1x3 - Vanished by the Lake

Remi Bouchard is arrested over Chloe's disappearance, just like he was fifteen years ago. Lise is not sure he is guilty, especially when he informs her that the former prosecutorial investigation against him was biased and certain elements were left out. The investigator at that time was none other than Lise's own father, who has since committed suicide. Who is lying and who is telling the truth?
