Kendrick Castillo, considered a hero, was shot and killed while trying to block one of the gunman from shooting more people. Eight other students were injured.

Castillo's parents, along with victims and other family members, appeared in court for the formal filing of charges.

"It would have been easy for them to say, 'I'm not going to be in court today because in less than two hours we're going to have a memorial service for our son,'" said 18th Judicial District Attorney George Brauchler.

A huge procession and celebration of life was planned for Wednesday to honor Castillo who was set to graduate this month and attend Arapahoe Community College in the fall.

Erickson remains in custody without bond at the Douglas County Jail in Castle Rock. He was initially charged with 30 counts and that increased to 48 counts by the time he appeared in court on Wednesday. McKinney is facing the same counts.

Those charges include possession of a weapon on school grounds. Erickson was a student in the British English class where the shooting began. Rooms 107, 108, 109 have been identified in the investigation as part of the shooting scene.

No decision has been made on whether the death penalty could be applied to Erickson. Brauchler made it clear that it wouldn't be considered in McKinney's case.

"Juveniles never, ever get considered for capital punishment because the Supreme Court said no under the 8th Amendment," said Brauchler.

McKinney's attorneys are seeking to have the case against him moved back into juvenile court.

Erickson appeared in court with pink and black hair and glasses, wearing an orange jumpsuit with wrists and ankles shackled.
