MONONGAHELA, Pa. – (WPXI) – A former police officer accused of sexually assaulting a woman in a police cruiser while he was on duty is heading to trial. The alleged incident happened while Dustin Devault, 47, served as an officer in Monongahela. He then worked as a part-time officer with Forward Township and Highmark but is no longer at either department. Devault first met the woman during a traffic stop, a grand jury found. The two met and texted several times after. The woman told authorities it was her understanding that Devault was going to help her become a police officer and seek treatment for a loved one who was suffering from substance use, according to investigators. On one occasion that the two met, Devault allegedly showed up in full uniform in an unmarked car. While in the car, the woman claims Devault inappropriately touched her several times and repeatedly asked her to have sex with him. The grand jury found Devault lied to his superiors in the Monongahela Police Department — where he was removed from his position — about his interactions with the woman and encouraged a co-worker to also lie. Defense attorney Blaine Jones said this is the first allegation of inappropriate behavior against his client with a long history of service.
