Barbara Graham Executed in America’s Gas Chamber — Before She Died: “They’re So Sure They’re Right”

In 1958, Hollywood turned her story into a major motion picture. Susan Hayward won the Academy Award for Best Actress for playing her, and the movie suggested she was completely innocent.

In 2024, former prosecutor Marcia Clark published a book concluding that this woman never received a fair trial and likely never physically harmed anyone the night she was convicted of murder.

The woman they were talking about had been dead for nearly seventy years, buried at Mount Olivet Cemetery in San Rafael, California. She was executed by the state before anyone asked the questions that needed asking.

Her name was Barbara Graham. She walked into San Quentin State Prison on the morning of June 3rd, 1955, wearing a neat beige suit.

Her hair was carefully styled and her face was calm. She was thirty-one years old. The room she was led into smelled strongly of industrial antiseptic, its walls painted a dull green.

At the center sat a single steel chair bolted directly into the floor. She asked for a blindfold, refusing to look at the crowd of people gathered to watch her die.

That same morning, she had been scheduled to die three separate times. Three delays occurred, and three times she prepared herself for the end.

A reporter who covered the execution said he had never seen anything like it in his entire career. Her composure remained striking until the very end.

Before we talk about the crime itself, we need to talk about the woman it was committed against. Her name was Mabel Monahan, though some court records spell it Monahan.

She was sixty-four years old and had lived a full, memorable life long before strangers came to her door. Mabel had once been a vaudeville performer on the Keith-Albee Circuit.

That network was one of the most prestigious entertainment circuits in America at the time. Night after night, city after city, she performed on stage for enthusiastic crowds who gave her standing ovations.

She was a woman of talent, energy, and grace. But by 1953, those glittering stage days were long behind her, replaced by a much quieter existence.

Mabel had traded the spotlight for a quiet, solitary life in a modest home in Burbank, California. There were no more crowds or curtain calls, just a peaceful routine in a neighborhood where nothing dramatic was supposed to happen.

The house she lived in had belonged to her daughter, Iris. Iris had received the property in a divorce settlement from her ex-husband, Luther Scherer.

Scherer was a multi-millionaire who owned gambling clubs in Palm Springs and held lucrative casino investments in Las Vegas. Iris later remarried and moved to New York, leaving her mother behind in the Burbank residence.

Scherer and Mabel remained close friends after the divorce. That innocent friendship sparked dangerous rumors in the local criminal underworld.

Word spread through bars and underground networks that Scherer, trusting no one more than Mabel, had hidden a hundred thousand dollars in cash inside a safe in her home.

There was no safe, and there was no hundred thousand dollars. The only valuables in that house were fifteen thousand dollars worth of jewelry sitting quietly in a purse inside a closet, which her killers never found.

Mabel Monahan did not die because of anything she had done. She died because of a baseless rumor, simply because she opened her front door to a stranger.

To understand Barbara Graham, you cannot start with the crime itself. You have to start much earlier, because long before she became a national headline, she was a child failed by the system.

She was born Barbara Elaine Ford on June 26th, 1923, in Oakland, California. Her mother, Hortense Ford, was a teenage unwed woman of Portuguese Azorean descent who supported herself through prostitution.

Barbara’s father was never in the picture. When Barbara was just two years old, Hortense was arrested and sent to the Ventura State School for Girls, a juvenile reformatory.

Barbara was placed in foster care, where she later alleged that she was beaten and mistreated in the homes where she was assigned.

When Hortense was eventually released at age twenty-one, she refused to allow Barbara to live with her. Barbara was raised instead by strangers and extended family members who constantly came and went.

Despite the instability, Barbara was remarkably intelligent. Court records and later prison testing would confirm she had an IQ of 114, though her formal education was broken and limited.

By the time she was fourteen years old, Barbara had been arrested for vagrancy and sentenced to the Ventura State School for Girls—the very same reform school her mother had attended years before.

Released in 1939, Barbara tried to build a normal life. She married a United States Coast Guardsman named Harry Keelhammer in 1940, enrolled in a business college, and gave birth to two sons.

By 1942, the marriage had completely collapsed. Harry was awarded sole custody of both boys, and Barbara lost her children entirely.

