Police in California say the suspect in a mass shooting during Lunar New Year celebrations is now dead. SWAT officers surrounded a white van for hours today, trying to determine whether a man barricaded inside was the person responsible for taking the lives of 10 people. Police say the 72-year-old suspect died at the scene from a self-inflicted gunshot wound. Investigators found several items inside the van connecting him to the crime scene.
