EXCLUSIVE: A Key Witness Finds Herself in Danger as Detectives Grow Closer to Solving the Case on 'Killing Fie

At least one unsolved homicide may be solved before the end of Killing Fields season two. As Detectives Rodie Sanchez and Aubrey St. Angelo get closer to solving the homicide of Curtis “Cochise” Smith, who first went missing in 1991, tensions rise over the safety of a key witness. Arlene, who was close to the suspect (local businessman Tommy Francise) at the time of Smith’s disappearance, may be the strongest lead the detectives have in connecting Francise with the homicide.

But the remains of a John Doe first discovered in 2005 and Arlene’s testimony just may be the missing pieces Det. Sanchez and St. Angelo need. But in the sneak peek, getting to Arlene may not be as easy as they thought. The authorities discover that news travels quickly in Iberville Parish, Louisiana, as they watch Francise follow Arlene into a grocery store. And now, they have to consider everyone’s safety before moving in on their prime suspect. Killing Fields airs Tuesdays at 10 p.m. ET/PT on Discovery Channel.
