CASTLE ROCK, Colo. -- Colorado prosecutors have charged the students suspected of opening fire at their school with murder and attempted murder and other counts, and are pursuing adult charges against the younger suspect.
The shootings at the STEM School Highlands Ranch on May 7 killed one student and injured eight others.
The accused gunmen, 18-year-old Devon Erickson and 16-year-old Alec McKinney, were arrested at the school and investigators said they opened fire inside using handguns.
A memorial service for the student killed, 18-year-old Kendrick Castillo, is scheduled for Wednesday afternoon at a Highlands Ranch church. Castillo and two other students have been credited with tackling one of the gunmen, disrupting the attack.
