Orlando Nightclub Attack: What We Know

More details are emerging about the man who carried out Sunday’s shooting rampage that killed 49 people.

Here’s what we know:

—President Obama said it appears “the shooter was inspired by various extremist information that was disseminated on the Internet,” and FBI Director James Comey added that investigators are “working to understand what role anti-gay bigotry played in motivating this attack.”

—The death toll in the Pulse nightclub stands at 49, plus the attacker. The Orlando Police Department had previously said there were 50 victims.

—The Islamic State claimed responsibility for the attack, though it is unclear whether the organization directly planned the attack or if Mateen carried it out independently. 

—Mateen, a New York-born U.S. citizen, was a resident of Port St. Lucie, Florida. On Sunday, the FBI said it had questioned him in two separate terrorism-related investigations in 2013 and 2014, both of which ended inconclusively.
