Estibaliz Carranza and the Vienna Double Murder

Two deaths, two years apart

Holger Holz, Carranza's former husband, was killed in April 2008. Manfred Hinterberger, her later partner, was killed in November 2010. The two deaths remained hidden until repair and construction work in the cellar of the Vienna property exposed human remains in June 2011.

Reporting from the subsequent prosecution established that Carranza had concealed the victims' remains in the cellar associated with the ice-cream shop she operated. The discovery connected what had previously appeared to outsiders to be unexplained absences.

Flight, arrest and extradition

After the discovery, Carranza left Austria and was arrested in Italy under a European arrest warrant. Italian authorities approved her extradition to Austria. By that stage, reporting said she had admitted responsibility for both killings.

The extradition returned the case to Vienna, where prosecutors prepared a double-murder case. The evidence did not depend on rumor about the defendant's private life: the prosecution centered on her admissions, the recovered remains, the concealment and the circumstances of the two deaths.

The 2012 trial

The Vienna trial began in November 2012. Carranza admitted killing both men. A jury found her guilty of both murders, and the court imposed life imprisonment together with placement in a secure institution for offenders requiring psychiatric treatment.

Psychiatric evidence presented at trial described serious personality disorders but did not find that she lacked criminal responsibility. That distinction matters: the secure placement was part of the sentence, not an acquittal by reason of incapacity.

The victims and motive evidence

Carranza gave accounts of conflict within both relationships, and the defense asked the court to consider those circumstances. The jury nevertheless convicted her of murder. The appellate court later emphasized the calculated and treacherous character of the killings when it upheld the maximum sentence.

This file does not convert either the prosecution's characterization or Carranza's own relationship narratives into a single psychological explanation. The proved facts are the two intentional killings, concealment, confession and convictions.

Appeal and final judgment

At the end of the 2012 trial, Carranza's lawyers announced appellate challenges. On 20 March 2013, the Vienna Higher Regional Court rejected the challenge to the life sentence. Austrian reporting described the double-murder judgment as legally final after that decision.

The appellate panel left both the murder findings and the secure psychiatric placement intact. This is why the archive classifies the case as Solved / Adjudicated, rather than relying only on the first-instance verdict.

Timeline

Current status

The case is Solved / Adjudicated. Estibaliz Carranza was finally convicted of murdering Holger Holz and Manfred Hinterberger and remains subject to a life sentence. The two killings are kept together in one dossier because they formed the same prosecuted double-murder case and should not be artificially split to increase the archive count.
