The 83-year-old murderers daughter told police that her mother had gone on a pilgrimage to the Vatican when they came to take her back to jail last November. Jarosz was arrested in Krakow, southern Poland, four weeks later.It has since been unclear whether Polish authorities will extradite the woman, but Polish authorities explained today (Fri) that the woman opted to serve the rest of her sentence in a prison in her homeland when offered this as an alternative to extradition to Austria.Officials did not say whether they will ask a doctor to check her condition again.
