Barbara Graham Executed in America’s Gas Chamber — But Was She Innocent? 

June the 3rd, 1955. San Quentin State Prison, California. A 32-year-old woman is being strapped into a gas chamber chair. Her name is Barbara Graham, and every newspaper in the country knows her by a different name, Bloody Babs. She is only the third woman the state of California has ever executed, but here is what makes this case different from anything you have heard before.

 The only witness who placed her at the murder scene, he walked away without spending a single day in prison. Not one. The police couldn’t find enough evidence to convict her, so they sent an undercover officer to create it. And Barbara Graham, she told anyone who would listen that on the night of the murder she was home with her husband and her newborn son. Someone is lying.

 The question is, who? By the end of this video, you will be asking yourself, did California execute the right person? Welcome back to the channel.

 Her name was Mabel Monahan. She was 64 years old, a widow, living alone in a quiet neighborhood in Burbank, California. By all accounts, Mabel kept to herself. She was not loud, not flashy, not trouble. She was simply a woman living out her later years in the home she knew. She had no criminal record, no dangerous connections, no enemies, but someone had attached her name to a rumor.

 Her former son-in-law was a Las Vegas casino investor, a man with ties to organized crime, and somewhere in the criminal underworld of Los Angeles, a story began to spread that this man had left behind a safe containing $100,000 hidden inside Mabel’s home. Mabel knew nothing about any safe. She was not guarding money.

 She was not connected to any of it. She was just a quiet elderly woman living in a house that someone else had decided was worth breaking into. She did nothing wrong. She just lived in the wrong house. And that decision, made by dangerous men chasing a rumor, would cost Mabel Monahan everything. Now, let’s talk about Barbara Graham.

Because to understand how she ended up in that gas chamber, you have to understand where she started. Barbara was born on June the 26th, 1923, in Oakland, California. Her mother, Hortense Ford, was an unwed teenager. There was no father in the picture, no stability, no plan. When Barbara was roughly 2 years old, her mother was arrested and sent to a reformatory.

Barbara was left behind, alone. What followed was a childhood that moved from foster homes to a convent school to an orphanage. No consistency, no real family, just a little girl being passed from one place to the next. Just after her 14th birthday, she was sent to the California School for Girls in Ventura, a harsh reform institution, the same one her own mother had been locked in years before.

 She was paroled at 16, married almost immediately. Her first son was born in 1940. By the time Barbara reached her mid-20s, she had worked in bars, brothels, and gambling joints across California. She married four times: Harry Cleman, Al Bushnell, Charles Oldman, and finally Henry Graham, a bartender with his own criminal ties.

 She gave birth to three sons and lost custody of at least some of them. Her criminal record by the early 1950s included perjury, prostitution, narcotics possession, and bad checks. Notably, not one violent offense. She even served time at Tehachapi Women’s Prison for for a false alibi to protect someone else. After her release, she connected with Emmett Perkins, a gambling parlor operator linked to Los Angeles mobster Mickey Cohen.

 Historian Kathleen Cairns put it plainly, “I’m not sure she was totally aware of how bad they really were.” What she walked into next and what it would cost her is almost impossible to believe. By early 1953, Barbara Graham was working directly for Emmett Perkins inside his gambling operation. It was there that she moved closer to two men who would change everything, Jack Santo and John True.

Both carried extensive violent criminal records. These were not small-time hustlers. These were dangerous men and dangerous men talk. A rumor had been moving through the criminal network of Los Angeles. Mabel Monahan’s home in Burbank allegedly contained a hidden safe holding $100,000 in cash connected to mob-linked casino money.

 Nobody confirmed it. Nobody verified it. Not one person in that circle could prove the safe even existed. But greed does not wait for proof. Perkins, Santo, and True began discussing the job. According to court records, there is no evidence that Barbara initiated or planned the robbery. Her exact role in those conversations was disputed all the way through her trial.

 Her husband Henry Graham was present in her life at this time, but court records show no evidence he knew anything about what was being planned. Then the group brought in a fifth man, Baxter Shorter. One member of this crew would vanish before the trial ever started. He was never seen again. Five people, one target, a plan built entirely on a rumor.

 Let’s break down who was involved and what each of them brought to the table. Emmett Perkins was the organizer. He ran the gambling operation connected to Mickey Cohen’s Los Angeles crime network. He supplied the muscle and the motivation. Jack Santo was the enforcement, an experienced violent offender who knew exactly what this kind of job could require. John True was a participant.

But True had one quality the others lacked. He knew when to switch sides. He would later trade his testimony for complete immunity. Baxter Shorter was recruited to round out the crew. He would disappear before the trial began. His fate remains unknown to this day. He never testified. And then there was Barbara Graham.

