The Putnam County sheriff's office says a third suspect has now been taken into custody on two counts of aggravated robbery and two counts of especially aggravated kidnapping. 25-year-old Carlos Darnell Dixon of Lascassas Road in Murfreesboro is accused of being the man who held a gun on two victims who were lured into an apartment at Tech Village early Sunday and robbed. Authorities say Dixon turned himself in at the sheriff's office after learning that Tennessee Tech police had taken warrants out on him. He has an initial court appearance on Wednesday. Two other suspects in the case, Jimmie Blair and Christian Dawn Pryor, were arrested early Monday for allegedly assisting Dixon in the robberies.
