Brooke Higgins and Sienna Johnson, both 16, have been charged with conspiracy to commit first-degree murder under extreme indifference and conspiracy to commit first-degree murder after deliberation, 9 News reports. The two girls were thwarted before executing a Columbine-style attack they'd allegedly planned on Mountain Vista High School in Castle Rock, Colorado.
According to Westword, both Higgins and Johnson are being charged as adults. In a court hearing yesterday, prosecutors said the girls had a "fascination" with the 1999 Columbine shooting and that Johnson had written in her diary Higgins was "someone who's got what it takes" to execute such an attack and that together they'd be "unstoppable" in making school "a living f*cking nightmare."
ABC 7 reports Higgins allegedly used her phone to research female mass shooters and whether or not minors could purchase guns at gun shows. The defense argued having a fascination with guns and Columbine is not a crime: "This is a thought crime, at best," Higgins's lawyer said.