 Per John True’s court testimony, Barbara’s role was to get them through the front door. She would approach Mabel Monahan’s home at 8:15 Parkside Avenue, Burbank, posing as a distressed woman who needed to use the phone. A 64-year-old widow alone at night would open the door for a woman in distress. That was the entry point.

 Once inside, according to True, Barbara was armed with a handgun. The date was set, March the 9th, 1953. No payment structure existed. No contract. This was speculative robbery built on an unverified rumor. If you have not subscribed yet, now is the time. This case only gets more disturbing from here.

 Hit that button and let’s keep going. March the 9th, 1953. Burbank, California. The night that changed everything. By early evening, the group had assembled. The destination was confirmed, 8:15 Parkside Avenue, Mabel Monahan’s home. A quiet street, a defenseless woman, and a crew of five people chasing money that may never have existed. They moved toward the house.

Barbara Graham went to the front door first. Per John True’s court testimony, she knocked. She posed as a woman in distress, a stranger who simply needed to use the phone. Nothing threatening, nothing alarming. Mabel Monahan opened the door. She should not have. The crew forced their way inside.

 What followed, according to True’s testimony, was immediate and violent. Barbara struck Mabel Monahan with the butt of a handgun. The first blow landed on a 64-year-old widow who had done nothing wrong and had no way to defend herself. Then the search began. Perkins, Santo, and True tore through the house, room by room, looking for the safe.

 Looking for the $100,000 that the rumor had promised them. They found nothing. No safe, no cash, no mob money, nothing. The rumor was worthless. The whole plan had been built on air. But rather than walk away, the group made a decision, a brutal one. They were not going to leave a witness. Per True’s testimony, Barbara pulled a pillowcase over Mabel Monahan’s head.

Then Emmett Perkins tied her hands together. Then Jack Santo fastened a length of cloth around her neck. Mabel Monahan was left on the floor of her own home, bound, beaten, unable to breathe. She died of asphyxiation, slowly, alone. The crew left with virtually nothing of value. When Monahan’s body was eventually discovered, the Burbank home told the story clearly.

 Signs of forced entry, visible struggle, and a woman who had been left to die. Mabel Monahan, age 64, was pronounced dead. Cause of death, asphyxiation. Now, here is what you need to hold on to. No murder weapon was ever recovered. No fingerprints linking any suspect to that house were confirmed. The only person who placed Barbara Graham inside that home was John True.

The same man who walked away without facing a single charge. The men who tied her hands and tightened the cloth around her neck, only one of them would ever face a jury. What happened to the others is one of the most infuriating parts of this entire story. After that night, the crew scattered, but not in the way you might expect.

Barbara Graham did not run. She did not flee the state. She went back to her life with Henry Graham, present, visible, and maintaining her daily routine. Nothing in court records documents a dramatic change in her behavior in the weeks that followed March the 9th. John True quietly began putting distance between himself and the others.

 No loud moves, no confrontations, just distance. And Baxter Shorter, the fifth member of the crew, simply vanished. No arrest, no testimony, no explanation. His disappearance was never publicly resolved. Here is something worth noting. This was not a case where someone collected insurance money or walked away with a financial reward.

 The robbery was a complete failure. The group left Mabel Monahan’s home with nothing of value. They got nothing, and they left behind a dead woman. The case against Barbara Graham would not be built on suspicious behavior after the fact. It would be built on one man’s words and a recorded conversation that the police themselves engineered.

 The Los Angeles Police Department and Burbank authorities opened their investigation, and almost immediately, they hit a wall. No murder weapon was recovered. No fingerprints were confirmed at the scene. There was no physical evidence directly linking Barbara Graham, Emmett Perkins, or Jack Santo to Mabel Monahan’s home on Parkside Avenue.

 What investigators had was a dead 64-year-old woman and a rumor about mob money. That was not enough. The press, however, did not wait for evidence. Coverage of Monahan’s death spread quickly across local news. The mob money angle made it impossible to ignore, and Barbara Graham’s name surfaced early. Police connected her to Perkins and the broader criminal circle around Mickey Cohen’s operation.

 Before she was formally charged with anything, her prior record was already part of the public story. Prostitution, perjury, narcotics, bad checks. The court of public opinion had begun its own trial. But inside the investigation, the reality was stark. Without a cooperating witness, this case had very little chance of ever reaching a courtroom.

Then John True made a decision. So did the police. Investigators made a move that decades later legal experts would call deeply troubling. What they did next changed everything. And not necessarily in the way justice intended. Two things happened almost at the same time, and together they sealed the fate of three people.

 First, John True made a deal. He agreed to testify against Barbara Graham, Emmett Perkins, and Jack Santo in exchange for complete immunity from prosecution. Every charge, every consequence, gone. The man who stood inside Mabel Monahan’s home the night she died would not spend a single day behind bars. Without True, prosecutors had almost nothing.

