COLORADO SPRINGS, CO – A second teenager who was facing charges for threatening to kill students and staff a Colorado high school was in court Wednesday.
17-year old Sienna Johnson pled guilty to conspiracy to commit murder and felony menacing.
In December 2015, Johnson, and co-conspirator Brooke Higgins, had planned to go on a killing spree at Mountain Vista High School in Douglas County.
Johnson is expected to spend three years in the juvenile detention system followed by probation.
In February, Higgins also pled guilty and will serve a similar sentence.
