One teen boy stabbed another to death in a west Phoenix classroom on Aug. 19, according to court records.

Phoenix officers responded to Maryvale High School at around 10:54 a.m. after receiving a call about a stabbing and found a boy with multiple stab wounds.

Michael Montoya II, 16, was taken to St. Joseph’s Hospital, where he was pronounced deceased at noon, according to a police statement and court records.

Chris Daniel Aguilar, 16, has been charged with second-degree murder, according to court records.

Here’s what we know so far about the fatal stabbing.

What led up to the stabbing?

Multiple teens told police that Montoya had robbed Aguilar of a firearm, with one saying that Aguilar and his twin brother talked about killing Montoya after the alleged robbery, according to court records.

A girl told police that Aguilar normally sat behind her in class but instead sat next to Montoya shortly before punching him multiple times, court records said.

What weapon is Aguilar accused of using?

The girl who normally sat in front of Aguilar told police she saw him pull out a pocketknife before stabbing Montoya three times, according to court records. Another person saw Aguilar drop the knife outside the classroom, records said.

A school security guard collected a four-inch folding knife that had Aguilar’s name etched on the handle and placed it in the principal’s office, court records said.

What did witnesses tell police about the stabbing?

Two teachers also saw the stabbing, court documents said. They identified Aguilar as the aggressor and said Montoya was unable to defend himself, the records said.

Another person told police they saw Aguilar attack Montoya while he sat at a table and that Montoya tried to run away but fell to the ground when Aguilar continued assaulting him, records said.

That person told police that they saw Aguilar run out of the classroom after the assault, documents said. The same person said they used Montoya’s phone to call 911, records said.

A witness video-recorded the incident, records said.
What happened to Aguilar?

After school security and Phoenix police detained Aguilar, he was taken to Maryvale Hospital to treat a cut on his right hand, court records said.

When he was released from the hospital, Aguilar was taken to Phoenix police headquarters, where he asked for his parents, records said. After his parents arrived, Aguilar told police he didn’t want to speak with investigators and requested an attorney, according to court records.
What charges does Aguilar face?

Aguilar has been charged with one count of second-degree murder as of Aug. 20.

Under Arizona law, juveniles between 15 and 17 years old are required to be tried as adults if charged with murder or a violent felony.
Where is Aguilar now?

Aguilar is in custody. During his initial court appearance, he was ordered held on a $500,000 cash-only bond, meaning the whole amount must be paid in cash up front. Such a bond limits a defendant from relying on a bail bondsman and the use of collateral.

Should Aguilar make bail, he would be required to have electronic monitoring attached before being released.

When is Chris Aguilar due to appear in court?

Aguilar’s next scheduled hearings are on Aug. 26 and Aug. 28 in Maricopa County Superior Court.
Where is Maryvale High School?

Maryvale High School, part of the Phoenix Union High School District, is at the corner of North 59th Avenue and West Osborn Road in west Phoenix.
