6/13/2016: Orlando Nightclub Gunman Scouted Walt Disney World as Potential Target

The gunman behind the Orlando nightclub shootings, the deadliest mass shooting in American history, recently scouted Walt Disney World as a potential target, a federal law enforcement source tells PEOPLE.

Omar Mateen and his wife, Noor Zahi Salman, visited Walt Disney World in April, the source says. Salman told federal authorities on Sunday that her husband had more recently been “scouting Downtown Disney and Pulse [nightclub] for attacks.”
