A survivor of the Orlando attack who was shot 3 times has described playing dead while Omar Mateen fired relentlessly at people on the floor.
Angel Colon told reporters Mateen had continued to shoot at club-goers who already appeared dead.
6 people remain in critical condition following the attack at the Pulse homosexual night club.
Trauma surgeon Michael Cheatham said he "would not be surprised" if the death toll, currently at 49, rose.
Authorities say, that Mateen, who was killed by police, pledged allegiance to so-called Islamic State shortly before the attack.
The attack, in which 53 were wounded, is the worst mass shooting in recent US history.
