CHICAGO (WLS) -- In Madison, Wisconsin, the I-Team has learned that two men are charged in a rash of separate sex attacks on or near the University of Wisconsin campus. These are the latest cases in a disturbing trend of college assaults.
The campus sex attacks in Madison occurred as students were returning for fall classes. These two men were arrested and charged in separate cases. One occurred in an alley near a bar, the other in a parking lot. And a third, unrelated attack in the past three weeks there apparently remains unsolved.
Police say these were stranger attacks, which is unusual on campuses, where most involve known suspects - and many go unreported.
"You're a victim, you call the police," said Josh Weitzman, Chicago's Finest Tactis.
The I-Team began investigating the under-reporting of sexual assaults on campus earlier this year.
This summer, Missouri Senator -- and former sex crimes prosecutor -- Claire McCaskill looked into how schools deal with campus rape reports. Her national survey of 440 colleges and universities showed that more than 40% of those schools have conducted no investigations of alleged sexual assaults in the past 5 years. The survey also found that a third of the schools failed to properly train officials who deal with sexual assault claims.
"It's called the Red Zone. It's from the time freshman get to school, their first day, up until about Thanksgiving break, that is where they are most vulnerable to become victims," said Jack Shilney, Chicago's Finest Tactics.
Tuesday night at 10 p.m., the I-Team ventures into "the red zone" to see what campus administrators and police are doing to protect students.
