On the penultimate episode of Killing Fields season two, the detectives move closer to making an
arrest -- a pivotal step in closing the case of Curtis Smith, who went missing
in 1991 -- to put Tommy Francise behind bars. It’s something Det. Rodie Sanchez
has been dreaming about for 26 years as he’s worked tirelessly to bring justice
to Smith and his family.

In order to arrest Francise, the Iberville Parish Sheriff’s
Office must present their case to the legal team, including Special Prosecutor
Tony Clayton. Once he gives the “OK,” the team can move in on their suspect. Of

him -- and he’s not sitting idly by.

Disappointed that they weren’t able to make an arrest in the
first season, while investigating the 1997 homicide of Eugenie Boisfontaine,
executive producer Tom Fontana stuck with Det. Sanchez and his partner, Det.
Aubrey St. Angelo. “This is a cold case, so it’s got even more problems working
against it,” he told ET ahead of season two. “But the detectives are so
wonderfully determined.”

And the show’s commitment to Iberville Parish and the
detectives’ commitment to solving these cold cases is about to pay off. “To see
their genuine commitment to solving the crime is really fun to watch,” Fontana
said -- and indeed it has!
