Chris Aguilar, 16, is accused of stabbing another student to death inside a classroom at Maryvale High School. On Thursday, a judge ruled Aguilar will remain in jail for at least another month while his housing is reassessed. Aguilar is being held on a $500,000 cash bond.

PHOENIX - The teenager accused of a deadly stabbing at a Phoenix high school pleaded not guilty in court during an arraignment hearing on Wednesday.

Chris Aguilar, 16, is accused of first-degree murder in the killing of 16-year-old Michael Montoya II. Aguilar is being charged as an adult.

The backstory:

On Aug. 19, the Phoenix Police Department said an officer who was working as a School Safety Officer at Maryvale High School was alerted by school staff members at around 10:54 a.m. that an assault had happened inside a classroom.

"The officer was directed to the administration building, where he detained one of the students involved," police said. "A second student was located by officers and firefighters suffering from multiple stab wounds. He was quickly treated on scene and rushed to the hospital, where he died from his injuries."

Aguilar was indicted by a grand jury on Aug. 28 for his alleged role in the deadly stabbing.