She married twice more after that, but both marriages failed quickly. During World War II, she entered sex work, becoming what was known in naval ports as a “seagull.”

These were women who followed the naval fleets between bases in cities like Long Beach, San Diego, and San Pedro. She was arrested on vice charges in several of those coastal cities.

At twenty-two, she worked in San Francisco for a well-known brothel madam named Sally Stanford. From there, Barbara became deeply embedded in gambling and narcotics circles, surrounding herself with ex-convicts and career criminals.

Her first serious conviction came when she provided a false alibi for two petty criminals. She was convicted of perjury and served five years at the California Institution for Women in Tehachapi.

After her release, she drifted through Reno and Tonopah in Nevada, working briefly as a hospital worker and a waitress before boarding a bus back to Los Angeles.

She rented a room on Hollywood Boulevard and returned to the only life she had ever known. In 1953, she married Henry Graham, a bartender and low-level criminal with a severe drug addiction.

Together, they had a son named Tommy. He was Barbara’s third child and the only one she ever raised with a partner at her side.

It was Henry Graham who introduced her to the men who would ultimately bring her world to an abrupt and fatal end.

Henry Graham’s drug addiction worsened rapidly throughout 1952 and into 1953. As his habit escalated, the people surrounding him became increasingly dangerous.

Through Henry, Barbara was introduced to two men whose names would follow her for the rest of her life. The first was Jack Santo, and the second was Emmett Perkins, known in criminal circles as “The Weasel.”

Both men carried extensive criminal records. Court records would later link Santo and Perkins to six separate murder cases between them.

These were not small-time street criminals; they were hardened, calculating, and violent men. Barbara soon began an affair with Perkins, a relationship that pulled her deeper into his dangerous world than Henry ever had.

It was Perkins who first mentioned Mabel Monahan to the group. He told Barbara about an elderly widow living alone in Burbank, California, and repeated the rumor circulating through Los Angeles bars.

He claimed that a hundred thousand dollars in cash was sitting in a safe inside that woman’s home, waiting for anyone brave enough to take it.

Barbara’s own criminal record up to that point was strictly nonviolent, consisting of prostitution charges, bad checks, and perjury. She had never been connected to anything that ended in bloodshed.

What Perkins was proposing was a completely different category of crime. Moving in and out of this circle around the same time were two other men: Baxter Shorter and John True.

Their roles in what was coming would prove to be decisive. The Los Angeles criminal underworld of 1953 was closely connected to casino money, mob-linked figures, and the network surrounding notorious gangster Mickey Cohen.

This was the dangerous world Barbara Graham now inhabited. On the evening of March 8th, 1953, the group sat down together for dinner in the San Fernando Valley.

That dinner was not a social occasion; it was the night the plan became real. Barbara Graham was about to walk into something she may not have fully understood.

The man who recruited her would later make sure she paid the ultimate price while he attempted to secure his own survival.

By the time that dinner ended on March 8th, 1953, every person at that table had a designated role to play. Emmett Perkins was the one who had brought the group together.

He was the source of the Monahan tip and the driving force behind the plan. He was Barbara’s lover and the most dangerous man in the room.

Jack Santo was Perkins’s partner—equally hardened and equally willing to use violence. He asked few questions and raised no objections to the scheme.

John True was a more peripheral figure brought in to participate rather than lead, but his presence alone was enough to seal his fate and eventually Barbara’s.

Baxter Shorter was recruited specifically as the safe cracker. His presence confirmed what everyone in the group believed: that there was an actual safe inside Mabel Monahan’s home waiting to be opened.

And then there was Barbara Graham. According to Shorter’s later confession and the testimony John True would give in court, Barbara’s role was singular.

She was the lure. The plan required someone who could knock on an elderly woman’s door late at night without raising alarm.

Barbara’s appearance as an attractive, non-threatening young woman was the key that would open Mabel Monahan’s front door.

Court records indicate that Shorter initially objected to including Barbara. He reportedly referred to her as a “dame” and did not want her involved in the operation.

Perkins overruled him without hesitation, arguing that without Barbara at that door, Monahan would never open it.

A witness named William Upshaw would later testify before a grand jury that he had been in the car with the group the night before the murder.

He stated they watched Monahan’s home and went over the plan, but he chose not to participate out of fear of retaliation from Luther Scherer.

