On Dec. 12, 2015, former students Brooke Higgins and Sienna Johnson plotted to commit first-degree murder against classmates and staff at Mountain Vista. However, through “Text-A-Tip,” a texting hotline where students can anonymously express their concerns to deputies, officials were able to stop the credible threat.
Almost a year later, on Dec. 20, 2016 Brooke Higgins pleaded guilty to one count of conspiracy to commit murder in the first degree and murder solicitation in the first degree, both felonies.
Along with a plea agreement, Higgins accepted a sentence of three years in the Division of Youth Corrections, the state’s juvenile detention system, and will get credited for the year she has spent in jail since her arrest. Higgins also agreed to four years of supervision upon her release from juvenile detention for the adult charge. A formal sentencing is set for early February.
Prosecutors say if Higgins successfully completes her sentence, she could have the adult felony conviction sealed from her record.
Following the court date, on Jan. 6 the Affidavit surrounding the case was released. In doing so, it discusses the plans of Johnson and Higgins as well as personal background information in regards to what led them to take action against their colleagues.
