More than 12 hours of body-camera footage from the vantage point of law enforcement officers is shedding new light on the chaotic moments that unfolded during the Pulse nightclub shooting.

On Thursday morning, the city of Orlando publicly released about 780 minutes — or 13 hours — of video on its public records page. The footage offers a more complete picture into what happened during the three-hour standoff between dozens of law enforcement personnel and gunman Omar Mateen.

The release comes almost one year to the date of the June 12, 2016 attack.

In the months following the mass shooting, hundreds of pages of 911 transcripts, incident reports and emails were released by the city. The 911 audio and pictures from outside and inside the club provided the public with an idea of what happened the night of the deadly attack.

The footage released Thursday is from body cameras worn by law enforcement officers from the Orlando, Belle Isle and Edgewood police departments.

The videos depict the efforts to take down the gunman and also how officers methodically and carefully rescued survivors from both inside and outside the club.

  • Officer: "Is anybody else in there?"
  • Victim: "I called 911... "
  • Officer: "Show us your hands."
  • Victim: "Please help."
  • Officer: "Come out, come out. We're police, man."

Last year, News 13 sorted through more than 400 calls that came into 911 dispatchers with various law enforcement agencies. The calls totaled about 22 hours of audio.

Cassandra Lafser, a spokeswoman with the city of Orlando, said certain media outlets agreed to pay for the body camera footage. The city then began redacting the footage for a public release, which happened Thursday morning.

Mateen killed 49 people and wounded 53 others in the worst mass shooting in modern American history.
