A second teenager is now charged as a youthful offender in connection with the fatal shooting of a McLoud teenager back in October, while the youthful offender case against the first teen charged in November was amended Friday to reflect a more serious charge, court records show.

According to the information filed by District Attorney Allan Grubb's office, Alano Marcelo Silverhorn, 17, was charged in Pottawatomie County District Court Wednesday with murder in the second degree, a felony. Silverhorn is charged as a youthful offender.

With the youthful offender felony filing, the previous juvenile charge was dismissed, the case file shows.

In the new youthful offender case, Silverhorn is accused, on or about Oct. 5, of being in the commission of a felony at the time of the killing of K.D.T. by being in possession of a firearm, court records show.

The charge reflects that possession of the firearm “involved conduct that created what a reasonable person would realize was an immediate and extremely high degree of risk of death to another person and which the defendant engaged in with contemptuous and reckless disregard of, and total indifference to the life and safety of another, regardless of human life, although it was done without any premeditated design to effect the death of any particular individual.”

Upon conviction, the charge is punishable by 10 years to life in prison.

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

The case involves the death of 16-year-old McLoud sophomore Kaylen Thomas, who died on Oct. 5 after being shot in the head while at a classmate's house in McLoud.

Back in November, Isabella Irene Sabas, 15, was charged by previous District Attorney Richard Smothermon's office with first-degree manslaughter in the case and was accused of recklessly handling the firearm that discharged.

On Friday, court records show that Saba's case was amended by Grubb's office to reflect a second-degree murder charge, the case record shows.

The next court date for Silverhorn is not yet listed, while Sabas is scheduled for a preliminary hearing next week.

Watch for updates on both cases.
