FBI Questioned Gunman in Bank Standoff in April The gunman killed during a hostage standoff at a Louisiana bank this month allegedly told the FBI in Yemen months earlier that he was hearing voices and had contemplated suicide, but wasn't a danger to others. A statement issued by the FBI on Friday said agents interviewed 20-year-old Fuaed Abdo Ahmed in April after his family reported him missing. The FBI also said the Department of Homeland Security interviewed Ahmed at Los Angeles International Airport upon his return to the U.S. in June after learning that a Facebook photo showed him holding an assault rifle during his visit to Yemen. Ahmed was taken to a medical facility for a mental evaluation. Louisiana officials said Ahmed wasn't under surveillance before the bank standoff because he hadn't committed any crimes.
