A disturbed Florida teen accused of plotting to kill a classmate to bizarrely “resurrect” Sandy Hook monster Adam Lanza penned a sob story to the judge in her case — blaming the internet for making her a “horrible, horrible person.”

Isabelle Valdez, 15, had initially cracked jokes with accused co-conspirator Lois Olivios Lippert, 14, after their arrest, saying they would become famous for their hot mugshots and go on to be a “lesbian couple in jail.”

But Valdez changed her tone this week, sending the judge in her case a three-page handwritten note claiming that being “isolated from people, the internet” since her arrest in January left her “remorseful.”

“I was exposed to the internet at a very young age, and all that was bad stemmed from it,” Valdez told the judge in the letter filed in Seminole County Court.

“The internet made me a horrible, horrible person.”

She also insisted she was “not the same girl I was those three months ago,” when she was accused of plotting to ambush a male classmate in the school bathroom to stab him in the stomach or cut his throat — then leave flowers and smoke a cigarette.

“I’ve been thinking about my life and my choices and I please beg and ask of you to please have some sympathy on me for as I want to change and I’m changing as a person,” Valdez wrote in the letter.

Valdez wrote that she became an active member of the twisted True Crime Community online — which glorifies school shootings like Columbine and the Sandy Hook massacre — in 2022-2023.

She felt “seen” in the group, she wrote, “but in reality it was deteriorating me.”

“I got groomed in this community further into believing that violence was good, the people that were my so-called friends only ever wanted me to harm myself or others,” she wrote.

She also described her struggles with being bullied, and claimed she’s been suicidal since the age of 7.

Valdez and Lippert, from Altamonte Springs, were arrested on Jan. 22  after a tipster told police about their sick plans to murder a classmate at Lake Brantley High School, officials said.

The victim reminded Valdez of Sandy Hook Elementary School shooter Adam Lanza, who murdered 20 children and six adults in 2012 — and she thought killing the boy “would resurrect him from the dead,” according to court documents.

After they were arrested, Valdez and Lippert were caught on camera cracking cringey jokes about the murder plot in the back of a police car. 

Valdez told her best friend she wanted to wear makeup to look attractive in her mugshot, but couldn’t find any that morning, according to court documents.

“Valdez then said ‘At least they will see me in the mugshot some way or another’” — suggesting that they would become famous in the true crime community, according to the report.

They also joked about becoming a “lesbian couple in jail.”

Both teens are charged with attempted first-degree murder.
