It’s the kind of story that sounds too dark, too surreal — even for a crime movie. But in the small Argentine town of Pico Truncado, truth proved far stranger — and more disturbing — than fiction. What began as a brutal murder in 2010 would soon spiral into one of the most shocking love stories the world has ever heard: a woman marrying the man convicted of killing her identical twin sister.
On July 16, 2010, 19-year-old model Johanna Casus was found dead — shot in cold blood. The town was horrified. Her ex-boyfriend, Victor Singalani, was swiftly arrested, and within months, he was convicted and sentenced to 13 years in prison. Justice, it seemed, had been served.
But that illusion shattered three years later.
Because Johanna’s twin, Edith Casus, suddenly announced she was engaged to Victor — the man accused of murdering her mirror image.
The announcement sent shockwaves through Argentina. The Casus family was devastated, pleading with Edith to reconsider. Her mother, unable to comprehend the decision, even took legal action to stop the marriage. But Edith, calm and determined, passed a psychological evaluation that declared her “mentally fit to marry.”
And so, on Valentine’s Day, 2013, while the rest of the world celebrated love, Edith Casus walked into a prison and said “I do” to the man the courts said had destroyed her family.
💔 “She married her sister’s killer,” screamed the local headlines. Crowds gathered outside the prison, chanting in protest. Some called Edith “delusional.” Others whispered that she was haunted by her twin’s ghost — trapped in a web of trauma and obsession.
But then, the story took another shocking twist.
As appeals and investigations unfolded, prosecutors began to question Victor’s guilt. New evidence suggested that Johanna’s then-boyfriend, Marcos Diaz, might have been the real killer — and that Victor’s conviction had been built on shaky ground. Rumors spread that Victor had taken the fall out of fear, manipulation, or misplaced loyalty.
In December 2013, Victor Singalani was released, his conviction overturned due to “insufficient evidence.” The justice system had flipped, leaving everyone in disbelief. Was he innocent all along? Or had a killer just walked free — now legally married to his victim’s twin?
For years, Edith stood by him. They lived quietly, away from the cameras, as journalists and true-crime enthusiasts dissected their every move. But by 2021, the impossible marriage had finally crumbled. The couple divorced, and Edith, now remarried and a mother, has refused to speak publicly about that haunting chapter of her life.
What drove her — love, trauma, guilt, or denial — remains a chilling mystery. Some psychologists believe Edith’s actions were a subconscious attempt to “save” her sister by merging with the man who took her away. Others see it as a desperate act of rebellion — a woman trying to reclaim control of her life after tragedy.
Whatever the truth, the Casus case remains one of the most disturbing intersections of crime and emotion in modern history.
Two sisters.
One murder.
One marriage that defied logic, law, and morality.
And a lingering question that refuses to fade:
Did Edith Casus marry a monster… or the only man who knew the truth?
🕯️ “Twisted Vows” isn’t just a story of love and death — it’s a haunting reminder that sometimes, the heart doesn’t follow reason… it follows obsession.
