Sheriff Jenkins says that call saved lives.
Right now, Cevario is undergoing a mental evaluation at Frederick Memorial Hospital.
Cevario had allegedly planned to carry out the attack on April 5, according to her journal, which police say "clearly spelled out" plans for the bombing. Investigators found a shotgun with ammunition and materials used to make bombs, including pipes with end caps, fireworks, shrapnel, magnesium tape and fuse material. She also organized a timeline of events and expected outcomes and indicated she planned to die as part of the attack. 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.
An 18-year-old Maryland high school student is facing charges related to an alleged plot to attack her school in April using a shotgun and explosive materials.
Frederick County Sheriff's Office (THURMONT, Md.) - A Maryland teen accused of plotting a school shooting mentioned the Columbine High School massacre and the Sandy Hook Elementary School shooting in a diary discovered by investigators, according to authorities.
In a video Monday on the school district's YouTube page, Dr. Terry Alban, superintendent of Frederick County Public Schools, thanked the "courageous" parents for stepping forward.
"It shocks the conscience to see that someone of that age could be thinking like this", Jenkins said.
The teen could be charged with possession of incendiary material and explosive material with the intent to create a destructive device, according to law enforcement officials. The gun and other items were purchased legally, police said. In a statement, officials said the student had plans and equipment that would have "caused a significant life safety event" if she had "followed through with the threat". But when investigators went to her home, they found enough evidence to show "obvious intent was there", Jenkins said.
The Sheriff's Office has scheduled a 2 p.m. press conference to answer any additional questions about the case.
"The Sheriff's Office is extremely appreciative of the parent's actions in bringing this potentially deadly incident to the proper authority's attention, promptly, so that a positive conclusion could be achieved", authorities said. The bottom line is this: "We keep our school safe, and we will continue to work together as a community to keep it safe".
