An Indiana teen who had an “obsession” with the school shooter who murdered 17 people exactly seven years ago is accused of plotting another Valentine’s Day massacre, authorities say.

Trinity Shockley, 18, was arrested following an FBI tip, where investigators said she planned to use an AR-15 to shoot up Mooresville High School southwest of Indianapolis.

Trinity Shockley allegedly wanted to prove she was the ‘number one fan’ Nikolas Cruz, the convicted Parkland school shooter, with a Valentine’s Day copycat attack
