ROUGH CUT (NO REPORTER NARRATION) STORY: Florida Representative Alan Grayson told reporters on Sunday (June 12) that the gunman in the massacre at an Orlando, Florida nightclub was identified as Omar S. Mateen. A gunman killed 50 people and injured 53 in a massacre at a gay nightclub in the tourist hub early on Sunday, the city's mayor and police said, in an attack U.S. authorities are describing as a "terrorism incident." Mateen was identified as a man that a senior FBI official said might have had leanings towards Islamic State militants. Officials cautioned that the Islamist tie required further investigation. The death toll given by Orlando Mayor Buddy Dyer to reporters made the attack the deadliest mass shooting in U.S. history, eclipsing the 2007 massacre at Virginia Tech university, which left 32 dead. A police officer working as a security guard inside the Pulse nightclub, which has operated in downtown Orlando since 2004, exchanged fire with the suspect at about 2 a.m. (0600 GMT), police officials said. A hostage situation quickly developed, and three hours later a squad of officers stormed the club and shot dead the gunman. It was unclear when the gunman shot the victims.
