Trans Teen Admits to Plotting Valentine’s Day Mass Shooting at Indiana High School

An 18-year-old transgender student from Indiana has admitted to plotting a Valentine’s Day massacre at her high school, authorities say.

Trinity Shockley, who also went by the name Jamie and identified as male, is expected to plead guilty to felony conspiracy to commit murder as part of a deal with prosecutors, according to the Morgan County Prosecutor’s Office. Under the agreement, Shockley will face a maximum of 12.5 years in prison followed by five years of probation.

A Deadly Plot Inspired by Parkland

Police arrested Shockley in February after receiving a tip that she had access to an AR-15 rifle, had purchased a bulletproof vest, and was “obsessed with mass shootings.” A search of her home uncovered what authorities described as a “shrine” to Parkland school shooter Nikolas Cruz, as well as writings glorifying other mass murderers.

Investigators also found detailed plans outlining a mass shooting at Mooresville High School, which Shockley allegedly intended to carry out on February 14 — the anniversary of the 2018 Parkland massacre that left 17 dead.

Shockley’s journals reportedly contained disturbing messages and Nazi imagery, including swastikas and phrases like “I hate you all DIE DIE DIE.”

Court-Imposed Restrictions

In addition to the prison sentence and probation, Shockley’s plea deal imposes several long-term restrictions:

• A lifetime ban on researching or viewing materials related to mass shootings

• A permanent prohibition on firearm ownership

• A requirement to install monitoring software on all electronic devices

• Mandatory mental health treatment and counseling

Prosecutors say the plea agreement ensures Shockley will remain under close supervision for years to come.

Troubled Background and Warning Signs

Authorities say Shockley was in the midst of a severe mental health crisis before her arrest. A guidance counselor had reported that the teen was struggling after the overdose death of her mother and had recently been bullied at school.

Shockley and her father were also badly injured in a 2022 car crash, which drew community support and donations for medical expenses. But as grief and isolation deepened, investigators say her obsession with mass killers grew — turning from fascination to intent.

Shockley reportedly discussed her plans in online chatrooms and even confided her fixation to a school counselor, triggering the tip that ultimately led to her arrest.

Community on Edge

The case has rattled the Mooresville community, which narrowly avoided what police described as a “potentially catastrophic act of violence.”

While Shockley’s plea deal spares the town a trial, local parents and educators say the incident underscores the growing threat of online radicalization, mental illness, and school safety concerns.

Shockley’s formal guilty plea is scheduled for November 24 in Morgan County Circuit Court.
