An 18-year-old transgender-identifying female from Indiana has agreed to plead guilty to charges related to a planned mass shooting targeting her former high school, according to prosecutors.

Authorities say the teenager, identified as Trinity “Jamie” Shockley, built a shrine in her bedroom honoring Parkland school shooter Nikolas Cruz.

The Morgan County Prosecutor’s Office confirmed that Shockley will plead guilty to conspiracy to commit murder. The plea agreement, filed on October 24, calls for a prison sentence of up to 12 and a half years, followed by five years of probation.

Investigators said Shockley had been plotting to carry out a mass shooting on Valentine’s Day, coinciding with the anniversary of the 2018 Parkland, Florida, high school massacre that killed 17 people.

Police said the suspect was “in love” with Cruz and had spent months researching mass shootings and communicating admiration for previous attackers.

Authorities began investigating in February after receiving a tip that Shockley had access to an AR-15-style rifle, had purchased a bulletproof vest, and had expressed an obsession with mass shooters.

Officers from the Morgan County Sheriff’s Office executed a search warrant at the teen’s home, where they discovered detailed plans for an attack and a bedroom shrine dedicated to Cruz and other perpetrators of school shootings.

Investigators also found writings and digital files outlining plans for a Valentine’s Day assault on Shockley’s former school. Law enforcement officials said the evidence included online discussions, maps, and timelines suggesting the suspect intended to mark the Parkland anniversary with a copycat attack.

Following the arrest, Shockley was charged with conspiracy to commit murder, intimidation, and unlawful possession of a firearm.

Under the terms of the plea deal, Shockley will face strict post-release conditions, including a permanent ban on firearm ownership and a requirement to abstain from any online searches or research related to school shooters.

The agreement also mandates ongoing internet monitoring through accountability software.

In addition, Shockley must undergo mental health counseling and pay for all associated treatment costs. The court has scheduled the formal plea hearing for November 24.

Morgan County prosecutors said the plea agreement reflects the seriousness of the charges while ensuring the defendant will remain under supervision and treatment after release. Authorities credited the initial tipster for helping prevent what they described as a potentially catastrophic school shooting.

Police reports indicate that Shockley’s case drew comparisons to several other instances in which young individuals fixated on previous mass shooters.

In this case, investigators found what they described as “disturbing personal writings” and multiple online communications that celebrated Cruz and other attackers.

Officials said the investigation remains ongoing as law enforcement reviews Shockley’s online activity to determine whether anyone else was aware of or involved in the planning.

The Morgan County Sheriff’s Office emphasized that the case underscores the importance of public vigilance and early reporting of threats. “Tips from the public are often the first line of defense in stopping tragedies like this before they occur,” a spokesperson said in a statement.

Shockley remains in custody pending the formal plea hearing, where the court will determine final sentencing and probationary terms.
