A series of photos shows the devastating scene left after Omar Mateen opened fire inside an Orlando gay night club killing 49 people and injuring dozens more. Mateen, who became the worst mass shooter in American history, shot more than 100 people with an AR-15 assault rifle and handgun on the dance floor at Pulse night club early Sunday morning.
Investigators are examining evidence at Pulse nightclub in an attempt to uncover exactly what happened at the nightclub.
Sunday night, workers were removing bodies four at a time on stretchers out of the club and loaded them into white vans. The action was repeated over and over. The covered bodies were taken to the County Medical Examiner's office.
On Monday, officials said they had identified 48 of the 49 victims, and are working to inform their families. Once their families have been informed, the names will be released online. So far, 26 of those names have been released. Thirty-nine of the dead were killed at the club, and 11 people died at hospitals, Orlando Mayor Buddy Dyer said.
Mateen, who purchased the weapons legally, had been investigated by the FBI three times but the bureau did not take further action. Concerns about homophobic remarks he made whilst at work did not stop him from being employed as a security guard at G4S for nine years. The company offers security advice and personnel to countries around the world and also secures some US nuclear sites.
The gunman exchanged fire with an officer working around the club at 2am before going back inside, according to Orlando Police Chief John Minia.
Mateen went on to exchange gunfire with 14 police officers at the club, and took hostages at one point. In addition to the assault rifle, the shooter also had a handgun and some sort of 'suspicious device,' Police Chief John Mina.
