As of 10:30 a.m. on Sunday, the death toll had been raised to 50, according to Buddy Dyer, mayor of Orlando, with more than 50 injuries have been reported as well. While officials initially reported the Pulse shooting death toll as 20 people, the number was later corrected to 50 in a press conference by Orlando police and FBI officials. This makes the shooting the deadliest mass shooting in American history.

The former worst mass shooting in American history was the Virginia Tech shooting in 2007, which left 32 people dead and 17 injured. The Orlando death toll is now much greater than that, making the event that much more devastating.The Virginia Tech shooting also took place in two locations on the college's campus, while the Pulse night club shooting only occurred in one.

While no motive has been named for this event as of yet, the FBI and other domestic law enforcement are involved in the case, and are treating it as an incident of domestic terrorism.

Health officials in Orlando have asked for Orlando citizens to please donate O negative, O positive, and AB plasma blood in the wake of the tragedy.
