EXCLUSIVE: An Arrest Is on the Horizon on 'Killing Fields'

ET has your first look at the dramatic moment Det. Rodie Sanchez has dreamed about for decades.

As the detectives continue to investigate the murders of
Eugenie Boisfontaine and Curtis Smith on Discovery Channel’s true-crime docuseries,
Killing Fields, another case is reopened, potentially providing a major
break in these cold cases.

On an all-new episode of this real-time series, which inches
closer to the season two finale, the DA reopens a 15-year-old case involving
the death of informant George Barrett. Killed in his home in 2002, Det. Rodie
Sanchez has always suspected local businessman Tommy Francise, also suspected
of killing Smith
, was responsible for Barrett’s death.

All season has seen the investigative team at the Iberville
Sheriff’s Office get closer and closer to bringing justice to these victims, and
now, it may seem that an arrest is on the horizon. ET has your first look as
authorities move in on Francise. “All these years, I’ve dreamed of this day,”
Sanchez says in the clip.

Executive producer Tom Fontana promised season two would remain dedicated to following Det. Sanchez and Aubrey St. Angelo, who
continued to investigate these cases despite not being able to make an arrest
in season one. “They take a long time,” Fontana said. “But the detectives are
so wonderfully determined.”

And if there is a dramatic conclusion, “the effect of that
wouldn’t be as awesome if we didn’t know who Rodie was at this point,” Fontana
said. Indeed, he’s right -- and let’s hope that Sanchez might finally be able
to rest easy!
