Joaquin Morales pleaded not guilty to three counts of vehicular manslaughter on 4/4. Morales, 61, was driving his big rig truck down Highway 154 and was unable to stop. The truck eventually crushed a home at the back of a parking lot behind Palapa Restaurant. Inside, Leon Leonel, 22, Lorena Tellez Pacheco, 26, and 8-year-old Jaciel Tellez, were dead. Morales, who has a history of traffic citations, will be back in court next month.
