Witnesses and others said the shooting left behind a gruesome scene. A doctor at a nearby hospital said victims came in with their bodies riddled with gunshots.

Ricardo J. Negron commented on the club’s Facebook page several hours after the attack: “I was there. Shooter opened fire @ around 2:00am. People on the dance floor and bar got down on the floor and some of us who were near the bar and back exit managed to go out through the outdoor area and just ran. I am safely home and hoping everyone gets home safely as well :(”

The shooter has been identified.

The suspected gunman was identified by relatives and law enforcement officials as Omar Mateen, a 29-year-old from Fort Pierce, Fla. He was armed with a 9mm semiautomatic Glock 17 pistol and a .223-caliber Sig Sauer MCX AR-15-style assault rifle, both of which were purchased legally in the previous few days, according to ATF. Investigators also said they found a third gun in Mateen’s car.

According to the FBI, Mateen spoke with 911 operators and Orlando police negotiators multiple times during the three hours he held hostages in the club. During those conversations, he called himself an Islamist soldier, pledged loyalty to the Islamic State, and claimed to have explosive vests and bombs with him and in his car. (Police found no explosives afterward.) Ron Hopper of the FBI said Mateen had been investigated and interviewed twice by the bureau before the probes were concluded.
