An Austrian court on Thursday sentenced two brothers of Pakistani origin to life in prison for killing an elderly woman with an axe last year to get hold of her estate. The younger of the two, who is 31, admitted to the crime and told the court a dispute over Islam had led to the murder, but his 37-year-old brother denied killing the 74-year-old Austrian woman, who was his adoptive mother. The court in the southeastern city of Graz found the adopted son guilty of inciting his brother to kill the woman to rapidly get hold of a promised inheritance. The prosecutor had told the court money was the real motive behind her death, an opinion followed by the jury. The brothers said they would appeal the ruling.
