The 17-year-old detailed her plans to carry out the shootings in her notebook while at one point saying she also wanted to blow up the dinner hall.
The teenager, who attended Radnor High School in Pennsylvania, was arrested on Monday after staff discovered her plans.
Police said the girl had a “fascination” with Eric Harris and Dylan Klebold who carried out the Columbine High School massacre in 1999 while planning her own mass killing.
“I could be the first female shooter,” the student, who has not been identified, wrote in her schoolbook.
The student is currently undergoing psychiatric evaluation. MIRROR
