Keshawn Brooks was walking home from Cabrillo High School Thursday before 3:25 p.m. when he was confronted and attacked by another teenager, according to the Long Beach Police Department.

He was stabbed multiple times across the street from Stephens Middle School in the 2800 block of Santa Fe Avenue as school was letting out, a news release from the department stated.

The older teen then fled the scene.

Keshawn was transported to an area hospital by paramedics from the Long Beach Fire Department.

He later died from his injuries.

Keshawn’s grief-stricken father spoke out about his son’s killing at an evening press conference.

“My son was not a gang member,” Keeyon Brooks told reporters. “This was a murder done outright. And he did not deserve this.”

Brooks also thanked the bystanders who helped his son in the wake of the assault.

“To the people who came to his aid, I would like to thank you very much,” he said. “It pleases me that he was not alone during his time of death.”

A short time after the attack, officers ascertained the whereabouts of the teen suspected in the stabbing, 18-year-old Giovanny Montelongo, according to the release.

Montelongo, a Long Beach resident, was taken into custody at a residence in the 1700 block of West Columbia Avenue.
