Approximately 20 People Were Shot To Death At A Gay Nightclub In Orlando

Update 10:55 am EST:

According to NBC News, at least 50 people died and more than 50 have been injured in what is now the deadliest mass shooting in US history.

On Satuday morning, Orlando Police Chief John Mina briefed the press on the details of Christina Grimmie's tragic shooting. Just a day later, he did the same for many more.

Early Sunday morning, a mass shooting took place at Pulse, a gay nightclub in Orlando. The gunman, who came armed with an assault rifle and handgun, took about 20 lives, Mina said in a press conference on Sunday morning.

The chief also said 42 people had been transported to various local hospitals.

There were around 320 people at the Pulse nightclub, police say, and the entire incident seemingly spanned around three hours, with Chief Mina telling media an officer first reported a gunman at Pulse at around 2 am on Sunday morning. At around 5 am, SWAT personnel had exchanged gunfire with the suspect, who was killed on site.

Images from outside the nightclub show patrons and family members visibly shaken up. One person who was inside of Pulse at the time said that she mistook the gunfire for music.

Rosie Feba told the Los Angeles Times,

She told me someone was shooting. Everyone was getting on the floor. I told her I didn't think it was real, I thought it was just part of the music, until I saw fire coming out of his gun.

The FBI will be assisting Orlando police with the investigation into what is now the city's second high profile shooting in as many days.
