Former investigator August Schenner, nearing 70, had been retired for five years from the Criminal Investigation Department in
In 1974, he said, he had investigated two murders. One woman had been strangled and left in the woods. The victim was Margaret Schaefer, 18, who was a friend of Barbara Scholz, a prostitute who had told the police what happened. She and Jack Unterweger had robbed Schaefer's house and then lured her into a car and took her into the woods. With a belt from her coat, Jack tied her hands behind her back, beat her, removed her clothes and demanded certain sexual acts. She refused, so he hit her in the head with a steel pipe. Then he used her bra to strangle her to death, leaving her nude body face up in the forest, covered with leaves.
When the police questioned Unterweger, he broke down and confessed. In court, he defended himself by claiming that as he had hit Fraulein Schaefer, he had envisioned his mother in front of him. His anger was such that he could not stop.
The forensic psychologist who examined him, Dr. Klaus Jarosch, pronounced him a sexually sadistic psychopath with narcissistic and histrionic tendencies. "He tends to sudden fits of rage and anger," Jarosch wrote. "His physical activities are enormously aggressive with sexually sadistic perversion... He is an incorrigible perpetrator."
The second murdered woman, Schenner said, was Marcia Horveth, a prostitute, who was strangled with her stockings and a necktie. Adhesive tape was applied to her mouth and her body was thrown into
While there, Schenner observed Unterweger in that environment, and hed had the impression that the young convict was running the place. He had some charm and people responded to him, including the guards. That was reason enough to suspect that, despite his sentence, he might have somehow talked his way into a parole hearing. Schenner had checked on this and discovered that fifteen years into his sentence, just a few months before Brunhilde Masser was murdered, Herr Unterweger had been paroled.
