 Vienna -An Austrian ice cream parlour owner has been found guilty of killing her ex-husband and a boyfriend before chopping them up with a chain saw and burying them in concrete in her shop's basement.

A Vienna court convicted the 34-year-old woman of murder on Thursday and handed her a life sentence, ordering her to be held in psychiatric care, according to Austrian news agency APA.

The woman, identified only as Estibaliz C, confessed to the murders on Monday but her lawyer said she will appeal.

The woman, dubbed the “Ice Lady” by Austrian media, shot the men in 2008 and 2010, putting their body parts in a freezer before burying them in her cellar. She had told the court her ex-husband failed to leave her alone and the boyfriend cheated on her. - Sapa-AP