The plan itself was straightforward. Barbara would knock and tell Monahan her car had broken down, asking to use the telephone.

Once Monahan opened the door, the rest of the group would push in behind her. No money changed hands that night; the robbery was expected to pay for itself based entirely on an untrue rumor.

The dinner in the San Fernando Valley concluded and the plan was set. All that remained was to carry it out.

Mabel Monahan spent that evening the way she spent most evenings: alone and quiet inside her Burbank home in a neighborhood where nothing alarming was supposed to happen.

She had no reason to expect trouble or fear the dark. The group moved toward Burbank, making their final approach in the early evening hours.

They were in no hurry, fully believing that what was waiting inside that house was worth a fortune.

At approximately nine o’clock that evening, Barbara Graham walked up to Mabel Monahan’s front door alone and knocked.

Monahan answered, and Barbara told her the same story they had rehearsed the night before—that her car had broken down and she needed to use the phone.

It was a simple, believable request that any neighbor might make. Mabel Monahan opened the door, marking the last moment of safety she would ever experience.

Perkins, Santo, and True pushed inside immediately behind Barbara, while Shorter followed shortly after. Five people now stood inside a sixty-four-year-old woman’s home.

What happened next is where the various accounts of the crime begin to split dramatically. John True testified in court that Barbara handed a pistol to Perkins and said, “Knock her out.”

He further testified that Barbara then began to beat Monahan herself viciously and without hesitation.

Baxter Shorter’s confession told a very different story. When he entered the house, Monahan was already bleeding and her mouth was gagged.

Shorter said he did not see Barbara deliver any blows, naming Perkins as the sole primary aggressor.

In 2024, former prosecutor Marcia Clark reviewed the original court transcripts and discovered something critical that had been buried for decades.

The statement John True gave to police before the trial directly conflicted with the testimony he delivered on the stand, specifically regarding who physically attacked Mabel Monahan first.

That original statement was never provided to the defense team, and the jury never saw it.

While Monahan lay bleeding, the group tore through her home, searching every room, drawer, and wall for a safe that did not exist.

They found nothing—no safe and no cash. Fifteen thousand dollars worth of jewelry sat completely untouched in a purse inside a closet, which they never discovered.

Court records established that Mabel Monahan was beaten with a pistol and strangled with a cloth ligature placed tightly around her neck.

She was gagged so severely that she could barely breathe. Shorter’s confession states that he noticed Monahan struggling and urged True to remove the gag, though True’s testimony omitted this detail.

The group left the house believing she was already dead or would be shortly, with Santo reportedly telling the others she was gone.

What happened after they left is one of the most haunting details of the entire case.

Shorter, according to his confession, felt a mix of guilt and fear. He stopped at a payphone to call for help, giving the operator an address—but it was the wrong address.

Mabel Monahan lay bound and dying on the floor of her ransacked home while no help arrived.

Her gardener found her two days later, on March 11th, 1953. The official cause of death was determined to be asphyxiation.

Mabel Monahan might have survived if that telephone operator had been given the correct digits. Her daughter, Iris, called from New York after being notified and offered a five-thousand-dollar reward for information leading to the arrest of her mother’s killers.

The investigation was officially open, and the clock was running for every person who had entered that house.

When the group left Mabel Monahan’s home that night, they left with nothing—no cash, no jewelry, and no safe.

The robbery they had planned for weeks had produced nothing at all. They dispersed quietly into the night and returned to their separate lives as though nothing had occurred.

Barbara returned to her rented room in Hollywood. Her husband, Henry Graham, had no full knowledge of what had taken place that evening.

Meanwhile, in that quiet house on a quiet street in Burbank, Mabel Monahan lay bound on the floor for two full days before being discovered.

On March 11th, 1953, her gardener arrived and immediately alerted the authorities. The Burbank residence was sealed off as a active crime scene.

Iris cooperated fully with investigators from New York, while Luther Scherer also provided complete cooperation to the police.

Court records show Scherer had no prior knowledge of the robbery plot; the rumor about his money had spread entirely without his involvement.

Local newspapers ran prominent stories, but with no immediate suspects or clear physical evidence, it was initially treated as a random home invasion.

In the criminal underworld, however, people were already talking. Baxter Shorter in particular was not handling what he had witnessed well.

