Surveillance footage from inside the Orlando club the night of the rampage shows Omar Mateen firing at people, stopping and then shooting again those who were already wounded, said officials who have viewed the evidence.
The video suggests “he was making sure anybody who was shot was dead,” said one official, who like others spoke on the condition of anonymity because the investigation into the shooting continues.
The footage corroborates eyewitness accounts that Mateen quickly emptied a 30-round magazine and then reloaded, proceeding to fire another 30 rounds into the wounded sprawled in front of him.
The video of the attack has become a key piece of evidence as officials piece together what happened in the early morning hours of June 19. The FBI declined to comment.
Eyewitness accounts so far indicate that Mateen killed most of his victims during the initial minutes of the massacre. He was using a Sig Sauer MCX rifle firing .223-caliber ammunition at a muzzle velocity of about 3,200 feet per second. And he was a trained shooter from his time as a student at a police academy.
