A 14-year-old Claremont boy, Nathaniel Geurts, who is a suspect in his sister’s death, will be arraigned on December 9, according to the Los Angeles Superior Court.

Nathaniel, who is in custody for the stabbing death of 15-year-old Aspen Geurts, appeared in court on Monday morning before his arraignment was pushed. He will appear in Pomona Superior Court at 8:30 a.m. on December 9 in department F. The boy was remanded into custody, and his bail was set at $10 million.

The boy, who will be tried as an adult, is accused of stabbing his sister with a kitchen knife on November 4 in the back yard of the family home, located on the 300 block of Andover Drive. Neither parent was home at the time.

He was found a short time later walking away from the scene holding the alleged murder weapon and was arrested.

Lieutenant Mike Ciszek of the Claremont Police Department would not elaborate on a possible motive.

“The motive is still kind of shaky, it vacillates,” he said. “It’s kind of hard to say what’s going on.”

Lt. Ciszek said there was no record of mental illness, but said the boy “exhibited a questionable mental status” when he was taken into custody.
