Ladies and gentlemen, gather around for a story of true crime that'll have you clutching your pearls and shaking your head in disbelief. It's a story of a serial offender so notorious, they might as well have given him a cape and a villainous moniker. Meet Oscar García Guzmán, the man who has turned the state of Mexico into his personal playground of terror.

In a shocking turn of events, the Attorney's General Office of the State of Mexico (FGJEM) has finally put the shackles on Oscar. Oscar is sentenced to a staggering 55 years in prison for his involvement in the heinous femicide of a young woman only known by her initials, M.C.C., a crime he had committed as a child. But that's just the tip of the iceberg.

The year was 2012, a simpler time, or so it seemed. Oscar, the man with a taste for the macabre, found himself in the company of M.C.C. One can only imagine the sinister events that unfolded that fateful day in a property in El Mirador. With the precision of a skilled executioner, he delivered a cranioencephalic blow that ended her life, just like that. But the horror didn't end there.

Oscar's diabolical genius was on full display when he decided to transport the lifeless body using a “diablito” (a handcart) and abandoned it, wrapped in blankets and tied, in a desolate ravine along the Huixquilucan to Rio Hondo highway. As if this grotesque scene wasn't enough, Oscar made his swift escape from the area, leaving behind a trail of fear and anguish.

Now, you might think that sentencing this malevolent mastermind to 55 years would be the pinnacle of justice. But, oh no! Oscar García Guzmán's criminal resume is so long it could wrap around the Earth a couple of times. With this latest sentence, he's added a whopping 335 years to his prison term. Imagine having to mark each day on the calendar for over three centuries. Can anyone say “career criminal”?

The Prosecutor's Office of the Jurisdictional Body of the State of Mexico deserves a standing ovation for their relentless pursuit of justice. They managed to pin Oscar to not one, not two, but four femicides, a homicide, crimes related to a person's disappearance, and even a rape. And in their pursuit of the truth, they had an unlikely ally, the indomitable activist, Frida Guerrera. With her help, they brought down a monster who terrorized the state.

As if Oscar's crimes weren't gruesome enough, recent developments have only added fuel to the fire. Just a few days ago, the Prosecutor's Office secured another hefty sentence of 62 years and 6 months in prison for the femicide of a 27-year-old woman in Toluca. This is a man who treats prison sentences like they're mere parking tickets!

Before that, in May 2022, Oscar found himself sentenced to another 62 years and 6 months in prison for the femicide of a 25-year-old woman, also in the capital of the state of Mexico. On April 1, 2022, he received yet another sentence, this time for the murder of a man in Xonacatlán, and on March 30 of the previous year, he was sentenced for the femicide of a 23-year-old woman. It's almost as if he's collecting prison sentences like trading cards!

But Oscar's crimes didn't just pop up out of nowhere. In September 2021, he was sentenced to 12 years and 6 months in prison for the rape of a woman in Toluca. And if that wasn't enough, he also had a 17-year and 6-month prison sentence hanging over his head for his participation in crimes related to the disappearance of a young woman in Toluca. The man had his fingers in every sinister pie imaginable.

Oscar's reign of terror finally came to an end in December 2019 when he was arrested on Avenida de los Maestros in Mexico City. It took the combined efforts of the Investigative Agents of the Fiscalía Edomex to put the cuffs on this menace. He was swiftly shuttled off to a Penitentiary and Social Reinsertion Center in the State of Mexico, where he would ultimately face the full force of justice.

And now, dear readers, Oscar García Guzmán's long and chilling saga comes to a close with seven resounding sentences. His crimes will haunt the state of Mexico no more. The Attorney General's Office has clarified it that they stand with the victims and will not tolerate such evil.

As the dust settles on this dark chapter, we should remember the resilience and dedication of the investigators who brought Oscar to justice, and the tireless efforts of activists like Frida Guerrera who championed the cause of the victims. It's a grim reminder of the horrors that can lurk just beneath the surface, but also a testament to the power of justice and the indomitable spirit of those who fight for it.
