Teen Accused In Murderous Plot On High School In Court

CASTLE ROCK, Colo. (CBS4) - One of the teens accused of plotting a murderous attack on a high school in Highlands Ranch has waived her right to a preliminary hearing.

That put Brooke Higgins directly into a reverse transfer hearing, the outcome will be one of the most significant in the entire case. Higgins is one of the teenage girls accused of threatening students and staff at Mountain Vista High School.

Sienna Johnson and Higgins were both 16 years old when they were arrested in December 2015 for an alleged murder plot at their Highlands Ranch school.

Higgins has been accused of plotting to kill student and staff at the high school, even writing about how she wished she could have taken part in the April 1999 Columbine High School attacks.

Prosecutors have charged those teenagers as adults and the defense attorneys have asked for a reverse transfer -- they argue the teens should be tried as juveniles where the punishment is far less severe.

Her attorneys claim that her crime is a "thought crime" at best. Higgins has been charged as an adult with conspiracy to commit first-degree murder under extreme indifference and conspiracy to commit first-degree murder after deliberation.

They remain in custody on $1 million bond each.
