Both suspects in the STEM School shooting appeared separately in court Wednesday morning to be formally charged in connection to the May 7 attack that killed one student and wounded eight others.

The charges are reportedly counts of murder and attempted murder as well as other counts of arson, theft and weapons possession, according to electronic court records. The judge has suppressed almost all information in both cases and will hear arguments on the matter June 7.

Both suspects are being held with no bond.

Unlike his initial court appearance, 18-year-old Devon Michael Erickson appeared more involved in Wednesday’s proceedings. While he looked down with his face hidden by his dyed hair before, Erickson’s face was visible in the latest proceeding and he looked forward toward the judge while attorneys discussed the case.

District Attorney George Brauchler addresses the media after STEM School Highlands Ranch shooting suspect's 18 year old Devon Erickson and 16-year-old Alec McKinney facing criminal charges made court appearance's at the Douglas County Courthouse May 15, 2019, in Castle Rock, Colo.

Following the hearing, District Attorney George Brauchler said he has done no analysis on whether to pursue the death penalty in Erickson’s case.

Brauchler said 16-year-old Alec McKinney, who is listed in court documents as Maya Elizabeth McKinney, would be charged as an adult. The defense wants the case sent back to juvenile court. McKinney is currently held at a juvenile facility and will remain there, regardless of the adult charges.

Douglas County officials initially identified the juvenile suspect as male and later as female. Instead, McKinney uses male pronouns and prefers Alec as his first name.

The charges in the case were filed on the same day a memorial service was scheduled for Kendrick Castillo, the 18-year-old student who was killed while trying to stop the shooting at the Highlands Ranch school.

Brauchler said he spoke with Castillo’s parents at the hearing.

“It would have been easy for them to say ‘I’m not going to make it to court today because in less than two hours, we’re about to have a memorial service for our son,’“ he said. “But from the word ‘Go,’ they have made it clear, ‘Our intention is to be here for every single hearing,’ and today I think is a good example of that.”
