FBI: 4th person involved in anti-Islam attack in Texas

In May 2015, Elton Simpson and Nadir Soofi, both from Phoenix, drove to Texas to open fire at an anti-Mohammed cartoon contest. Both Simpson and Soofi died in a shootout with police. Federal investigators are now revealing that days before the attack, Abdul Khabir Wahid (aka Abdul Khabir Hyman) met with Simpson and Soofi.
