Law enforcement officials on Monday afternoon identified the second man suspected of opening fire Sunday on a Muhammed cartoon contest near Dallas as Nadir Soofi, the Washington Post reported.
Soofi lived in Phoenix with Elton Simpson, the other suspected gunman in the attack, according to the Post.
FBI agents on Monday searched an apartment in Phoenix where Simpson and Soofi reportedly lived.
The two gunmen were killed after they opened fire on security officers outside of an event hosted by anti-Muslim group, the American Freedom Defense Initiative. The gunmen arrived near the event with assault rifles and began shooting at two officers, but one police officer shot and killed both suspects.
