On Monday, authorities said that an 18-year-old student meticulously planned a mass shooting at her high school in which she intended to die

A plot to shoot:

On Thursday, Frederick County Sheriff Charles Jenkins said at a news conference that they found at Nichole Cevario’s home in Thurmont a shotgun, ammunition and bomb-making materials including nails and fireworks.

Jenkins added that there’s no evidence that anyone else was involved.

According to a statement issued by the Frederick County sheriff’s office, Cevario was removed from the classroom and turned over to investigators after one of the teen’s parents notified Catoctin High School officials Thursday of a potential threat of violence. Officials said that Cevario was later taken from the school to a hospital for an emergency evaluation and remains hospitalized.

Jenkins said: “This attack was prevented by the parents, who stepped forward.”

Officials said that Cevario’s journal “clearly spelled out” detailed plans for an attack she was working on for some time, including a timeline of the attack with her expectations for each stage. The sheriff said that she had set April 5 as the day of the attack and she was acquiring the materials and compiling details about school emergency procedures associated with drills conducted by school staff and on the school resource deputy.


Jenkins added that Cevario’s diary showed “evidence of mental health issues, emotional issues.” However, there was no indication that bullying was an issue but it showed “a lot of frustration in her personal life.”

Investigators think they’ve eliminated any threat to the school and community as they believe Cevario was working alone. Explosive materials were located during the investigation, but they weren’t combined in a form that created explosive devices.

A warrant was issued charging Cevario with possession of explosive material with intent to create a destructive device and possession of incendiary material with the intent to create a destructive device, but it won’t be served until she’s released from the hospital.
