Upon seeing the girl who fell into the library, witnesses did not even realize that she had been killed.

On November 28, 1969, Betsy Aardsma went to the Pennsylvania State University Pattee Library. She was an English BA working on a project, writes historicmysteries.com. Initially, Mr. Aardsma spoke with a teacher in his office inside the library building. Then between 4:45 pm and 4:00 pm In 55 minutes he went to row 51. This area was in the basement of the library, lined with narrow bookshelves. A witness, who was in the same area, later said that he heard two people in line talking: a man and a woman. He said the votes were not raised and it did not appear to him that there was any conflict between them. A witness said he soon heard the sound of books falling and someone crashing into one of the bookshelves.

What about Betsy Aardsma?

Sometime before 5 pm a man came out of the library and the staff said, “Someone better help this girl.” The watchman did not realize what this meant, so he remained at his post. Soon, other students discovered Betsy lying on the ground. At first it looked like he was passing out or had some kind of seizure. Several students tried to revive her. One of them even started mouth-to-mouth artificial respiration. However, no one suspected that Betsy might have been a victim of violence. Some witnesses later testified that two men left the library instead of one.

Betsy was taken to a hospital in the university complex, Ritenour Health Center. A doctor saw a stab wound through his left chest. A sharp object damaged the heart’s right ventricle, but there was very little blood in Betsy’s body. Not only that, Betsy was wearing a red dress that hid the bloodstains. This was probably why the students who found her did not realize that Betsy had been murdered. There were no signs of defense on her hands, and this led police to believe that Betsy had been attacked from behind.

By the time the police went to the crime scene, the janitor had already thoroughly cleaned the library floor and arranged the shelves. Unfortunately, this destroyed any potential leads.

The police were questioned by thousands of men after the crime. Aardsma’s search for the killer covered the entire university complex and its surroundings. The assistant helped an artist create a picture of the man he was briefly chatting with. However, this did not help identify any suspects.

Renewed interest in the murder of B. Aardsma

This case remained silent until the Internet age, when a superficial hobbyist created a website called “Who Killed Betsy Aadsma? Opening the most famous pending case at the University of Pennsylvania ”(Who Killed Betsy Aardsma? Uncovering Penn State University’s Most Notorious Unsolved Crime). This site (no longer exists, aut. Past). It has generated official reports, current and past articles on the subject, a crime scene photo gallery, and images of potential suspects.

In addition, with the advent of the 21st century, two books have been published on the murder of Betsy Aardma and her investigation. In both books, the main person is considered the main suspect. Both Derek Sherwood’s “Who Killed Betsy ?: Uncovering Penn State University’s Most Notorious Unsolved Crime” and David Deco’s “Murder in the Stacks: Penn State, Betsy Aardsma, and the Escaped Killer” (” Killing Between the Shelves: Pennsylvania, Betsy Aardsma and the Killer Who Got Away “.

Mr. Haefner was one of the men interviewed by the police and fired immediately after the crime. In later years, Haefner’s only known criminal activity was the abuse of underage children. However, it was very different in nature than the murder of an adult woman, and various theorists are still convinced that Haefner is not involved in it. In any case, Haefner is already dead: he left the world in 2002. The police did not identify any more possible suspects. True, some amateur investigations had yet to name Ted Bundy as a possible culprit.

The Betsy Aardsma case remains unsolved and, after more than 50 years, is frozen. But officially, the investigation is still ongoing and officials are still waiting for the unlikely miracle that they will one day uncover the infamous University of Pennsylvania murder.
