Illinois State University student Carol Rofstad, 21, was found beaten Dec. 23, 1975, outside a sorority house in the 600 block of South Fell Avenue. The suspected murder weapon, an 18-inch piece of railroad tie, was found nearby. Rofstad wasn't found until roughly 12 hours after the attack and died Christmas Eve as a result of head injuries. Two men, one of whom carried a club, were seen between 10 and 10:15 p.m. on Dec. 22, 1975. Both were white males and between the ages of 18 and 25. At the time of the attack, most students had already left campus for the holiday break, but Rofstad had stayed in the Twin Cities to work at a retail store. Money was found in her purse and there was no evidence of sexual assault. In 2001, Normal Police Department sent evidence to the FBI crime lab in Washington, D.C., hoping forensic analysis would provide fresh leads. A fingerprint was recovered but it did not match any in the FBI's computer database, and Normal police could not match it to fingerprints of one of its two primary suspects. Anyone with information in this case is asked to call the Normal Police Department at 309-454-9526, or Crime Stoppers of McLean County at 309-828-1111.
