(Trent Nelson | The Salt Lake Tribune) One of the police officers who questioned Gabby Petito in Moab weeks before she was killed by her boyfriend was “fundamentally biased” against her — and because of that, he failed to accurately assess the dangers she faced, according to a lawsuit filed Thursday. The attorneys representing Petito’s parents in the case are basing that new claim on an allegation from a woman who says the officer, Eric Pratt, had threatened to kill her after their relationship ended, while he was the police chief in another rural Utah town.
