Authorities are investigating whether a child who remains in critical condition after a violent assault at a Moreno Valley middle school had been the target of bullying before the attack. The assault took place Monday afternoon at Landmark Middle School and resulted in the arrest of two 13-year-old students. Riverside County sheriff’s investigators said they are aware of allegations of bullying involving the victim and are working with the school to conduct a “thorough investigation,” Deputy Robyn Flores said Thursday in an email.
