Below is information that I was able to find without doing much digging
Attached are PDFs of school newspapers around the time of her death. One mentions the witness. The other, a later article, discusses possible links to other attacks and also an unknown man that attacked her in her room at an earlier time.
[the second attachment will not upload for some reason. Click here if you would like to download it europa.iwu.edu/argus/pdf/19770422v083i23.pdf
Also, it appears the college that was helping in 2008 is Morton College Institute (see last paragraph of article).
Snips from an article in 2001:
'Now police say they have a fresh lead: newly discovered fingerprints lifted from crime-scene evidence stored in a police locker in Normal, where Rofstad was killed. Normal Police Lt. Rick Bleichner said the department sent clothing and other evidence to FBI analysts in a last-ditch effort to solve the case.
The FBI found fingerprints on one item that Bleichner described as a personal belonging of Rofstad's. It had never been analyzed for fingerprints before because police did not consider it a significant piece of evidence, Bleichner said.
Now police are running the prints through databases at the FBI and elsewhere to see if they can find a match and catch a killer in a case that has dogged two detectives and the victim's family. Police said results could be available in several months.'
'Police found an 18-inch piece of railroad tie, believed to be the murder weapon, near the crime scene. A witness driving by saw two men outside the sorority house with Rofstad, but thought they were "college kids goofing around," Sadler said.'
'There were strange things about the case: Rofstad had been attacked about a year earlier in her room at the sorority house by a man who crawled up the fire escape. That case was never solved, and some people still think the two incidents were related, Daniels said.
Rofstad had worked Dec. 22 at a clothing store, then stopped briefly at a bar before walking with a friend to her sorority house, Daniels said. The two women parted to go to their homes, after which Rofstad was attacked. Daniels said it is possible Rofstad was followed when she left the bar.'
Jennifer Lockmiller, 22, was found Aug. 28, 1993, strangled in her Main Street apartment. Normal police said the murder of the 22- year-old Illinois State University student remains open and under investigation.
Carol Rofstad, 21, an ISU student, was found beaten Dec. 23, 1975, outside a sorority house in the 600 block of South Fell Avenue and died the next day. Normal police never closed the case and last year received some assistant from Morton College's Institute for Cold Case Solution, but no arrests have been made.
NO connection between the two above cases that you know about.
Other then they both attented ISU, and lived in or around the Normal area?
Did thy check to see if any physical evidence from each case/scene may-had matched in some way to each other?

...END OF QUOTE.
The attack above occurred on July 15 1974.
Ill assume at the time, she was off from school for another school break?
The April 14 break ins, at least two were committed by the same person.
depending on the distance, within an hour of the two, same description as far as the face covered with pantyhose or something similar.
Was anything personal taken from either case that you know of?
Could have been a student at one of the schools?
The two attacks outside, may have been the same person.
Rape may have been the motive, and the killing may not had been a motive. Since she died on Christmas eve, i don't think he meant to kill her, just knock her out, like the other one before in 74 i believe coming home from the pajama party.
All of the break ins and the killing could have been committed by a student.
And she was seen, by a witness outside with the two men.
After this death, things seemed to have gotten quite, as far as other attacks break ins as far as i read.
If they still have those prints, that they retrieve from something personal from her, and still have not found a match. I would look back at the time, and any students whom may had been a p0I at the time, i would check to see if there still living, and ask for prints for comparison.
If they can do that , that is. This person may had stopped after the death. And has gone on to live a crime free life. Just speculation on my part.
ALL MOO AND SPECULATION, NOTHING FOR CERTAIN OR KNOWN AS FACT, UNLESS OTHERWISE KNOWN TO BE.
