Classmates at Roosevelt Middle School in Glendale were stunned after a 13-year-old boy was struck and killed by a school bus on Thursday.
Authorities continued to investigate the crash.
One item left at a memorial at the site was a white bike, known as a ghost bike, placed there by Danny Gamboa of Long Beach, who regularly leaves ghost bikes at sites where bicyclists have either been injured or killed in crashes in the L.A. area.
The Los Angeles County coroner on Friday identified the boy as Jonathan Hernandez, who died shortly after being struck by, and trapped underneath, a school bus Thursday afternoon at the intersection of Columbus Avenue and Riverdale Drive.
He was previously identified by Glendale police as being 14.
Grief counselors were at the campus for friends and teachers who knew Jonathan, who was described as well-liked and a student who excelled academically.
