An 18-year-old University of Minnesota student was raped in her superblock dorm room early Sunday morning, University police said. The alleged attacker lives in the same residence hall, which police would not identify, and was an acquaintance of the woman, Deputy police Chief Chuck Miner said. Police collected information on the suspect from the woman, who came to the University police station to report the incident later that night, according to a University police report. Police have identified a suspect and are currently investigating the crime, Miner said. In 2008 there were 11 residential reports of forcible sex offenses, according to UMPD statistics. The figure includes rape as well as forcible fondling. The National Center for Posttraumatic Stress Disorder recently reported that only 18 percent of sexual assaults are committed by strangers. âÄúWhereas most of us have been raised to fear a stranger sexual assault âĦ in fact itâÄôs the non-stranger sexual assault thatâÄôs the most common kind,âÄù Donna Dunn, executive director of the Minnesota Coalition Against Sexual Assault said. Dunn said people can become dangerously complacent in comfortable, familiar settings. âÄúWe donâÄôt necessarily want to evaluate the people we know as whether theyâÄôre dangerous. ThatâÄôs something we tend to resist,âÄù Dunn said. âÄúSometimes the comfort of a dorm can allow people to put their guard down.âÄù Dunn said intervention is another key to preventing sexual assault. âÄúPeople need to be addressing what looks like the beginning of perpetrating behavior,âÄù Dunn said. âÄúEspecially on college campuses, I think we really need to empower bystanders to intervene when they see somebody who routinely âĦ push[es] boundaries.âÄù
