In what’s become an increasingly grim couple of weeks for reality television, a doctor working on TF1‘s Koh-Lanta, France’s version of Survivor, has committed suicide. Dr. Thierry Costa’s death comes a little over a week after contestant Gérald Babin died from a heart attack during filming of the first episode of the show’s 16th season in Cambodia. Production had already been shut down on Koh-Lanta and resulted in the cancellation of the entire 16th season. In a suicide note he asked be made public, Costa said he was confident he had treated Babin “as a patient and not a contestant” but said he was distraught by “false accusations and assumptions” in the media, according to local reports. Last Friday, Koh-Lanta producer Adventure Line Productions, a subsidiary of Zodiak media, said it would sue for defamation after information from an anonymous source, which called into question the on-site response of the production team and the doctor, was published by French media. A manslaughter inquiry has been opened into Babin’s death. Koh-Lanta started airing in 2001 and is one of leading network TF1′s flagship series, drawing an average of 7.4M viewers.
