The new indictment includes charges of first and second-degree murder as well as accessory to murder.

Last year, a federal grand jury in Sacramento returned a four-count indictment against Christopher Ross, Juan Carlos Vasquez-Orozco, Ramiro Bravo Morales, and Jorge Lamas. All four were charged with conspiracy to grow marijuana. Vasquez and Morales are also charged with being an illegal alien in possession of a firearm.
