Mooresville (USA) - Valentine's Day drama: An 18-year-old girl was arrested in the US state of Indiana for allegedly planning a massacre at her school!

18-year-old Trinity Shockley was arrested Thursday and now faces serious charges, including conspiracy to commit murder and threatening to commit acts of terrorism, FOX 59 reports.

The young woman allegedly planned a bloody shooting at Mooresville High School this Friday - but police were able to stop her plan in time thanks to assistance from the FBI.

A search of her home turned up frightening evidence, including AR-15 magazines and a bulletproof vest.

According to court documents obtained by FOX 59, the 18-year-old was in love with Nikolas Cruz - the man who shot and killed several people at Parkland High School on Valentine's Day 2018.

The teenager had an entire photo album of him and other criminals.

Investigators also found conversations about the planning of the rampage on Trinity's Discord and Snapchat account.

Apparently, bullying played a major role in the deterioration of her mental state.

Despite her efforts to seek professional help, she was apparently not taken seriously by her family or her school.

A few years ago, Trinity was in the headlines herself, but back then she was the victim: in 2022, she was hit by a drunk driver and suffered serious injuries.

The entire community supported her at the time by raising money for her recovery via GoFundMe.

Now the 18-year-old is sitting in Morgan County jail without bail - even though she was previously celebrated as a brave survivor.
