder to reach all officers in the city. The reward system, intended to encourage informants, led to dozens of false leads and several innocent men being jailed without cause.

The pattern of the attacks—random, sudden, and extremely violent—was new to Boston. Most murders in the city at this time were crimes of passion or domestic disputes. The “Belfry Killer” targeted strangers, striking without warning and vanishing before anyone could react. This randomness created a climate of fear that lasted well into the summer of 1873.

Local churches reported a drop in evening attendance. Boarding houses required residents to show identification and keep to strict curfews. Some families moved out of the North End entirely, seeking safer neighborhoods in Cambridge or Roxbury.

The press’s coverage of the murders was both sensational and damaging. Many newspapers blamed immigrants, leading to a spike in anti-Irish and anti-Italian sentiment. Several Irish-owned businesses were vandalized in the weeks following the attacks. Police received over 100 anonymous tips blaming the crimes on foreign gangs, though no evidence supported these claims.

The Boston Belfry Murders remain unsolved to this day. Modern historians have reviewed the case and suggest that the killer was likely a transient laborer or sailor, passing through Boston for a short period. The use of a heavy stick or club, the selection of isolated alleys, and the lack of a clear motive beyond robbery point to a perpetrator with both opportunity and familiarity with the North End’s labyrinth of backstreets.

No physical evidence from the case survives. The walking stick and coat, once held as evidence, were long ago lost or discarded. The police reports, written in looping Victorian script, are preserved in the city archives but offer few new clues.

The case led to reforms in Boston’s police force. Over the next decade, the city invested in better lighting for alleys, more foot patrols in crime-prone areas, and the establishment of the detective bureau. The murders also spurred public debate about mental illness and the dangers of urban anonymity—the idea that anyone, not just known criminals, could commit terrible violence and then vanish into the crowd.

The last, and perhaps most chilling, fact: the killer’s identity was never discovered. His motives, precise methods, and fate remain hidden. The city’s first true serial murders set a precedent for urban fear—a story that spread far beyond Boston’s damp, lantern-lit streets.
