No charges to be filed in fatal stabbing

Following a preliminary investigation by sheriff's office investigators and the local district attorney’s office, officials said no charges will be filed in connection to the boy's death.

"California law dictates that age, criminal intent, and knowledge of wrongfulness are factors needed to charge a child with a crime," the release said. "Based on the current investigation, there is no indication of negligence or criminal activity by any other party. We are heartbroken for the family of these two young children and share in their grief."

Officials said no further details are being released in the case and asked the family be given privacy as it mourns.
