The Schizophrenic Girl Who Became Popular After She Stabbed Her Mother To Death

After brutally killing her mother Yun Mi Hoy at their Colorado home in August 2013, Isabella Guzman gained notoriety online for her peculiar demeanor in court.

In their Aurora, Colorado, home in 2013, Yun Mi Hoy was fatally stabbed by Isabella Guzman. Guzman rose to fame online after a TikTok video of her appearing in court went viral seven years later.

Guzman violently killed her mother when she was only 18 years old. Her family was in disbelief. Even as a young girl, she exhibited behavioral problems, yet family members characterized her as “kind” and “good-hearted.”

Guzman pleaded not guilty due to insanity at the time of her arrest. She was diagnosed with schizophrenia by doctors, and a judge mandated that she remain in a mental health facility until she posed no harm to herself or to others.

Guzman requested to be released from the facility after seven years in the hospital, claiming that her schizophrenia was under control. During the same period, TikTok users began sharing footage from her 2013 court appearance, giving her a startling fan base.

Isabella Guzman’s Troubled Childhood

Early on, Isabella Guzman displayed behavioral problems. When she was around seven years old, her mother reportedly moved her to live with her biological father, Robert Guzman, out of fear. Guzman finally returned to living with Hoy, but she struggled throughout her adolescence and dropped out of high school not long after.

Guzman and Yun Mi Hoy’s relationship suddenly deteriorated in August 2013. Guzman allegedly started acting “more aggressive and disrespectful” toward her mother, and on Tuesday, August 27, the two got into a particularly heated dispute that led to Guzman spitting in her mother’s face, according to her stepfather, Ryan Hoy.

The following morning, Hoy reportedly received an email from her daughter that simply said, “You will pay,” according to CBS4 Denver.

Hoy contacted the police out of fear. When they got there that afternoon, they spoke with Guzman and warned her that if she didn’t start respecting her and abiding by her rules, her mother may evict her officially.

Additionally, Hoy called Guzman’s biological father and invited him to meet with her. That evening, Robert Guzman showed up at the residence, according to Huffington Post. We sat down in the backyard and I began to talk to her about the respect that people should have for their parents, he later said.

I felt like I made progress,” he said. However, he would tragically learn just hours later that their chat had accomplished nothing at all.

Yun Mi Hoy’s Brutal Murder by Her Daughter Isabella Guzman

Around 9:30 p.m. on August 28, 2013, Yun Mi Hoy made her way home from work. She informed her husband that she was taking a shower upstairs, but he soon heard a crash and terrifying cries.

Just as Isabella Guzman closed the bathroom door, Ryan Hoy hurried upstairs. Guzman had locked it and was pressing on the opposite side as he attempted to push through. He hurried back downstairs to dial 911 when he noticed blood dripping from underneath the door.

According to Huffington Post, Ryan Hoy heard his wife say, “Jehovah,” before seeing Guzman open the door and leave the house carrying a bloodied knife. Guzman “was just staring straight ahead when she walked past him,” the man said, adding that he “indicated that he never heard Guzman say anything and that she didn’t speak to him as she exited the bathroom.”

When he entered the toilet, he discovered Yun Mi Hoy lying naked on the floor with a baseball bat next to her and numerous stab wounds. She was already dead when he tried to revive her. She had been stabbed at least 79 times in the head, neck, and chest, and investigators later discovered that her throat had been cut.

Isabella Guzman had already left the area by the time the cops arrived

Isabella Guzman had already left the area by the time the cops arrived. The public was warned that Guzman was “armed and dangerous” as they swiftly began a manhunt. The following afternoon, police discovered her in a neighboring parking garage, still wearing her mother’s blood on her pink sports bra and turquoise shorts.

Guzman reportedly had to be dragged out of her cell on the day of her arraignment hearing on September 5, 2013, according to CNN. She then made a number of odd faces at the camera in the courtroom while smirking and pointing at her eyes.

Isabella Guzman entered a plea of not guilty due to insanity. She had schizophrenia and had been having delusions for years, according to testimony from a psychiatrist. She had no idea that she was actually stabbing her mother. Guzman, though, believed that Cecelia’s murder had been committed in an effort to save the planet.

According to George Brauchler, the district attorney for Colorado’s 18th Judicial District, “We punish those who make bad decisions when they knew better and might have done something else. Given the extensive schizophrenia, paranoid delusions, audio hallucinations, and visual hallucinations that she was experiencing in this particular case, I am confident that the woman did not know right from wrong and could not have behaved differently.

The Colorado Mental Health Institute in Pueblo was where Guzman was transferred after the judge accepted her plea of not guilty by reason of insanity and instructed her to remain until she posed no threat to herself or her neighborhood.

Isabella Guzman had no idea that her peculiar court appearance would make her an overnight online sensation.

She Became An Internet Sensation After Appearing in Court

Several TikTok users started sharing footage from Guzman’s 2013 arraignment in 2020. Ava Max’s popular song “Sweet but Psycho” was used in some of them. Others displayed artists making an attempt to mimic Guzman’s peculiar courtroom facial expressions.

Online support for Isabella Guzman grew swiftly. Commenters praised her beauty and implied that the murder of her mother must have been motivated. Nearly two million people watched a video compilation of her court appearance. Even Facebook and Instagram fan accounts were created in Guzman’s honor.

She made funny expressions in court

Guzman was still receiving mental health care there, going through counseling, and looking for the right drugs to treat her schizophrenia. She requested her release from prison in November 2020, arguing that she was no longer a danger to people around her.

“I was not myself when I did that, and I have since been restored to full health,” she told CBS4 Denver at the time. I’m no longer psychologically unwell. I pose no threat to myself or others.

Guzman additionally claimed that her mother had abused her for years. She said, “I was mistreated by my parents for a very long time at home. “My parents are Jehovah’s Witnesses, and I left the faith when I was 14; the abuse at home got worse after I left, though,” the author claims.

Isabella Guzman received authorization to leave the hospital for rehabilitation sessions in June 2021. She also expressed regret about the events of August 28, 2013, saying, “If I could alter anything or if I could take it back, I would,” despite having an allegedly abusive relationship with her mother.

    Making a celebrity out of a very sick girl is wrong. Having lived with a sister who was schizophrenic and tried to kill our mother, and raised in a JW family, I understand the dynamics better than most. Unfortunately, the young people think that the parents did something to make her this way. Schizophrenics have a poor record of taking their meds. Why do you think there are so many among the homeless population? Instead of celebrating her, keep in mind that a man lost his wife and she her mother. But to cut her loose without a lifetime of monitoring doesn’t do either her or the public any good. I honestly wonder why there are not advances in time released medications, similar to birth control and insulin meds that can be implanted. Why pharmaceutical companies don’t create these medications? Time the government took over R&D and the patents.

    People are sick to celebrate her. She told her mom she would pay (premeditated) and then later on killed her brutally and people are making social media pages to honor her? What a fucked up world that we live in. She made cute faces in court and now she is a teenaged dream. This is why the world is going to hell in gasoline soaked drawers! Just because millions of people decide to do something stupid together, that does not make it right. Where is the evidence of abuse? How do we know its true? She is a killer that will walk free or is free and mentally ill. What happens if she does it again to someone else? I guess just give her a pat on the back and ask her to make some more funny faces for the millions of stupid idiots that are her biggest fans.
