A man who allegedly shot and killed an 18-year-old Navy sailor in San Diego’s East Village, then fled the state, pleaded not guilty Friday to murder. Ta’Kari Terell Benness, 20, was arrested on Oct. 16 in St. Cloud, Minnesota, nearly two months after police say he shot operations specialist seaman apprentice Albert Soto, who was assigned to the San Diego-based destroyer USS Pinckney.
