Kuwait's Supreme Court on Tuesday upheld a death sentence against a Philippine housemaid for killing her employer's seven-year-old son by slitting his throat, a legal source said. May Membrini, as the name was given in court documents, was convicted of killing the boy in January last year, as well as attempting to kill his older brother and sister who sustained injuries. Afterwards she allegedly jumped from the second story of her employer's home. A police source said at the time that Membrini - who had been in Kuwait for six months - had quarreled with her employers. The court ruling is final and only needs to be signed by Kuwait's Emir Sheikh Sabah Al-Ahmad Al-Sabah to be implemented. In December, the Kuwaiti ruler agreed to commute the death sentence to life in jail for another Filipino maid, Marilou Ranario, who was convicted of killing her employer, after a visit by President Gloria Arroyo. Membrini was sentenced to death by a lower court in July last year and the appeals court confirmed the ruling in September. Death sentences in the Gulf state are carried out by hanging. __
