Biography
Sofia Curtis was the supervisor of the swing shift and had to work a case with Gil Grissom while Ecklie was being promoted. Ecklie later had Sofia evaluate Grissom's team in the hopes that she would give him enough ammo to break up Grissom's team. Sofia found no lacking in Grissom's leadership or the ability of the night shift to function. Ecklie broke up the team anyway and Sofia was demoted and moved as CSI to the night shift under Grissom. She decided that lab politics wasn't her thing and transfered to the Las Vegas Police Department as a detective. She participated in the arrest of suspected drug dealers that were firing automated weapons at police officers. One officer was killed by friendly fire and Sofia suspected that she might have fired the fatal shot. That almost broke her up. It was later discovered that Captain Brass had fired the fatal round. Sofia Curtis still works as a detective in the night shift.
