Macon Police Chief Mike Burns was interviewed Friday night outside Lauren Giddings' apartment for a weekly Fox News legal show with former judge and prosecutor Jeanine Pirro.
During the interview, Burns said investigators had sent about 200 pieces of evidence for analysis at the FBI and GBI crime labs, including pipes and drains from Giddings' apartment.
He said they had several persons of interest in the case and are "getting closer" to solving her murder.
He says one of their persons of interest, Giddings' neighbor, Stephen McDaniel, first came to their attention after Burns says he "inserted himself" into the search for Giddings and sought out media attention.
Telegraph reporter Amy Leigh Womack was also interviewed for the broadcast.
McDaniel is being held in jail without bond on what police describe as unrelated burglary charges. He was arrested the day after Giddings' body was found outside their apartment complex. He attended a hearing Friday morning in which his lawyer argued that the Bibb County District Attorney's office would have a conflict of interest in prosecuting McDaniel because he was an intern in the DA's office. The judge deferred ruling on the motion.
