Five days before a 16-year-old Yukon girl was stabbed to death, she and her dad complained to Oklahoma City police that she had been repeatedly raped and threatened with guns and knives by the girl's 32-year-old ex-boyfriend and former alternative school drill instructor, who later killed her. Oklahoma City police never contacted the teacher before the killing, a department spokesman said Wednesday. They also didn't interview two other teenagers the Yukon girl reported also were having sex with the man they all met as students at a Canadian County alternative school, the department spokesman said. It took two days before the case was assigned to a police officer, Oklahoma City police Capt. Steve McCool said. "The police department cannot protect everyone against violence. We just can't,” McCool said. "We give people advice on the ways they can help themselves, but we can't put a 24-hour bodyguard with them.” Former drill instructor Robert Paul Roberson went to the apartment of stabbing victim Bailey Rian Thrasher about midnight Friday, abducted her at gunpoint and led a Yukon police officer and Canadian County deputy on a brief chase. Officers were able to run Roberson's car off the road, but were forced to shoot him to death when they walked to the car window and saw him stabbing Bailey. The Oklahoma State Bureau of Investigation is investigating whether officers were justified in firing their weapons, said Jessica Brown, Oklahoma State Bureau of Investigation spokeswoman. Information also is being compiled that will be used to help educate law officers about how to avoid similar tragedies in the future, Brown said. "There are so many reasons this shouldn't have happened,” Brown said, referring to a series of events that unfolded during the past two years.
Report filed days earlierOn Aug. 27, Bailey went to Oklahoma City police and accused Roberson of having sexual relations with her and two other students from a Canadian County alternative school, where Roberson was a drill sergeant until he resigned in May. Bailey had been attending school in the spring of 2006 because of drug problems. The police report was filled out by hand by Bailey and her dad, Darin Thrasher, on Aug. 27. The report was entered into police computers Aug. 28 and assigned to a detective on Aug. 29, McCool said. The investigation was in its preliminary stages when Bailey was killed, he said. McCool said just because a report is filed, that doesn't mean an arrest can be made. Police can't make an arrest "on a hunch and we can't arrest just because someone says so,” he said. While an investigation is in its early stages, officers give victims information about how they can obtain protective orders and keep themselves safe, he said. Roberson repeatedly threatened Bailey with knives and guns, physically abused her, sent threatening text messages and forced her to have sex with him three times a week after she tried to withdraw from their relationship, the report states. The Thrashers reported they came to police because they were "tired of running and hiding.” The report also states: •Bailey told police she began having sex with Roberson in February 2005, when she was 14, and that Roberson had "left his wife and children for Bailey.” •Bailey began living with Roberson when she was 15. They initially lived in an apartment, but later moved to a house at 12017 NW 7 in Oklahoma City. •Her father told police he initially was unaware of their dating relationship and first learned about the inappropriate relationship in August 2006. He also said that at first he thought "Robert was a good influence on Bailey because he hated drugs and Bailey had gotten involved in drugs.” •In March, Bailey began to pull away from the relationship, at which time Roberson "ramped up” the threats against her. He would demand that she come to his house and have sex with him three times a week, or he would continue the threats. •Bailey also said two other girls at the alternative school had sexual relations with Roberson, one of whom was 15 years old.
