An uncle of the man who killed four Marines and a sailor in Tennessee has been in custody in Jordan since a day after the attacks on two military sites, a lawyer said Tuesday. Al-Khateeb identified his client as Asaad Ibrahim Asaad Haj Ali, a maternal uncle of the Chattanooga attacker, Muhammad Youssef Abdulazeez. A Jordanian official said Tuesday that he is sure the uncle and "other relevant people" in Jordan were being questioned, but he would not elaborate and or confirm that the uncle was detained.
