Forty-nine people were killed and 53 were wounded in the attack, which took place in the early hours of Sunday when Mateen, 29, of Fort Pierce entered, the gay nightclub on its popular Latin night and fired off more than 200 rounds of ammunition from a handgun and an assault rifle. He died in a shootout with Orlando police.
