Here's a creepy one and there's actually a book about it called The Michigan Murders. A man named John Norman Collins- who is rumored to have been a Theta Chi (they're not on our campus anymore..hmmmm) killed 7 women in the Ann Arbor- Ypsilanti area between 1967 and 1969. I'm not sure if any of them were sorority women though, but at least one was an EMU student. He was arrested in 1969 at the age of 21. I read the book and it's really scary to know exactly where the places are that bodies were found and stuff. I think he actually lived in a house down the street from our house! Scary!
