The shooting was reported at 10:44 a.m. near Burrows and Holyoke streets.
The victim was pronounced dead at the scene, police spokesman Officer Albie Esparza said.
The shooting prompted the lockdown of nearby E.R. Taylor Elementary School, according to Angie Oropeza, a secretary at the school.
Oropeza said school staff members were told not to let the children go outside but that classes could continue normally.