 With him, they had a case. But the police were not done. At the same time, the Los Angeles Police Department sent an undercover officer to contact Barbara Graham directly. The officer posed as a criminal fixer, someone who could provide her with a fake alibi for the night of March the 9th. Barbara engaged in the conversation.

 She believed she was talking to someone who could help her. Every word was secretly recorded. Those recordings were later presented in court as evidence against her. Barbara maintained she was looking for protection, not confessing to anything. But the prosecution told a very different story. Approximately two months after the murder, in May of 1953, Barbara Graham, Emmett Perkins, and Jack Santo were formally arrested on suspicion of murdering Mabel Monahan.

The headlines erupted. Barbara’s appearance, her background, and the details of the crime made her the face of every front page. Baxter Shorter was never arrested. He had vanished. And John True, the man whose words would send three people to death row, walked free. August the 18th, 1953. Los Angeles Superior Court.

 The trial of Barbara Graham, Jack Santo, and Emmett Perkins officially began. All three defendants were tried together. And from the very first day, the odds were not equal. Presiding over the courtroom was Judge Charles Fricke, a man who had already sentenced dozens of defendants to death. This was not unfamiliar territory for him.

 Capital cases were routine. For Barbara’s defense attorney, Jack W. Hardy, it was anything but routine. This was his first capital murder defense. His very first. The prosecution rested its case on two pillars. The first, John True’s test- imony. He told the court that Barbara Graham was inside Mabel Monahan’s home that night, that she struck first, that she was the initial aggressor against a defenseless elderly woman.

 The second, the recorded conversations between Barbara and the undercover police officer. Prosecutors presented them as proof that she had sought a false alibi and made statements that pointed directly to her guilt. Hardy had no physical evidence to counter either. No fingerprints, no weapon, no independent witness.

 And then there was Barbara herself. She walked into that courtroom in tight clothing and high heels. She sat at the defense table and smoked. She radiated anger. She showed no vulnerability, no softness, no performance of remorse. Historian Kathleen Cairns wrote it plainly. She was always her own worst enemy. The jury saw a woman who refused to appear helpless.

 Combined with True’s testimony and the recordings, it was enough. In September of 1953, the jury returned guilty verdicts against all three defendants, first-degree murder. Under California law at the time, that verdict carried one automatic outcome, death. Appeals followed. Barbara never stopped claiming her innocence.

 Years later, historian Gordon Bakken stated clearly, “By today’s standards, with a decent attorney, Barbara Graham would not have been convicted.” But John True walked free. Baxter Shorter was never found, and three people were handed death sentences. That disparity never sat right, and it still doesn’t. Barbara Graham spent roughly two years on death row at San Quentin State Prison, and in that time, something unexpected happened.

 Journalists began visiting her, interviewing her, listening to her. And one by one, several of them left those conversations believing, at minimum, that the trial had been deeply flawed. One reporter stood out above the rest, Edward S. Montgomery of the San Francisco Examiner, a man known for siding with the prosecution, a man who had covered countless criminal cases without question.

 Something about Barbara Graham’s case stopped him cold. He could not fully explain it himself, but he became one of her most vocal supporters. Montgomery eventually brought her story to Hollywood producer Walter Wanger, a man known for making films powerful institutions. But none of it was enough to stop what was coming. Every appeal was filed.

 Every appeal was denied. The governor’s request for clemency was also denied. Emmett Perkins and Jack Santo exhausted their appeals as well. June the 3rd, 1955, San Quentin State Prison. Barbara Graham was 32 years old. She was escorted to the gas chamber. Reports from the time describe her as composed, still maintaining her innocence until the very end.

 She was strapped into the chamber chair, cyanide pellets dropped into acid. She died of asphyxiation, the same cause of death as Mabel Monahan. Barbara Graham was pronounced dead, the third woman ever executed by the state of California. Perkins and Santo were executed around the same period. Their deaths received a fraction of the press attention hers did.

 John True, the man whose testimony put all three of them there, lived the rest of his life as a free man. Baxter Shorter was never located, never charged, and never tried. In 1958, actress Susan Hayward portrayed Barbara Graham in I Want to Live, winning the Academy Award for Best Actress, and turning this case into a national conversation about capital punishment that continues to this day.

Here is what we are left with. Mabel Monahan had no widely documented surviving close family. Her grief belongs to a public record that barely acknowledged her beyond the crime itself. The safe, the $100,000 that started all of this, was never found. It may never have existed at all. Three people died in a gas chamber over a rumor.

 The one man who put them there walked away without consequence, and Barbara Graham, a woman who spent her entire life being failed by every institution that was supposed to protect her, died inside one. Whether she held that pillow case or not, the system that processed her was not built for nuance. What moment in this case hit you the hardest? Drop it in the comments.
