(AP) — A man convicted of killing the father and sister of his former girlfriend in a fiery attack on the family's Southern California home was sentenced to death Tuesday. Iftekhar Murtaza, 30, was sentenced for the murders of Jay Dhanak, 56, and his daughter Karishma, 20, in May 2007, the Orange County district attorney's office said. Authorities said Murtaza and a friend torched the family's Anaheim Hills home and kidnapped and killed Dhanak's father and sister, leaving their stabbed bodies burning in a park 2 miles from Dhanak's dorm room at the University of California, Irvine.
