Among his convictions is first-degree felony murder for the killing of student Kendrick Castillo, 18, who died lunging at his attacker in order to save classmates.
Background: Erickson's convictions come after accomplice Alec McKinney pleaded guilty last year to murder, attempted murder, conspiracy and weapons charges and was given a life sentence plus 38 years for the attack — which left eight other students wounded.
McKinney was 16 at the time of the shooting, so he can seek parole after 40 years, Reuters notes. Erickson was 18, so he's set to receive a mandatory life sentence without parole, AP reports. He's due to have a sentencing hearing on Sept. 17.
