An 18-year-old girl, who allegedly wrote about identifying as a male and had a “shrine” to mass killers, was arrested and charged this week for allegedly planning a mass school shooting at Mooresville High School in Indiana.
Trinity Shockley, a female who allegedly identifies as a “transgender male,” was charged with conspiracy to commit murder and felony intimidation after one of her friends sent information to the FBI’s Sandy Hook tipline. The tipster stated that a friend was planning on carrying out a mass shooting and had access to an AR-15 rifle, according to police.
After the tip came in, the FBI tracked down disturbing messages Shockley allegedly sent under the name “Jamie” on social media platforms Snapchat and Discord. The messages detailed plans for a mass shooting along with photos of a bulletproof vest and AR-15 rifles. In one of the messages, Jamie wrote that she had been planning the school shooting for a year.
According to investigators, Shockley spoke with a school counselor on Tuesday and disclosed that she was sexually attracted to the 19-year-old shooter who killed 17 people and wounded 17 more at Parkland High School in Florida in 2018.
In 2022, Shockley was hit by a suspected drunk driver while walking to the bus stop. The crash fractured her skull, broke her femur and arm, and caused two brain contusions, according to a report from WRTV. Shockley allegedly told investigators that she was teased about the accident. “Trinity found out later that the male who struck her with his vehicle, committed suicide. She felt like she killed him, but she knows she did not. She blamed herself for him killing himself,” the arrest affidavit states.
Shockley sought mental health help when she was a freshman, but a school official told police that her father, Timothy, did not allow her to continue receiving mental health assistance. Shortly after Schockley turned 18 last year, she signed herself up for mental health assistance.
Authorities executed a search warrant at Shockley’s home, where she lives with her father. During their search, authorities said they found “a collage” on the wall of multiple mass shooters and found three notebooks belonging to Shockley.
“Each notebook depicted swastikas, the words ‘kill,’ ‘bang,’ ‘I hate you all DIE DIE DIE’ among other obscenities,” the arrest affidavit stated.
According to police, one of Shockley’s notebook entries — dated December 16, 2024 — stated, “My name is Dex I am eighteen years old. Born on October 26th 2006. I currently live with my father, my mother passed away. I am aslo [sic] a transgender male. I have a lot of homicidal thoughts.”
A January 9, 2025, entry read, “I am death, destroyer of worlds.” A few days later, the writer penned, “These thoughts wont stop. I want to hurt others. All of the time! I want to hurt others. I wish people around me knew about my bad thoughts. I love violence.”
Shockley is being held without bond at the Morgan County Jail, WTHR reported.
