A 15-year-old McLoud girl was formally charged Tuesday in Pottawatomie County District Court in the shooting death of 16-year-old McLoud sophomore Kaylen Thomas.

Pottawatomie County prosecutors on Tuesday filed a first-degree manslaughter charge in the case.

The teen, Isabella Irene Sabas, is charged as youthful offender, court records show.

First Assistant District Attorney Adam Panter said after a full review of the case, Sabas is now charged with first-degree manslaughter, which the most serious offense they can charge for someone that age.

Panter said evidence in the case alleges Sabas, a McLoud High School student, recklessly handled a loaded firearm that discharged, causing the death of Thomas.

With a youthful offender charge, a judge determines, upon a conviction, if the teen is sentenced as an adult or a juvenile.

The shooting occurred at a home in McLoud on Oct. 5.

A 17-year-old boy who was also there at the time of the shooting is charged as a juvenile delinquent, Panter said. He faces a juvenile charge of accessory to manslaughter in the case. Because his case is going through the juvenile system, his name has not been released.

Panter said both of the teens remain jailed in juvenile detention centers.

After the shooting, more than 20 counselors were at McLoud Schools for students and staff to provided support.

Thomas was a dedicated young girl, whether in the classroom or on the basketball court, said McLoud High School Principal Rhonda Hockenbury.

A next court date for Sabas is not yet listed on court records. An attorney of record also is not yet listed.
