Chris Aguilar, 16, spoke little during his initial court appearance in Phoenix, while loved ones of Michael Montoya, 16, broke down into sobs.

Scores of mourners clad in the Phoenix school's colors gathered as the sun set while they memorialized a 16-year-old stabbed during class.

The vigil was held days after the victim, Michael Montoya II, was stabbed and killed at Maryvale High School. The suspect in the case is being charged as an adult.