He was shaken, deeply troubled, and unable to stay quiet for long. Mabel Monahan had left the stage decades earlier looking for peace, only to lose her life to a baseless rumor.

Detectives had a crime scene and a body, but they lacked a clear path to the perpetrators. On March 26th, 1953, seventeen days after the murder, police finally moved.

They arrested and questioned five men with known connections to Mabel Monahan through Luther Scherer, including three associates of gangster Mickey Cohen.

Baxter Shorter was among those detained. All five men knew Scherer through his casino networks, but knowing someone was not proof of murder.

There was not enough physical evidence to hold any of them, and all five were released. The investigation hit a solid wall.

In 1953, detectives had none of the forensic tools that exist today—no DNA testing, no digital footprints, and no widespread surveillance footage.

This case was going to stand or fall entirely on what people were willing to say out loud under oath in a courtroom.

Barbara Graham had no alibi for the night of March 9th, with no witnesses, receipts, or phone records to place her anywhere else.

Then Baxter Shorter made a fateful decision out of sheer terror of the gas chamber.

He approached the police and offered to turn state’s evidence, giving detectives a detailed account naming Barbara Graham, Emmett Perkins, Jack Santo, and John True.

It should have been the break that solved the case, but his confidential statement was leaked almost immediately to the underworld.

Shortly after Shorter was released from police custody, he was kidnapped. He was never seen alive again, and his body was never recovered.

Court records indicate he was murdered by Perkins and Santo—a key witness eliminated before he could ever take the stand.

The one man who knew exactly what happened inside that house and was willing to speak was now gone.

With Baxter Shorter dead, investigators had to find another way to build their case. A convicted felon named William Upshaw came forward voluntarily.

He testified before a grand jury that he had been in the car with the suspects the night before the murder, watching Monahan’s home and going over the robbery plan.

His testimony placed Barbara at the planning stage, which was damaging, but still not enough on its own to secure a murder conviction.

The prosecution needed someone who had been inside the house that night. John True was facing severe criminal exposure for his presence at the crime scene.

Prosecutors offered him an extraordinary way out: in exchange for his full cooperation and testimony against Barbara, Perkins, and Santo, True was granted complete immunity.

He would never spend a single day in prison for his role in the death of Mabel Monahan.

In court, True testified that Barbara handed a pistol to Perkins, instructed him to knock Monahan out, and then beat the victim herself.

His account placed Barbara as the most physically aggressive person in that house. What the jury did not know was that True’s original statement to police told a very different story.

That original statement was later discovered in the archived files of film producer Walter Wanger and reviewed by Marcia Clark in 2024.

Clark concluded that the original statement directly contradicted True’s trial testimony on key points and was deliberately withheld from the defense.

Under the legal standards of the era, that statement should have been disclosed immediately. While this was unfolding, Barbara sat in jail with no alibi.

A fellow inmate named Donna Prow befriended her in what sources describe as a jailhouse romance, eventually offering her a deal.

For twenty-five thousand dollars, Prow claimed a friend could provide Barbara with a fabricated alibi for the night of the murder. Barbara, desperate, accepted the offer.

The friend was actually Sam Sirriani, an undercover police officer. Sirriani met with Barbara, guided the conversation, and pushed her to confirm details about the night of the crime.

Every word of that meeting was secretly recorded by law enforcement.

When Barbara was later asked at trial why she had gone along with the scheme, she uttered her famous line: “Oh, have you ever been desperate? Do you know what it means not to know what to do?”

Donna Prow vanished before the defense could locate her to testify. Marcia Clark’s research suggests Prow was deliberately kept out of reach by authorities.

At trial, Sirriani testified about the meeting, and the secret recording was played directly for the jury.

Combined with her prior perjury conviction, the recording destroyed whatever legal credibility Barbara had left.

She had not confessed to committing the murder, but she had effectively confirmed her presence at the scene, which was enough for the prosecution.

The murder trial of Barbara Graham, Jack Santo, and Emmett Perkins opened on August 18th, 1953.

The prosecution was led by District Attorney J. Miller Leavy, an aggressive prosecutor who had handled some of California’s highest-profile cases.

