2 teens charged in connection with fatal sucker-punch of 13-year-old boy at Moreno Valley school

RIVERSIDE COUNTY, Calif. (KTLA) -- Two 13-year-old boys accused in a brutal, on-campus assault in Moreno Valley that left their classmate with fatal injuries now face prosecution, authorities announced Thursday.

Both boys were charged with assault by means of force likely to produce great bodily injury, according to John Hall, a spokesman for the Riverside County District Attorney's Office. The juvenile petitions were filed on Sept. 18.

"At this time, those are the filed petitions in this case," he wrote in an email. "As with any case, should we receive updated information or evidence, we can amend to add, change, or file different charges."

Both students were arrested after the victim, identified only as 13-year-old Diego, was sucker-punched and critically injured at Landmark Middle School on Sept. 16, according to the Riverside County Sheriff's Department.

He was hospitalized for more than a week before being pronounced "clinically dead" on Wednesday. The teen's family plans to have his organs donated "to transform this tragedy into the gift of life for other children," a sheriff's news release stated.

Neither teenage suspect has been identified due to their ages, but the Sheriff's Department confirmed after Diego's death that both remained in custody at Riverside County Juvenile Hall.

The incident, which was filmed by a bystander, prompted outrage in the community, with many students and parents decrying the school's lack of action to prevent bullying.

Classmates told KTLA that Diego had been bullied previously.
