Police say Keshawn Brooks was fatally stabbed by 18-year-old Giovanny Montelongo as he tried to snatch his backpack around 3:25 p.m. Thursday.
The attack occurred in the 2800 block of Santa Fe Avenue as Brooks walked home from Cabrillo High School, a Long Beach Police Department statement said.
Montelongo was arrested at a residence in the 1700 block of West Columbia Street later Thursday.
Keeyon Layton, Brooks' father, said his son was an innocent victim.
"My son was not a gang member,'' Layton said Thursday night. "This was murder ... and he didn't deserve this.''