Across the aisle sat court-appointed defense attorneys who lacked investigators, independent funding, and the ability to locate critical witnesses.

The structural disadvantage for the defense was built in from the very first day of the proceedings.

Before the jury heard a single word of testimony, the press had already decided who Barbara Graham was.

She was thirty years old, red-haired, and attractive, with a past in sex work and a prior conviction for perjury. That was all the headlines needed.

Reporters dubbed her “Bloody Babs,” describing her as a “gun moll” and a cold-blooded “femme fatale” who killed for pleasure.

The media coverage was relentless and almost entirely focused on her rather than Santo or Perkins.

At trial, John True took the stand and detailed how Barbara supposedly handed over the pistol and beat Mabel Monahan herself.

The jury had no way of knowing his initial police statement had named someone else as the primary attacker.

Sam Sirriani testified about the fake alibi meeting, and the audio recording was played in open court.

Her detractors heard a clear admission of guilt, while her supporters heard a terrified woman who saw no other way out.

The jury deliberated for only a few hours before returning a verdict: guilty of first-degree murder for all three defendants.

Because the jury did not recommend life imprisonment, the judge was required by law to impose the death penalty on all three.

John True collected his complete immunity and walked out of the courtroom a free man, never charged with any crime related to Monahan’s death.

Barbara’s legal appeals were filed from the California Institution for Women in Chino, but every higher court affirmed the conviction.

Barbara Graham spent twenty-six months on death row. What happened to her during that time surprised nearly everyone who followed the case.

Prison records and contemporary journalism document a woman who spent her final months reading Socrates and complex philosophical texts.

She listened to classical music and wrote extensive letters to journalists describing her life, her regrets, and her firm insistence that she had never beaten Mabel Monahan.

She wrote passionately about poetry, stating in one letter: “I have always been a pushover for poetry. Oscar Wilde, Walt Whitman, some Robert Bridges verse seems to say something to me that nothing else can.”

The woman who had arrived at her arrest with heavy makeup and a hardened demeanor had been replaced by someone quiet, composed, and refined.

One reporter who observed her in her final weeks described her as looking like a respectable suburban housewife.

She maintained her innocence until the very end, displaying what observers described as genuine inner conviction rather than mere legal posturing.

On June 2nd, 1955, Barbara was transferred to San Quentin State Prison, home of California’s gas chamber, to spend her final night in the death house.

On the morning of June 3rd, she ordered a hot fudge sundae for breakfast, prayed with a chaplain, and waited for the end.

At ten o’clock in the morning, the execution was scheduled to begin, but Governor Goodwin Knight issued a last-minute stay due to a new legal filing.

The execution was pushed to 10:45 AM, but at 10:43 AM, another petition arrived, delaying it further to 11:30 AM.

A remote stethoscope had already been taped over Barbara’s heart when the second stay was announced, causing her to break down in distress.

She wept and asked her guards, “Why do they torture me? I was ready at ten o’clock.”

At 11:12 AM, the final phone call came from the governor’s office confirming that all final appeals had been officially rejected.

At 11:28 AM, Barbara Graham was finally led into the green gas chamber. She requested a blindfold so she would not have to look at the witnesses.

Barbara Graham’s last words were: “Good people are always so sure they’re right.”

As she was being strapped into the steel chair, an officer advised her that taking a deep breath after the cyanide pellets dropped would make her death faster.

She looked up at the officer and replied, “How the hell would you know?”

At 11:34 AM, the cyanide pellets dropped into the acid bath beneath her chair, and she initially held her breath.

One witness noted that she tilted her head back as if she were praying in her final moments.

At 11:37 AM, she involuntarily inhaled the fumes and was pronounced dead within minutes at the age of thirty-one.

Later that same day, Jack Santo and Emmett Perkins were executed in the exact same steel chair.

John True, whose testimony had secured Barbara’s death sentence, was never charged and lived out the rest of his life as a free man.

Barbara Graham was laid to rest at Mount Olivet Cemetery in San Rafael, California.

In 1958, Hollywood released the acclaimed film I Want to Live!, which reignited a massive national debate over capital punishment.

In 2024, Marcia Clark published Trial by Ambush, offering modern legal analysis that concluded Barbara Graham never received a fair trial under the law.

The case remains one of the most haunting and controversial executions in American history.
