Austria's Supreme Court on Tuesday upheld a life sentence on a woman who stuffed her newborn babies into a freezer or entombed them in cement-filled buckets, AP reported. A court in the southern city of Graz, where four tiny bodies were discovered in the summer of 2005, convicted Gertraud Arzberger, 33, in March of three counts of murder and sentenced her to life in prison. She had pleaded guilty to killing the four babies, but experts said they could not rule out that one of the four might have been stillborn.
