A Clark County judge on Monday sentenced a man accused of raping two women in Clark County to 18 years in prison.Tracy Loren Montgomery, 32, of Vancouver pleaded guilty earlier this month to first-degree rape and second-degree assault. He also entered a Newton plea — acknowledging that a jury could find him guilty of a crime but not admitting guilt — for third-degree rape.Montgomery first appeared in court in April 2015, after he was arrested on suspicion of a February 2015 rape and another rape in September 2014.In February 2015, a woman contacted the Vancouver Police Department to report that she had been assaulted and possibly raped after going to the now-closed Q Nightclub & Lounge in downtown Vancouver with friends. According to court records, she met Montgomery at the bar and agreed to give him a ride home. She let him drive because he knew the way.Montgomery drove them to a remote area on Lower River Road. When she asked where they were going, he assaulted her, punching her in the face. He pulled over to the side of the road, where he grabbed her by the throat, kept punching her and began removing her clothes, according to court records.She lost consciousness at times, and Deputy Clark County Prosecutor Aaron Bartlett said Monday that the woman was unsure whether she was raped until DNA evidence matching Montgomery confirmed it.Court records said the woman identified Montgomery as her attacker, and that investigators contacted staff at the nightclub, who were able to identify him as the man at the club. Montgomery pleaded guilty to first-degree rape and second-degree assault in the case on Oct. 5.
