Sienna Johnson gets 5 yrs in juvenile detention

DENVER — A judge accepted a plea agreement that will see the second teen involved in the Mountain Vista High School shooting plot incarcerated in a juvenile detention facility for five years on Friday morning. 

Sienna Johnson in June pleaded guilty to a juvenile count of conspiracy to commit murder and an adult count of felony menacing.

She will serve five years in the Division of Youth Corrections on the conspiracy charge, and will not get credit for any time she has already served since her arrest.

On the menacing charge, the two sides agreed that Johnson will serve four years of probation upon her completion of her youth corrections sentence.

Though the conspiracy to commit murder charge is the same that Johnson’s accomplice in the plot, Brooke Higgins, pleaded guilty to last year and was sentenced for in February , Johnson agreed to a longer sentence than Higgins, though Higgins' sentence carries different parameters.

Higgins was sentenced to three years in Youth Corrections, but received credit for 409 days served. She was also assigned four years of probation and mental health treatment upon her release, as was Johnson.

As a stipulation of her probation on the menacing charge, Johnson will have to go through a drug and alcohol evaluation and a mental health evaluation upon her release from the Division of Youth Corrections.

In court on Friday, Johnson told a federal judge she isn't the same person she was when she and Higgins concocted the shooting plot.

"Your honor, I know what I did is wrong and I know the impact it has had on the community and Mountain Vista," Johnson told the judge. "I'm not the same person I was then. I have the opportunity to change."

She also promised the judge she won't be seen in court again past her re-evaluation as an adult in 2020.

Multiple family members testified on Johnson's behalf, including her uncle and father. 

"I believe she can have a wonderful life. I love her and I will always be there for her," Mark Moore, Johnson's uncle, said.
