Harrowing new footage of Pulse nightclub shooter Omar Mateen has been released, revealing the moment Omar walked past the front security guards and opened fire seconds later in the bar.
The graphic video timeline was played in court on Thursday by federal prosecutors in a case against Mateen's widow Noor Salman, who turned her head away from the monitors and began to cry.
Salman, 31, is accused of helping her husband carry out the mass shooting that killed 49 people and wounded 58 at the gay nightclub, and of lying to law enforcement afterwards.
The video, presented to a jury of 12, revealed surveillance footage of Mateen passing security guards, paying admission, and entering the club at 1:41am.
Just before 2am he leaves to move his rental van closer to the club. When he re-enters, he's armed with an automatic weapon, a Glock and a knife, immediately opening fire seconds later.
The surveillance video also sees Mateen reload his gun several times. At one point his semi-automatic jammed, but he had a hand gun holstered to his side.
