Mile-High Matricide

Is this the face of a killer? (Isabella Guzman/Facebook)

“You will pay.”

That was the message sent by 18-year-old Isabella Guzman to her mother—47-year-old Yun-Mi Hoy—through Facebook last Wednesday in Centennial, Colorado. And this just one day after an argument with her mom ended with Isabella spitting in her face and storming out of the house.

No one knew the cause of Isabella’s rebellious behavior—many credited it to the growing pains all teenagers experience—but Hoy was worried. She called the police and told them her daughter “had threatened to harm her,” so officers spoke with Isabella and told her Hoy could throw her out if her bad behavior continued.

Though this seemed to help, Hoy took no chances and reached out to Robert Guzman—her ex-husband and Isabella’s father—who immediately came to speak with his daughter.

“We sat down in the backyard… and I started to talk to her about the respect that people should have for their parents,” Guzman said later. “I thought that I made progress, but obviously it didn’t do nothing.”

What it did—judging from what happened next—was set Isabella off. Apparently all of the lecturing from parents and police lit some kind of fuse deep within the rebellious teen. And when she exploded, there was only one person in her path: her mother.

Ryan Hoy, Isabella’s stepfather, was downstairs Wednesday evening, enjoying some dinner while his wife prepared for a shower upstairs.

Suddenly, he heard some strange thumping sounds coming from above him, followed by the faint sound of his wife calling his name.

Ryan rushed upstairs and could hear the shower running, but when he tried to open the bathroom door, he discovered it was blocked. He tried to nudge it open, but felt something—or someone—pushing back against him. Just before the door closed and locked, he caught a glimpse of the person responsible.

It was Isabella.

Blood started to pool under the bathroom door, so Ryan scrambled for his cell phone and dialed 911. After telling the operator that his wife was being attacked, he rushed back upstairs and heard his wife whisper “Jehovah” just as the bathroom door opened.

Pretty gruesome: Police arrived and found Mrs Hoy already dead, having suffered 78 stab wounds to the neck and face

Out walked Isabella, covered in blood and with the knife still in hand, arm resting at her side. In complete silence and with a blank stare on her face, the young killer walked past her stepfather, down the stairs and out of the house.

Ryan immediately rushed to his wife and followed the dispatcher’s CPR instructions, but it was too late. Her throat had been slashed and she simply lost too much blood.

An autopsy would later reveal that Hoy had been stabbed 79 times in the face and neck… by her own daughter, no less.

Late Thursday morning, someone noticed a body in a car parked in a garage on South Parker Road. Police investigated and discovered a number of items they believed to be connected to the homicide. A K-9 team was called in and a short time later, Isabella walked out of the garage and right into the hands of the authorities.

She is currently being held in Arapahoe County Jail.

No one knows what drove Isabella Guzman to brutally murder her mother—not even the close family members who knew her best. She had been sent to live with her father for a time at age seven—mostly to give her mom a break from the constant arguing—but Isabella eventually returned.

And what daughter hasn’t argued with her mother, especially during the turbulence of her teenage years?

Of course, rebelling against a parent and hacking them to death in the family bathroom are two very different things. Maybe psychologists and psychiatrists can determine why Isabella chose such a drastic response—a response that effectively ended two lives. And maybe then we can prevent a senseless tragedy like this from ever happening again.

    If I were Isabella’s mom I would put her in the pychietric hospital to try to help her fix her behavior and start medications to control her outbursts and family counseling as well
