ISIS Claims Responsibility, Authorities Tracked Gunman
They suspected he was dangerous. Elton Simpson, one of the gunmen who opened fire Sunday at an anti-Islam event in Texas — an attack ISIS claims responsibility for — was on the FBI’s radar since 2006. He was arrested in 2010 for trying to join jihadists in Somalia, but was only convicted of lying to agents. Authorities shot and killed Simpson and his fellow attacker, Nadir Soofi, and they’re now scouring the gunmen’s electronic communications to determine whether they were really in touch with foreign militants.
