VIENNA  - An Austrian court on Thursday convicted a woman dubbed the "ice killer" of murdering two men whom she cut up with a chain saw and concealed in the cellar of her ice cream parlour. Goidsargi Estibaliz Carranza Zabala, 34, who has joint Spanish-Mexican citizenship, was sentenced to life in a secure mental institution for killing her ex-husband in 2008 and two years later her new partner.

 "I can't say anything other than that I am sorry that I took Holger and Manfred's lives," a tearful Carranza said in a short final statement to the court in Vienna after a trial lasting four days. Chief prosecutor Petra Freh said the killings were "depraved and horrific," calling her a "highly dangerous woman ready to do anything." Carranza shot Holger Holz and Manfred Hinterberger, dismembered them and then concealed the parts in lumps of concrete that she then stashed in the cellar of her "Schleckeria" shop in the Austrian capital. The grisly remains were discovered by chance during maintenance work in June 2011. After going on the run to Italy, Carranza was captured several days afterwards and later extradited. The trial attracted considerable media attention and on Wednesday involved a PowerPoint presentation by a court-appointed medical expert of photos of the sawn-off heads and other body parts of the victims.
