In one year, a Florida teenager takes the lives of both parents, according to police.

In Oklahoma, a teenager who killed his father last year and claimed self-defense was not prosecuted. Now, he faces first-degree murder charges in Florida for allegedly stabbing his mother to death.

The 17-year-old has been charged with first-degree murder for killing his 39-year-old mother. Polk County Sheriff Grady Judd stated at a Wednesday press conference that he is urging the state attorney's office to prosecute the teenager as an adult and believes that the teen would reoffend if released.

Judd stated, "When you observe this individual, you perceive a child. However, when I gaze upon him, I see a psychopath with completely erratic behavior. At the age of 17, he has already shot and killed his father and got away with it, and he has also stabbed his mother in the neck so deeply that the knife has gone through her entirely."

"He has killed two people and his parents, and I can confidently say that if he lived with his grandmother and she disobeyed him, she would be the next victim."

On Sunday, the teen reported to 911 dispatchers that his mother had "fallen into a knife" following a "prolonged argument," according to Judd.

Judd stated that the deputies who arrived at The Hamptons, a 55-and-older community in Auburndale, found the teen "calm, cool, and collected" with blood on him.

The 17-year-old reportedly became uncooperative, showed zero remorse, and had no sense of urgency about his gravely wounded mom.

Judd stated, "I know my rights and I want an attorney."

Despite the teen's claims of a prolonged argument with his mother prior to her passing, the house was "tidy and immaculate," Judd stated.

According to police, witnesses reported seeing the teenager and his mother arguing outside their home before the teenager grabbed his mother's hair and dragged her inside, with her repeatedly begging to be released.

The teen's grandmother, who was absent during the confrontation, informed WFLA that the teen had been argumentative with his mother on multiple occasions.

A medical examiner found that the deep knife wound in the neck of the deceased was not accidental.

"On Wednesday, Judd stated that the medical examiner's explanation of her death was not reasonable or plausible, and that it didn't happen that way."

As investigators delved deeper into the case, they discovered that the incident was not an isolated occurrence; the teen's father had also passed away by his own hand last year.

"On Valentine's Day in 2023, in Lincoln County, Oklahoma, Judd stated that his dad threatened him with a knife, and he shot and killed him in self-defense."

Judd stated that Oklahoma authorities dropped charges against the teen less than a month after the shooting due to their inability to disprove his claim of self-defense.

The teen, who was bailed out of jail by his mother for $50,000, was later involuntarily committed to a hospital for mental health reasons within a month of moving into his mother's home in Charlotte County, Florida.

Judd stated that he made a threatening statement around this time, saying, "I'll either kill myself or my mother by shooting or stabbing her."

In November 2023, the teenager pushed his mother to the ground and stomped on her after she took away his video game privileges, according to Judd. Despite claiming self-defense, he was arrested and the argument failed, resulting in his spending time behind bars, the sheriff said.

In February of this year, the teen left his mother's house and went to his grandmother's house in Auburndale after another argument. Both his mother and grandmother contacted the sheriff's office, stating that they felt unsafe around him. As a result, the teen was handed over to family services.

Despite making more threats to kill his mother, the teen was reunited with his family two weeks later, Judd said.

On Sept. 6, the teen had an argument with his mother about home chores, which led him to flee from his mother's house and go to his grandmother's house. The next day, the suspect's mother drove to the grandmother's house, resulting in an altercation that cost her life.

Judd stated that he would provide any information discovered in his investigation that could implicate the teenager in his father's death to the authorities in Oklahoma.

"If Oklahoma had acted, the teen's mother would be alive and well today. However, because she took him in and tried to act like a mother should, she is now dead. Furthermore, everyone who should be special to him in his life is dead when he crosses them," he stated.
