LAS VEGAS (KSNV) – Six videos presented as evidence to a grand jury showed the lead up and aftermath of a beating that killed a Rancho High School teenager. A panel last week indicted four of the nine teenagers accused in the beating death of 17-year-old Jonathan Lewis on November 1. They are Dontral Beaver, 16; Damien Hernandez, 18; Treavion Randolph, 16; and Gianni Robinson, 17. The four teens are each charged with second degree murder. They appeared in court on Thursday for an arraignment and each pleaded not guilty. The other five teens remain in juvenile court awaiting a certification hearing to know if they will be tried as adults.
