Unterweger claimed in interviews and his autobiography that his mother was occasionally engaged in sex work, but Austrian judicial records do not list any convictions or arrests for prostitution.

for a year. In February 1952, Unterweger was put into custody of his grandfather, Ferdinand Wieser, and his life partner Maria Springer, with whom he was to remain until the age of eight. Unterweger described Wieser as a philandering alcoholic and reputed "rough fellow" who regularly used his grandson to help him steal farm animals. Unterweger also alleged that his grandfather often brought home female strangers and forced Unterweger to watch the pair have sex. Government records, neighbours, and relatives, including Springer's two adult children who lived with the couple in the beginning, contradicted this characterization, saying that Unterweger was cared for and that neither Wieser or Springer drank excessively. Similarly, it was pointed out that Wieser did not go out regularly due to poor health, suffering from a partial facial paralysis, near-blindness and deafness of the left ear, as well as

's quarter for rehabilitation. After his release in December 1967, Unterweger continued to work as a waiter at various hotels, often being dismissed for workplace theft. Unterweger claimed that he joined a boxing club in St. Veit, where he supposedly had a 6-0 match record before being ousted after being falsely accused of stealing funds. Carinthia boxing federation president Karl Blaha and St. Veit Box Club chairman Willibald Piketz denied Unterweger's claims, saying he was never a member and that there was no record of either his fights or a theft linked to him. When Unterweger turned 18, the regional court sent a letter to his mother, informing her that they would not provide further social services to Unterweger as "educational measures are unlikely to be successful". From this point on, Unterweger drifted through Austria and worked occasional labour jobs.


First offences

Between 1966 and 1974, Unterweger was convicted sixteen times. His offences were mostly for theft and burglary, but throughout the early 1970s, the crimes also included

, as well as several counts of physical assault. Between 1968 and 1969, Unterweger served two sentences for theft, totalling ten months. In summer 1969, he was sentenced to four months imprisonment for burglary at a kiosk. In 1970, Unterweger was sentenced to seven months imprisonment for the kidnapping a minor from her legal guardians and theft, with the sentence extended by three months after he sent a threatening letter to a woman from prison. On 13 May 1971, in Salzburg, Unterweger lured sex worker Monika H. into his car, then drove her to the moors outside of the city. Inside the vehicle, Unterweger hit H. in the back of the head with a metal rod, stripped her naked, tied her up with underwear and sodomized her with the rod while masturbating. H. alerted passersby of the rape after which Unterweger was arrested. While jailed, Unterweger attempted suicide by overdosing on sleeping pills, for which he was transferred to a psychiatric unit and released without returning to police custody. Later sources claim that the rape occurred in 1974 and that the victim was a teenage student named Daphne. In August 1971, Unterweger crossed into

, where he lived at the time. There was no physical evidence against him, however, and his underage girlfriend at the time gave a false alibi, due to which the investigation was dropped. August Schenner, the lead officer in the homicide case, noted that Horvath's murder bore striking similarities to Unterweger's modus operandi. Schenner would unsuccessfully attempt to reopen the case to convict Unterweger of another murder in 1983 and kept in touch with Vienna's police department during their investigation into Unterweger during his serial murders in 1992. On 22 October 1973, Unterweger picked nurse Maria W. as a hitchhiker in

. Unterweger drove to Oberndorf, claiming he had to run an errand there and when the two were headed back to the main road, Unterweger abruptly braked the vehicle and began punching Maria W. while attempting to rape her. W. broke free of his grasp and fled into the woods while screaming for help. After another physical struggle, Unterweger relented and agreed to drive her to her parents back in Kitzbühel, convincing her to not press charges on the way over. W. relayed the actual sequence of events while being treated at her hospital in St. Johann and alerted the authorities on 20 November 1973. During police interrogation, Unterweger admitted to beating W., but claimed that he had undressed her in preparation for consensual sex and that most of her and his own injuries were the result of a car crash. Shortly after again being convicted of theft in March 1974, Unterweger entered an abusive two-week relationship with Elisabeth L. in

. The same month, Unterweger met Anneliese E. and moved to Switzerland with her, working as a disc jockey and waiter. There, the couple met West German national Barbara Scholz, who also became Unterweger's girlfriend, but shortly after Scholz was deported back to Germany, Unterweger and Anneliese E. followed suit in November 1974. Scholz and E. were both underage and financed Unterweger's lifestyle through prostitution alongside other teenaged girls.


First murder conviction

On the evening of 11 December 1974, Unterweger and Scholz burglarized the home of Scholz's parents in Ewersbach, when 18-year-old Margret Schäfer, a friend of Scholz, caught them in the act. They convinced Schäfer to keep quiet and accompany them in the car. After Scholz stole the equivalent of 100 schilling from an acquaintance's apartment, the group reached a parking lot, where Unterweger overpowered Schäfer, tied her up and stole her wallet, promising to release her outside of town. Unterweger stopped at the forest near Herborn and leaving Scholz in the car, Unterweger marched Schäfer into treeline. Unterweger beat her several times with an iron bar, tied her up with her pantyhose, raped her with the weapon and manually strangled Schäfer to death. After covering the body with dirt and leaves, Unterweger tied Schäfer's bra around her neck post-mortem to frame the killing as solely sexually motivated. In early January 1975, Unterweger, Scholz and Annelise E. committed a robbery at a jewellery store in Ewersbach and fled back to Switzerland. Running short on money, Unterweger called the parents of Anneliese E. and demanded ransom in exchange for her return. A handover was arranged at a bank in

and were autobiographical, though with the focus on his non-violent offences. The murder of Margret Schäfer is left out entirely, being replaced by a fictitious event in which Unterweger's character beats and urinates on a wealthy man who had solicited him for sex. Unterweger lied to von Eisenstein about the details of his murder conviction, saying he had killed Schäfer while experiencing a drug-induced blackout in which he hallucinated her as his mother, leaving out the preceding robbery and rape. He repeated a defence he had made during his trial, claiming that his criminal ways were the result of a traumatic childhood. He also invented a fictional "Aunt Anna", who was a supposed prostitute and murdered by a client in 1967. In reality, then 16-year-old Unterweger had read a newspaper article about the murder of an unrelated Anna Unterweger, really a kitchen helper who had been raped and killed by a homeless ex-convict in Salzburg. For years, he falsely claimed that her murder subconsciously contributed to his own mistreatment and later murders of women, and that the headline for the news article was "Her last customer was her murderer" rather than the actual, "Violent vagabond incriminated", believing that anyone who attempted to verify the story would not investigate for further details.

Austria

Between October 1990 and May 1991, Unterweger killed at least seven women in Austria. The victims were sex workers, two of whom were unregistered, with several of them having been previously solicited by Unterweger. The women were driven outside of town, beaten, raped, and left in forested areas. All were manually strangled, which was the cause of death for most, while some were asphyxiated with underwear such as bras, pantyhoses or stockings. * 27 October 1990,
