It's been a few months since fans watched as Iberville Parish detectives worked to try and find out who murdered Eugenie Boisfontaine, but they may be able to revisit the mystery when Killing Fields officially returns to Discovery in the Fall.

The show is scheduled to return to the cable channel for its second season this fall, after Rodie Sanchez, Aubrey St. Angelo and others were unable to make a conclusion about who had murdered Eugenie Boisfontaine 30 years before, in a case that was initially investigated by Sanchez, but wound up going cold. The case was reopened and examined with fresh eyes and the new improvements in investigative technology and DNA testing.

However, by the end of the first season, there still wasn't a prime suspect who the detective were able to arrest for the crime. Now, in the second season, the detective will be back as they continue trying to uncover just who murder Eugenie.

Back when the season ended earlier this year, the detectives working the case did an interview where they admitted they hadn't solved the case yet, but they were working on new leads they had received.

"Police work cannot be solved in a six-hour series," St. Angelo said at the time. "Some of these leads could have validity to them, but it's tough working all our other cases and chasing all the leads on this down, too."

At the time of the show's first season coming to an end, Eugenie's ex-husband had been the prime focus of the investigation, but had refused to meet with detectives face-to-face. He did eventually speak with them, but they had to use the DNA sample for him that had been accrued covertly, and the inconclusive results made him no longer a suspect.
