'I Did the Shootings'
In a call to 911 dispatchers during his brutal attack on the Pulse nightclub in Orlando, Omar Mateen told authorities he was the shooter. "I'm in Orlando and I did the shootings," Mateen is recorded saying.
On Monday, the FBI released a partial transcript and a timeline of the events that occurred on June 12, when Mateen opened fire on club-goers killing 49 and injuring 53.
Mateen, who was shot and killed by police, killed 49 people and injured 53 others during his attack on the gay club.
