ORLANDO, Fla. >> The murky picture of Orlando gunman Omar Mateen grew more complex Tuesday with word that the FBI is investigating whether he had been a regular at the gay dance club he attacked and had been living a secret life as a gay man.
As victims described the bloody horror of the massacre during a riveting hospital news conference, investigators continued to gather information on the 29-year-old American-born Muslim -- and took a close look at his wife, too -- for clues to the attack that left 49 victims dead.
