Only one of the four suspects charged with murder in the July 8 death of Hall County Sheriff’s Office Deputy Nicolas Blane Dixon appeared in court Tuesday morning for a formal arraignment. London Clements, 17, appeared with his attorney Dan Sammons before Superior Court Judge Jason Deal. Sammons entered a not guilty plea on his client’s behalf. The other three co-defendants — Hector Garcia-Solis, Brayan Omar Cruz and Eric Edgardo Velazquez — waived arraignment and filed not guilty pleas, according to the Hall County District Attorney’s Office.
