Los Angeles County prosecutors said Monday that the boy was reported missing by his family March 30 after he boarded a train to visit the coach in Lancaster, north of Los Angeles. He wasn’t heard from again. His body was found several days later in Ventura County, northwest of Los Angeles. “No parent should ever have to endure the unimaginable pain and sorrow of learning their child has been murdered,” Los Angeles County District Attorney Nathan Hochman said in a statement. “Sexual predators … will be held accountable and prosecuted to the fullest extent of the law.” Prosecutors said Mario Edgardo Garcia-Aquino was charged with one count of murder, with the special circumstance allegation of murder during the commission or attempted commission of lewd acts with a child. The charges make him eligible for the death penalty. Prosecutors said Garcia-Aquino is accused of killing the teen, Oscar Omar Hernandez, and then dumping his body along the roadside.
