On Dec. 9, 1977, Nancy Jo Fox was found dead in the bedroom of her apartment at 843 S. Pershing.
A nylon stocking was wrapped tightly around her neck, and District Coroner Dr. Robert Daniels confirmed that she died of strangulation.
One lead police had was an anonymous man who called them at 8:20 that morning and told them where the body was.
Fox, 25, was found partially clothed, lying face down on the bed with her hands and feet bound with nylon stockings.
An employee of Helzberg's Jewelers, Fox left work at 9 p.m. Dec. 8 and was not seen alive again. Detective Capt. Al Thimmesch said she apparently was slain shortly after she arrived at her apartment.
A window at the back of her duplex had been smashed, and there was evidence that the apartment had been burglarized, police said.
The phone had been taken off the hook and the lines had been cut on the outside of the house.
Detectives said the contents of her purse had been dumped on a coffee table, and her sweater had been draped neatly over a chair.
The slaying was reported at 8:20 a.m. Dec. 9, and police traced the call to a phone booth at Central and St. Francis.
A witness later told police that he had seen the caller.
According to Thimmesch, the witness said the caller was a white male, about 6 feet tall and had blondish hair.
Thimmesch said the witness told police the caller was wearing a "blue-gray industrial-type uniform or outfit and possibly a hat which had earflaps."
Thimmesch said the caller apparently was driving a "late-model van, probably not over two or three years old, which may have had some type of writing, possibly advertising, on the side of it." He said the van did not have windows.
"We're reasonably certain that the man who called to report the homicide was the same man who killed Fox," Thimmesch said. "He knew too many things about her."
The detective would not elaborate.
Fox was described by a neighbor as "a loner" who seldom entertained friends.
She apparently had lived in the southeast Wichita duplex for about two years. The other apartment in the duplex was vacant.
