PHOENIX (AP) -- An attorney says Travis Alexander's siblings will file a wrongful death lawsuit against Jodi Arias. Arias was convicted of first-degree murder Wednesday in the gruesome killing of her one-time boyfriend in his suburban Phoenix home. Her four-month trial included graphic details of their sexual escapades and photos of Alexander just after his death. Attorney Jay Beckstead thanked the Maricopa County attorney, the detective, and said the siblings "appreciate the outpouring of support they have received from the public." Authorities said Arias planned the attack in a jealous rage after being rejected by the victim. She said it was in self-defense.
