A former Northview High School student was found guilty this week of the 2011 shooting death of her adoptive sister in the Ferry Pass, Fla. community.

Elena Janelle Rendel was sentenced to one year in county jail after being convicted of shooting and killing her 14-year-old adoptive sister Christina Marie Sneary in August of last year.

Rendel was tried for the crime as a youthful offender. Had she been charged as an adult, Rendel, who was 17 at the time of the shooting, she would have faced a sentence of up to a minimum 25-year mandatory prison stay. Rendel will was not given credit for her nearly one year spent in jail awaiting trial and will be subject to five years probation following her release.

According to officials with the Escambia County (Fla.) Sheriff’s Department, Rendell first told officers responding to the scene she had accidentally shot Sneary while trying to fire at a black male who had broken into their home.

Authorities said Rendell changed her story after further questioning and told officers the gun had gone off while she and her sister were playing with the weapon. Rendell later admitted to officers she shot Sneary in the neck during an argument between the two girls over a cell phone.
